Attach a VECTOR resistance band torso strap to your trunk (start over the right shoulder), turn left wrapping the strap around your back then across the front of your body. Stop when you are facing the resistance that will be placed over the leg. Then attach a leg accessory strap just above the knee on the left leg. Pick up the foot of the resisted leg and thrust it back—extending your knee through the resistance and driving your heel towards the ground (even though the heel will be hovering just above the ground).

Repeat on both sides for 3 – 8 reps. Manipulating the tempo of this exercise helps establish foundational posture stability with minimal coaching because the resistance maximizes activation.
