This total body workout is devoted to two types of exercises that you might despise because they're so tough,but man, they are effective at strengthening your thighs, or butt,core, and abs! It's just six moves, and done for 30 seconds each,for a total of three minutes. So you can enact this short workout once, or repeat it a few times for a longer workout, and whatever you have time for,or before your muscles give out - whichever comes first.
