HOW: Begin this exercise standing with a slider resting under one foot. From here, step out into a lateral lunge with the outside leg bending that knee. From that lateral lunge position, pull the leg with the foot resting on the slider up to meet the other foot as you return to a standing position.
FEEL: You should feel the muscles of the thigh and adductor working the most as you perform this exercise.
COMPENSATION: Avoid taking too far of a step out to the side. Take a big enough step where you can control sliding the outside foot on the slider up to meet the other foot.
