If you want a V-shaped torso, you must do pullups and chinups. They build width because they target your latissimus dorsi (a.k.a. lats), the large back muscles that wrap around the sides of the upper body just below the arms. These muscles are the ones that give the torso a wider, flared shape, and can make you appear slimmer even if you haven’t lost an inch around your middle.
Below is a list of variations of this classic back exercise from easiest to hardest. As you pull your chest to the bar during each rep, think about pulling your shoulder blades toward your back pockets. This will force you to use your upper-back muscles—as opposed to your biceps—to perform the move.
For each rep of this back exercise, you’ll start in a dead hang and then pull your chest to the bar.
CHINUP: Grab the bar with a shoulder-width underhand grip.
NEUTRAL-GRIP PULLUP: Grab the parallel handles of a chinup station so that your palms are facings each other.
MIXED GRIP CHINUP: Placing your hands shoulder-width apart, use an underhand grip with one hand and an overhand grip with the other.
PULLUP: This is the same movement as a chinup except that you grab the bar with an overhand grip that’s slightly wider than shoulder width.
START-AND-STOP PULLUP: Perform a pullup, and then slowly lower halfway down to a dead hang. Pause, then pull your chest to the bar again. Pause, now lower all the way down to a dead hang. That’s 1 rep.
ISO PULLUP: Perform a pullup, but hold your chin above the bar for 10 to 15 seconds. You can do this for several reps or on the last rep of your last set ofpullups.
TOWEL PULLUP: Find your hand positions for a chinup, then drape a towel over each of those spots on the bar. Grab the ends of the towels so that your palms are facing each other. Grasping the towels engages more of your forearm muscles, improving your grip strength and endurance.
