For a reverse-grip lat pulldown, use an underhand grip and your palms facing your body.
For a close grip, your hands should be positioned shoulder-width apart.
Do not bounce up and down to get the bar up and down, and do NOT perform this exercise if you have back issues!
Caution: Do not choose a weight that is too heavy. This can result in straining your lower back.
Stand straight up with your feet shoulder-width apart and holding dumbbells.
Jump into a wide squat position and touch the floor (or close to the floor) with one arm extended towards the floor.
*Try to keep your chest lifted while you do this.
