Sport is essential for health and well-being - but it only helps to a limited extent against cellulite alone.
The reason:
Physical training has a particular effect on the deeper, subcutaneous fat tissue.
However, cellulite develops directly beneath the skin's surface, in a layer that is hardly affected by exercise.
Even a healthy diet or weight loss does not necessarily lead to smoother skin. Even very athletic people often struggle with cellulite, regardless of their weight or fitness level.
