Back to Back is one of the basic Acro Yoga or Partner Acrobatics standing poses with intermediate difficulty.
Tips for a Base
Make sure your grip is really elbow to elbow, not higher or lower, so the flyer can really lean to your bent arms and don’t need to press her or himself all the way up. The more you bend your knees, the easier for the flyer to jump up. After jump, give the flyer enough time to get into the inverted position before you stand up straight.
Tips for a Flyer
Before you jump, be as closer to the base as you can. It’ll be more easier for the base to stay in balance. Jump as closer to the inverted position as you can, so you don’t need to press the rest of the motion.
