I can hardly do a bridge, so I think kip-ups are a ways out. Haha. Been doing cartwheels since gradeschool though. One out of four ain't bad right? The other stuff should be doable though. Just need to find some place to practice besides the hardwood in my living room. lol.
Thanks for the video as well. Breaking it all down is incredibly helpful!
You can train up to being able to perform a full bridge, even if you have prior back injuries. I've been doing some preliminary exercises in preparations for attempting half bridges.
I read a book called "Convict Conditioning" by Paul "Coach" Wade, who talks about bodyweight training as opposed to straight weight training. The premise is to use your own body weight in exercise movements that the body uses naturally to increase strength. Bridging is one of the "Big Six" exercises, and there are 9 other preliminary exercises to work at prior to attempting a full bridge. My lower back is torn up from years of abuse of military training and other factors, but since I began the exercises in this book, I've seen much improvement overall in how I move and how I feel.
Might want to check it out.
