Okay, you probably did know about some of these, but for the general gym goer, a few of them are not all that well known. Some of them are bodyweight only, and some require equipment.
And, several are tricky to perform and need a little practice and perhaps experience in resistance exercise.
Another great exercise is the 8-count bodybuilder. All you need is yourself and a little floor space:
1) begin with a body weight squat (hips down and weight in your heels)
jump straight up
2) drop your hands to the ground and kick your legs out to plank position
3) lower down to a pushup
4) explode back upward into plank (try to make your hands leave the floor)
5) kick your legs out to form an x while maintaining plank position
6) bring your legs back in
7) pull your feet up under your chest
Will, yes a burpee variant, but very challenging.
Thanks.
