Performing the: A Step-by-Step Tutorial Smith One Leg Deadlift
Stand on one leg, let's say the right one, and slightly bend your knee while reaching out and grabbing the bar with both hands.
Lower your torso and lift your left leg behind you, keeping it straight and in line with your torso, until both are parallel to the floor, while the bar goes down guided by the machine.
Use your right leg to push your body back up to the starting position, while lowering your left leg back to the floor.
Repeat this motion for the desired number of repetitions, then switch legs and perform the same action for an equal number of repetitions.
