How to Do a Back Flip More Than One Time

1). Master the single back flip (a 360° rotation) before moving on to double back flips (720° rotations) or more flips between which you land. Mastery means that you consistently execute the single back flip correctly, not just that you happen to do so occasionally.
2). Practice double back flips on a trampoline or off of a diving board into a pool. Even though you will not have a springing surface when you do back flips off the ground, practicing with one will teach you to stay tucked for consecutive rotations. Practice keeping your body in line when tucked, rather than tilting to one side or the other.
3). Practice your second bounce if you are attempting to do multiple back flips between which you land. Land with bended needs to soften the impact of the first back flip. Absorb the landing and bounce back up by pushing yourself off the ground into the air. This drill will help you to gain momentum for the second back flip and make consecutive back flips in one fluid motion.
4). Ask an experienced gymnast or spotter to assist you during your first attempts on the ground. A spotter can intervene to help your body complete rotations. Ask the spotter to observe any mid-air techniques that require improvement, such as your body losing its tight tuck position during the second rotation. Wait until you have mastered the basic techniques with a spotter before you attempt the trick on your own.
