Do you think it matters so much if you just do 15 min (because you don’t want to make more) instead of 45?

Well its not that I dont want to do it I just dont have time for it. I am always busy so I don't have time to do something for 45 minutes. At least I'm doing it for 15 minutes instead of none at all.

No because if you take a little time for your body to take care of it that’s all that matters cuz ur be healthy but ur not pushing ur self in an unhealthy way
