But running produces muscles.

So remember, your massage doesn't work. If you want to stretch, you need to stretch the front and rear thighs and calves, otherwise there will be muscle accumulation.

It seems that you have been running for a long time and practicing for many days.

Your parents walk for an hour and consume more calories than you do.

If you want to lose weight, don't walk too fast. If you can run, you must be good at running. Pay attention to stretching, it must be better than them.

And in terms of diet, they may eat less than you, or absorb less than you, so their legs will be thin.
