Warrior III Abs
To do Warrior III Abs, set up in the Warrior III position, balanced on one leg with your raised leg driving back toward the wall behind you and your hips square to the ground. Reach your hands out overhead, reaching toward the wall in front of you.
Staying hinged over, crunch the knee of your raised leg in toward your chest as you pull your elbows in toward your knee. Really use your abs to crunch your elbows toward your knee. Do not stand up though as you crunch.
Then extend back out. Stay balanced on your standing leg and try to stay hinged over as you tuck and extend. Do not touch your toe down unless needed to stay balanced. Beginners may tap it down between reps.
