Cortisol and Strength Training!

Before your feet touch the floor in the morning your brain is already likely to be running through responsibilities and unfinished tasks. For many people that mental checklist can trigger a stress response almost instantly. Our heart rate rises, muscles tense and stress hormones begin circulating through the body. While short bursts of stress aren’t necessarily harmful, when the body spends time operating in a heightened state of alertness our cortisol levels can spike and begin to work against us rather than for us. Along with regular strength training and purposeful movement, this can help restore balance and improve the body’s ability to manage stress.

Understanding Cortisol

Cortisol is a hormone made by the adrenal glands and it acts as the body’s built-in system for managing stress. Many of us don’t know that its role goes far beyond stress – it influences almost every major system in the body, from energy levels and metabolism to immune function and sleep. Cortisol follows a fairly predictable daily rhythm. Levels are highest in the morning, helping you wake up, feel alert and prepare for the demands of the day. Throughout the afternoon and evening, cortisol gradually declines, allowing the body to relax and prepare for sleep.

What Cortisol Does

Provides energy when you need it
Cortisol helps release stored energy by mobilising glucose, fats and amino acids, ensuring your body has fuel available during physical activity or stressful situations.

Supports metabolic function
It works alongside insulin and other hormones to regulate blood sugar and energy balance.

Helps control inflammation
Cortisol acts as a natural anti-inflammatory, helping prevent the immune system from overreacting.

Maintains cardiovascular function
Healthy cortisol levels support normal blood pressure and circulation.

Regulates mood, focus and sleep
Its daily rhythm contributes to mental clarity during the day and restorative sleep at night.

When Stress Never Switches Off

When faced with intense stress, cortisol and adrenaline rapidly increase, preparing the body to respond. Energy is redirected toward muscles and critical systems while less urgent functions (digestion and recovery) can temporarily switch off. Financial concerns, work pressure, social obligations and constant connectivity (late night scrolling!) can keep the body in a prolonged activation. Over time consistently high cortisol levels are associated with:

  • Persistent fatigue and poor sleep quality
  • Increased abdominal fat storage
  • Reduced muscle recovery
  • Elevated blood pressure
  • Impaired immune function
  • Difficulty concentrating, mood disturbances and anxiety
  • Increased risk of metabolic disease

Why Exercise Helps Regulate Cortisol

Think of training as controlled stress… During a workout, the body experiences a manageable challenge. Cortisol rises to support performance, energy production and adaptation. Once the session ends and recovery begins, hormone levels gradually return – repeated exposure teaches the body to become more resilient.

Research suggests that when we’re physically active we often have healthier cortisol patterns, lower resting stress levels and faster recovery following stressful events in comparison to not including any physical activity.

Strength Training and Cortisol

Strength training is key to supporting and controlling stress management. A thoughtful resistance training programme improves:

  • Muscle mass and strength
  • Metabolic health
  • Bone density
  • Confidence and mental resilience
  • Recovery capacity

When we’re lifting weights cortisol naturally rises to help meet the demands of this type of training. Problems typically occur when we focus on intensity or avoid recovery. To maximize benefits in your own fitness journey be sure to focus on progressive overload (we focus on this in my classes, see an example below) rather than constant exhaustion. Prioritising quality sleep and nutrition, and including recovery days throughout the week is equally as important. Do you ever feel your body saying it needs rest? It’s important to listen to your body on these days especially during stressful periods.

The Best Types of Exercise for Stress Balance

1. Strength Training

Resistance training provides both physical and psychological benefits. 3-4 structured sessions per week can improve stress resilience while supporting long-term health and performance.

2. Moderate Cardiovascular Training

Walking, cycling, swimming, rowing and light jogging can significantly reduce stress levels while improving cardiovascular health. A quick 20-30 minute walk is often enough to improve mood and lower tension. Plus you will never regret getting outside for a walk!

3. Mind-Body Movement

Activities such as yoga, mobility work and pilates combine movement with controlled breathing, helping activate the body’s relaxation response. These sessions can be particularly valuable on recovery days and pair so well with strength training.

4. High-Intensity Training

HIIT workouts can be effective and time-efficient, but they need to be done correctly. Because they place a greater demand on the nervous system, most people benefit from limiting HIIT to one or two sessions per week and balancing them with lower-intensity recovery-focused activities.

A Simple Weekly Plan for Managing Stress and Building Strength

My weekly 4 x 30 min strength training platform targets each muscle group, allows for rest and recovery and is suitable for all ages and fitness levels. In the programme we focus on functional fitness, using compound movements – not just isolation. Practicing this type of training builds and mimics your daily movements to support you in every stage of life.

Monday: Full body strength – using heavier but manageable weights with progressive overload targeting the full body

Tuesday: Arms and abs – endurance with lighter weights and lots of reps, focussing on the upper body

Wednesday: Lower body – using bodyweight or resistance bands and weights. Mobility to start, firing up the calves, glutes and hamstrings

Thursday: Mobility work, yoga, or active recovery

Friday: HIIT full body workout – no repeats, a mixture of strength and cardio

Saturday: A long walk

Sunday: Rest, stretching, recovery

You can try a free class here.

A Final Thought

Healthy cortisol levels help you wake up energised, perform at your best, recover effectively, and maintain overall health. The challenge comes when chronic stress prevents the body from returning to balance. Regular movement (particularly strength training!) combined with adequate recovery is one of the most effective tools for improving stress resilience.

Strength Training for Better Posture in Midlife Women

As we move through each life stage, changes in posture can happen gradually and go unnoticed. You may find yourself slouching more, experiencing stiffness in your neck and shoulders or dealing with recurring back pain. While these changes are common, they aren’t inevitable. Particularly during and after menopause we naturally lose muscle mass and strength which can lead to weakened muscles that are responsible for supporting good posture. When the muscles, core, back, hips and shoulders become weaker, the body can struggle to maintain proper alignment. This can result in rounded shoulders, a forward head position and increased strain on the lower back. One of the most effective ways to improve posture and support overall health during midlife is through strength training.

What Can I Do To Improve My Posture?

Strength training targets the muscles that support the spine and keep the body upright. By building strength in key areas, you create a stronger foundation for better posture and more efficient movement.

The Core

Your core acts as a natural corset for the body. Strong abdominal and deep stabilising muscles help support the spine, reducing stress on the back and improving posture throughout the day.

Try: Dead Bugs. I include these in many of my classes! The dead bug is a simple but effective exercise that strengthens the deep core muscles responsible for spinal stability while teaching the body to maintain a neutral posture during movement. You can do them weighted or with just your body weight.

The Upper Back

Exercises that strengthen the upper back and shoulders (posterior deltoids especially) help counteract the effects of sitting and screen use. These muscles work to pull the shoulders back and encourage a more upright position.

Try: Resistance Band Rows. All you need is a band, you could also do this with dumbbells. Rows strengthen the muscles between the shoulder blades, helping to reverse rounded shoulders and support a taller, more open posture.

Hip and Glute Strength

Strong glutes and hips help maintain proper pelvic alignment, which plays a significant role in posture and lower back health.

Try: Glute Bridges. This exercise activates and strengthens the glutes, helping to support the pelvis and reduce excessive strain on the lower back – you can also add a band.

Balance and Stability

Strength training improves body awareness, coordination and balance, helping you move with greater confidence and reducing the risk of falls.

Try: Single-Leg Stands. Standing on one leg challenges balance and strengthens the stabilising muscles around the ankles, knees, hips and core, all of which contribute to better posture and stability. There are lots of single leg exercises which are excellent for improving balance – reverse lunges are another alternative here.

The Benefits Extend Beyond Posture

While standing taller is a noticeable benefit, strength training offers much more for midlife women.

Reduced Aches and Pains

Improved muscle strength can help relieve tension in the neck, shoulders, and lower back by reducing the strain placed on joints and connective tissues.

Increased Bone Health

Many of you may not know that resistance training helps stimulate bone growth and maintain bone density, making it an important tool in reducing the risk of osteoporosis. While my classes aren’t designed specifically for those with osteoporosis, we do have members on the platform who have been diagnosed and comment on how these circuits have improved their condition and overall joint health.

More Energy and Confidence

Poor posture can be surprisingly tiring. When your body is out of alignment, muscles have to work harder just to keep you upright, often leading to tension, aches, and fatigue. Strength training helps create a stronger support system, allowing you to move more efficiently in daily patterns. Many women notice they not only stand taller, but also feel more energetic throughout the day.

As posture improves, so often does confidence. Standing tall isn’t simply about appearance – it reflects strength, self-assurance and feeling comfortable in your body. When you feel strong and supported that confidence tends to show up in every area of life.

Improved Mobility

A stronger body moves more efficiently. Strength training helps maintain mobility, flexibility and independence as you age.

Getting Started

Three to four strength training sessions per week can make a significant difference. Focus on exercises that strengthen the whole body, including:

  • Squats
  • Rows
  • Deadlifts
  • Glute bridges
  • Resistance band exercises
  • Core strengthening movements

Start with a weight that feels manageable and focus on good technique. Consistency is far more important than lifting heavy weights! See a recent blog here on how you can get started if you’re unsure where to begin…

A Final Thought

Good posture is about creating a strong, resilient body that supports you through everyday life. As we move through midlife, strength training becomes one of the most valuable tools we have for maintaining mobility, reducing aches and pains, protecting our bones and preserving our independence.

It’s never too late to start! Small, consistent efforts will lead to meaningful improvements in how you move, feel and carry yourself. Remember that every workout is an investment in your long-term wellbeing.

My Own Strength Training Journey & Why It’s A Non-Negotiable

Fitness has been part of my DNA since before I can remember – growing up, I was always on the move. Whether it was running, gymnastics, hockey or simply being active outdoors, exercise never felt like something I had to do – it was something I genuinely loved. Looking back, movement gave me confidence and a sense of achievement long before I understood the physical and mental benefits it brought! As I got older, my relationship with fitness evolved. What started as a love of sport became a fascination with how exercise (particularly strength training) can make us feel. Not just physically stronger but more capable and resilient in everyday life. I first discovered weight training with Body Pump, a Les Mills class, in the late 90s and it really was my introduction to Strength. Over the years, I’ve seen fitness trends come and go, but one thing has remained constant which is my belief in the power of strength training for longevity.

Cardio vs weights

For many of us in our 20s and indeed 30s our fitness routine was very cardio driven. Endless time spent on a treadmill, in a spin studio or pounding the pavements. Whilst I still love running I have found that the ratio has very much swayed in favour of strength training now and in my 25+ years of personal training I’ve always worked with my clients to share this way of exercising and reinforcing the benefits. 

So how do I see the two compared side by side? Cardio exercise such as running, walking, cycling, swimming etc. is fantastic for your heart, lungs and overall fitness. It improves stamina, boosts mood and supports calorie burn, which is why I always include it in my Friday HIIT class – it’s a brilliant way to get your body moving and your energy up. I also think it is hard to beat for head space and endorphins.

Weights on the other hand bring a different and more long-term set of benefits. Resistance training helps build and maintain lean muscle, which is essential for a healthy metabolism, strength, posture and staying capable as we age. It also plays a key role in protecting bone density and can help regulate stress levels, supporting better sleep and recovery after training. The reason I lean so strongly towards weight training is because of what it offers that cardio alone can’t fully replace. 

Cardio improves fitness, but strength training is what keeps you strong and stable – it’s the difference between being fit and being functionally strong. That’s why in my HIIT sessions you’ll always see resistance-based work woven in – it’s important to build both fitness and strength in the same workout.

Functional freedom

As my knowledge of fitness and strength training in particular has evolved, so has the way I experience my body as I’ve moved through different stages of life. Consistently incorporating strength training over many years has allowed me to navigate those changes without focusing on what my body can’t do. Instead, I notice how supported I feel in everyday movement. 

This doesn’t mean you needed to have started years ago. In fact, now is as good a time as ever! Whether it’s managing niggles more easily, walking up the stairs without thinking twice, or feeling less tired and more energised overall, strength training helps create a sense of functional freedom – the ability to move through life feeling capable, supported and confident in your body.

The mental shift

One of the most overlooked benefits of strength training is the impact it has on your mind. In midlife especially, it becomes so much more than a physical practice. Many of us don’t expect how much clearer, calmer and more balanced they start to feel mentally. There’s something about challenging your body and lifting heavier as you get stronger that is incredibly motivating and empowering. It also really gives you a focus that I don’t find with running. You might start a workout with a busy mind – lists, decisions, responsibilities… But you’ll leave feeling like things have shifted back into place. You have to be present when you are lifting weights and paying attention to what your body is doing in the moment. You never regret a strength workout!!

A final thought

I genuinely feel stronger and more powerful now at 54 than I ever did in my 30s! And I feel that in midlife this is so key to how we feel day to day. Ruling out endless cardio sessions and replacing it with functional and intentional strength training has honestly changed the way my body responds and how I feel. Instead of dreading my workouts they are a part of my lifestyle now and a habit that I won’t stop. You don’t need to aim for perfection, you need to remember it is not a competition or a race. It is showing up for yourself and staying stronger for the future.

5 Surprising Facts About Protein!

Protein is one of the most talked about nutrients in health and fitness but there’s still so many facts we may not know about it. One of the biggest myths is that you need to live on protein shakes or eat excessive amounts of protein to feel the benefits. From helping us to stay fuller for longer, to supporting muscle strength, energy and recovery as we age, protein does far more than simply “build muscle”.

Here are some surprising facts you may not know:

1. More protein isn’t always “better”

Your body can only use a certain amount of protein at a time to build and repair muscle. Rather than saving it all for one big high-protein dinner, you’ll generally get more benefit by spreading your protein intake throughout the day.

An ideal target:

  • ~20–40g protein per meal
  • 3–5 protein-containing meals/snacks daily

2. Vegetables contain more protein than people expect!

Plant protein is a powerful tool for muscle growth. Protein-rich foods like lentils, edamame beans and peas can make a meaningful contribution to your daily intake, helping support muscle repair and recovery.

Examples:

  • 1 cup lentils: ~18g
  • 1 cup edamame beans: ~17g
  • 1 cup peas: ~8g

3. Protein helps you stay full for longer than carbs or fat

You might notice that a protein-rich meal keeps you satisfied for hours. Compared with carbs or fat, protein tends to have the biggest impact on fullness. It slows digestion and influences hormones that help regulate appetite. Meals and snacks like eggs, Greek yoghurt and chicken salads will leave you feeling fuller for longer in comparison to a breakfast of plain toast or cereal on its own. This also helps reduce mindless snacking.

4. You don’t need to stress about “complete” proteins

A common myth is that every meal needs to contain a “complete protein.” While animal-based foods naturally provide all the essential amino acids (building blocks of protein), most people eating a varied plant-based diet can easily meet their needs without carefully combining foods at every meal.

Over the course of a day, foods naturally complement each other. Examples include:

  • Rice and beans
  • Hummus and pita
  • Tofu and grains
  • Lentils and quinoa

5. Protein becomes even more important as you age

While strength training is one of the best ways to maintain muscle in midlife, research shows nutrition matters just as much. For women particularly, our muscle mass declines from age 35 onwards and especially post menopause. Without enough protein in our diets our bodies don’t have the capacity to repair and maintain muscle, which is often why you might feel you’re exercising consistently but not feeling stronger from your workout. Boosting protein intake doesn’t have to feel restrictive or complicated. It’s about building balanced meals that fuel your body properly, support your workouts and help you feel stronger and more satisfied day to day.

Five Of The Best Daily Protein Foods

EVERYONE talks about protein but do you know how much protein is in the foods you eat? As a guideline the general protein recommendation for adults is to have 0.8 grams of protein per kg of body weight with more active women (especially those lifting weights) having 1-1.2 g per kg body weight (65-78g of protein for a 65kg woman). 

Small consistent habits throughout the day work brilliantly – you don’t need to overcomplicate your diet. Use the table below as a general guide, this easily puts you into the 100g+ protein range without supplements.

EggsGreek YoghurtChicken BreastSalmonLentils
~6–7g protein per egg~15–20g protein per serving~30g protein per 100g cooked~22–25g protein per 100g~18g protein per cooked cup

Protein and Recovery

We often talk about the importance of strength training and recovery and your protein intake helps repair your muscles too. Without including enough protein, this can leave you feeling sore, fatigued and slower to recover between workouts. It’s not always about training harder – it’s about supporting the body better before and afterwards. Alongside sleep, hydration and rest, eating enough protein can really help improve recovery, maintain lean muscle and support steady progress over time.

What to Eat Before and After Strength Training

One question I’m often asked is whether you need to eat before and after workouts. It really comes down to personal preference here but fuelling your body properly does make a big difference to both energy levels and muscle recovery. If you’re training first thing in the morning, you don’t usually need a huge meal beforehand. Something small is enough to give you energy for your workout without feeling too heavy. After training, it’s important to refuel with both protein and carbs to support recovery and repair muscles plus give you energy for the day ahead – aiming for a balanced meal within a couple of hours is a good habit to build.

Before Strength Training

Some ideas:

  • A banana (I always have one before training) plus my coffee
  • Small bowl of overnight oats
  • Greek yoghurt and berries

After Strength Training

Depending on the time of day you train, simple post-workout meals could include:

  • Eggs on toast
  • Smashed avocado and eggs
  • Salad and protein or grains and protein 

A Final Thought

When it comes to protein, it’s easy to get caught up in trends, supplements and conflicting advice. It really is much simpler than that: protein is a key part of staying strong, healthy and active as we age. Small tweaks to your balanced diet really can make a huge difference in the long term.
