I was practicing hopping up with my friend, who is a gymnast, and was able to get up on her first outing. No wonder I couldn't stand up! I had a tough enough time getting my front foot through my arms just on the ground. Here's some stuff I learned:
When pushing up with your arms, don't peel your body up starting with your chest. You must get your butt up, kind of like making an A frame. This gives you momentum. We also found that pushing up with your hands by your ribs instead of by your shoulders works better. Next, you have to be able to curl your back, or pull your chest towards your pelvis. This puts you in the right position to move your front foot through your arms. Problem is, I have a hard time doing that. I also can't touch my fingers to my toes. So I'm going to do a stretch routine for 30 minutes every night.
