Stretch marks are a natural phenomenon that nonetheless affects many people’s confidence. They result from a localised loss of elasticity in the dermis. To prevent them from appearing, the key is to keep your skin as firm and toned as possible. But where does sport fit in? Could it actually help us avoid the dreaded stretch marks?
The preventive benefits of sport
The benefits of physical activity on the body as a whole are undeniable. But how exactly does sport help prevent (or even reduce) stretch marks?
1- It helps maintain a healthy weight
As we know, sudden and rapid weight gain is one of the main causes of stretch marks. When we put on weight quickly, the skin stretches too abruptly, collagen fibres tear, and stretch marks appear. Regular physical activity helps stabilise your weight and avoid the fluctuations that encourage stretch marks on the thighs, hips, stomach, and sometimes arms and legs.
2- It helps prevent skin ageing
As we age, the epidermis (the outer layer of skin) tends to dry out and thicken, while the dermis (the deeper layer) thins and loses its elasticity — leading to visible skin ageing. However, physical activity appears to have a beneficial effect on maintaining the skin’s collagen content. A protein produced by muscle cells is thought to stimulate collagen production. Since collagen is directly linked to the appearance of stretch marks, that’s all the motivation you need to get moving!
3- It boosts blood and lymphatic circulation
Sport is beneficial for the circulation of blood and lymph through our veins and arteries. A healthy veno-lymphatic system produces two positive effects on the skin:
- Good oxygenation and nourishment of tissues, thanks to proper blood flow
- Effective elimination of waste, thanks to optimal lymphatic flow
Skin that is well hydrated, oxygenated and properly cleansed of toxins is healthy skin — and far less likely to develop stretch marks!
4- It lowers cortisol levels
It’s well known that sport is good for your mood and has a positive effect on anxiety, stress and low spirits. Why? Because it boosts the production of endorphins and dopamine — the so-called “feel-good hormones” — at the expense of cortisol, the stress hormone. Great news, since cortisol plays a significant role in the development of stretch marks — it’s actually one of the main culprits!
The downsides of sport
So is sport the sworn enemy of stretch marks? At first glance, you might think so. But it’s more nuanced than that — not all sport is created equal! Some athletes notice stretch marks appearing over time on their arms, chest, thighs or calves. The culprit: sudden and rapid muscle mass gain.
We tend to associate stretch marks with weight gain, but far less so with muscle gain. Yet the effect is the same: increased volume, tearing of subcutaneous collagen fibres, and a whole lot of stripes!
The sports most likely to cause this: excessive weightlifting, high-impact sports (sprinting, crossfit, ball sports, high-level gymnastics) or those that target a specific muscle group (rowing, weightlifting, tennis).
So if you’re a fan of these types of activities, one golden rule: take it gradually and make sure you stay well hydrated — both by drinking enough and by taking care of your skin!
Stretch marks: the best sports to choose
It is generally recommended to favour gentler activities over high-impact sports — ones that allow you to build muscle without putting your skin under stress or triggering stretch marks. These activities let you enjoy all the skin benefits of exercise while improving your overall tone!
- Swimming and water sports in general: great for everything — slimming, anti-cellulite, anti-water retention, and skin-firming (thanks to the natural massaging effect of water). Swimming builds muscle mass evenly and gently, with no risk of encouraging stretch marks.
- Barre: inspired by classical dance, it works all the deep muscles without hypertrophying them, and develops overall body flexibility — skin included!
- Pilates: a full-body muscle-strengthening practice that helps prevent stretch marks from appearing, even in prone areas such as the lower back and chest.
- Nordic walking: a brisk walk using poles, focused on breathing rhythm and range of motion. Zero strain, guaranteed wellbeing, and no risk of stretch marks!
One final tip: to complement the effects of sport on stretch marks, a preventive and smoothing routine such as our Stretch Mark Pack is highly recommended!
