Medicine Ball Rollout: Same as using an ab wheel thingy, but your hands walk the ball out, one at a time. I just figured this one out (not saying I invented it though), but I can't do it much because of a bumb right elbow.
Double Depth Burpee: I love burpee variations. Get two blocks (stack of books, cinder blocks, whatever) and place them at your wide pushup "grip". Get a box (saw horse, chair, etc) and place it a foot or two in front of the blocks.
Stand in between the blocks, squat down, place hands on blocks, kick back and do an explosive pushup, landing your hands in a narrow or diamond grip placement on the floor. Explode up from this grip, tucking your legs in and under you.
Jump up on to the box in front of you, squating all the way down on top. Jump as high as you can up and backwards to land back in between the blocks. Squat down and repeat.
Walking pullup: This one requires a long bar of some sort (I hang from the exposed floor of the loft in my barn). Take a shoulder width grip (or whatever grip you prefer), pull up. At the top, shift your hands over one at a time and then lower so that you are next to where you started from. Pullup again and shift back to the start.
Switching grip plyometric pullup: Start with a wide grip, do an explosive pullup. At the apex of the "jump", release the bar and slide your hands in close to decend with a narrow grip. Explode up with the narrow grip and shift out to a wide grip. Repeat.
This last one I don't know what to call: You need to have to parrallel bars. I currently make use of the exposed rafters of my unfinished deck. Do an explosive chinup (palms towards you) FORWARDS and catch the bar in front of you palms facing away. Lower, explode up and BACKWARDS, catching the starting bar with the chinup grip again. Repeat.
I love variations of common things.
Take it easy,
