The single-leg dumbbell RDL passback is an accessory exercise to improve hip stability and balance.
 
Stand on one leg with the knee slightly bent and a single dumbbell in the hand opposite the support leg (contralateral). Hinge at the hip to lean forward while bringing the back leg up, maintaining an approximately straight line along the trunk and lifted leg, trying to prevent any rotation.
 
Bring the weight as low toward the floor as possible without your back rounding and hold. In this position, swing the arms sideways to pass the weight from hand to hand while maintaining balance and control of the position. The more quickly you pass the weight, and the farther out to the sides you allow it to travel, the more challenging.
 
Purpose
The single-leg RDL passback improves hip stability and balance. 
 
Programming
Single-leg RDL passbacks should be performed at the end of the workout sets of 8-15 on each side. Weight should not exceed what the athlete can use with stable, balanced, controlled reps. Light weight with stability and control is more effective than heavy weight without.
 
Variations
The athlete can stand on an air pillow or cushion to increase the balance challenge.
