When we talk about exercise, we tend to focus on the physical benefits — stronger muscles, a healthier heart, improved fitness, weight management and stronger bones. But for me, one of the most important reasons to exercise is simply how it makes us feel. I’ve always believed that movement is as important for our mental and emotional wellbeing as it is for our physical health.
When we exercise, all sorts of interesting things happen in the brain. Physical activity influences neurotransmitters and other chemical messengers involved in mood, motivation and wellbeing, including serotonin, dopamine and noradrenaline. Exercise can also increase endorphin activity, which is one reason we can feel calmer or more positive after moving our bodies. You don’t necessarily need an hour-long workout to notice a difference. Sometimes a brisk walk, a cycle ride, twenty minutes of weights or a yoga class is enough to shift how we feel. I often think of exercise as pressing a little reset button.
Exercise can also be a wonderful way of managing stress. Modern life can keep us permanently switched on — answering messages, rushing between commitments, worrying, planning and thinking. Movement gives all that mental energy somewhere to go. Regular physical activity is associated with improvements in stress, anxiety and overall wellbeing. I particularly love combining exercise with breathwork, yoga and relaxation because we’re not simply asking the body to work; we’re also teaching it how to recover. And recovery is part of fitness too.
One of my favourite psychological benefits of exercise is the confidence it can create. Someone might walk into a gym thinking, I’m not very fit, I’m too old to start, I’m not strong. Then one day they lift a weight they couldn’t lift before. They cycle a little further. They complete their first class. They realise they can squat, push, pull and move with more confidence. Gradually, that internal conversation begins to change from I can’t do this to I can do this. That sense of achievement can extend far beyond the gym. Exercise gives us repeated opportunities to experience progress, perseverance and mastery.
Movement can also give a busy mind somewhere to focus. When I’m practising yoga, lifting weights or cycling, I’m much more aware of my breathing, muscles, posture and surroundings. Instead of living entirely inside my thoughts, I’m back inside my body. For people with very busy minds, that can be incredibly valuable. It’s one of the reasons I don’t see yoga, breathwork and fitness as completely separate disciplines — they can complement each other beautifully.
Regular physical activity can also support better sleep, and sleep affects almost everything — our mood, concentration, appetite, energy and ability to cope with stress. It can become a lovely cycle: move more, sleep better, have more energy and feel more able to move again. Exercise isn’t a cure for every sleep or mental-health problem, of course, and sometimes professional support is needed, but movement can be a powerful part of looking after ourselves.
Perhaps the most important message I give people is that you don’t have to exercise in a particular way for it to count. You might love lifting weights, swimming, cycling, dancing, yoga or simply walking. Fitness shouldn’t be punishment for something you’ve eaten, and it shouldn’t be something you dread all week. I want people to discover movement that leaves them thinking, I feel better than I did before I started.
Because exercise isn’t simply about creating a smaller body. It’s about creating a stronger body, a calmer mind, greater confidence and a better quality of life. And those, for me, are some of the best reasons to move.
