I'm Renee Byrd with LIVESTRONG.COM, here to talk about how to build a strong core for back hand springs, and tucks. When really trying to learn a back hand spring or back tuck, the best thing to do, is make sure you're physically conditioned. And that includes having a very strong core. I'm going to show you a couple of exercises that you can do at home. To make sure that your core is strong enough the next time you go out to do your back hand spring or back tuck. Performing a proper sit-up. This is a sit-up. Now, when doing a sit-up, you want to make sure that you're breathing in and out , make sure you always exhale, going to the top, inhale, going to the bottom. Again, make sure that your elbows are out of your eyesight. So that you don't find yourself pulling with your neck. Side V-up exercises. The second exercise I'm going to show you, is a side V-up. So, you're going to lay on your side. You're going to take your bottom hand and lay it out, lay your arm out in front of you. You're going to take your top arm and you're going to make sure that your shoulder touches the back. Once your shoulder touches, you're going to reach up, touch your toes. Again, I'm Renee Byrd with LIVESTRONG.COM, we just talked about how to build a strong core for back hand springs and back tucks.
