Exercising with my daughter every day

My daughter's belly fat these days... haha

I'm in upper grades, but only my belly fat is showing.

I also feel stressed and think I am not moving enough.

These days, I want to do home workouts together at home.

I'm trying to work harder too, using my daughter as an excuse, haha.

But why am I the only one who’s sick? Haha

Even after sleeping and waking up, my daughter is perfectly fine.

Only my leg is cramping and hurting ㅠㅠ

Is it because of my age?ㅠㅠㅋㅋㅋ
