You may be thinking,We just worked our legs and abs two days agoand you would be correct.

And thats the presence of load.

Thats different from day 19, where you performedbodyweight lower-body exerciseswith a HIIT-based, high-work, little-rest programming.

Reverse lunge to rotation

And be sure to really squeeze those glutes at the top of the movement for full muscle engagement.

Want a little extra work after the main set is done?
