Prepare into your handstand.
As you lower your hands to the floor, bend your knee (the foot you're standing on). When your hands touch, push off of your bent leg. Your power leg should squeeze up to meet your airborne leg.
To balancehave your fingers spread wide on the floor to increase your base. Push out of your shoulders. Stack your hips over your shoulders over your hands. Squeeze your abs, butt and legs.
Here's everything combined :) also, avoid flinging your first leg. (ran out of space on other slide...). If you're uncomfortable doing these in case you go over, practice against a wall :) good luck!
