Stand on one foot. Hook the resistance bands to the single foot through the D rings on the left and right sides of the ankle strap, and connect the bands to the workout bar doubled through the holes under the workout bar and the D-rings on the ankle straps.
Maintaining the arch of your spine, lower your hands to the floor by pushing your hips back, extend a leg backwards to maintain balance. Return and repeat.
Add difficulty by triple, or quadruple the resistance bands through the holes under the workout bar and the D-rings on the ankle straps.
