Everyday, I do push up and use power twister for two techiniques (U shape upand down). Day by day, I like power twister very much. So can I replace my push up routine with power twister? For example, I do push up 10 times for 1 set and use power twister 10 times for 2 set. But I will use power twister 10 times for 3 set instead of doing push up. Can have something disadvantages? Thank you.
