Girls who run or do high intensity sports can sometimes feel âpuffierâ rather then leaner, even while getting fitter and stronger.
It doesnât automatically mean theyâve gained body fat.
Stress shows up as water retention and inflammation, and physical activity is a stress.
Running, Hyrox and other high intensity training create muscle damage, the body temporarily has to hold fluid around the trained tissue while repairing it.
Quite often we see with female athletes recovery isnât meeting the demand of the training. Poor sleep, back to back training sessions at high intensity and inadequate easy days can leave to body feeling persistently inflamed especially paired with under eating.
Sometimes adding in carbohydrates around your training reduces puffiness. Your body ainât broken itâs just under supported.
Body fat doesnât dramatically appear overnight, if weight, measurements, or appearance change quickly across a few days it is far more likely to be water, glycogen, inflammation, digestion or menstrual cycle fluctuations, and your nutrition not meeting the demands of your training session.
