Mixed-Grip Pull Up
Been doing the mixed-grip pull up for the last couple of weeks now, and it's a great exercise not only for the back and biceps but also for the core as well. How do I know? Cause I'm sore as heck. From the June 2006 issue of Men's Health: The mixed-grip pull up is the ultimate two-in-one muscle builder for beach-ready biceps and a V-shaped back. This variation also helps define the midsection. By using an overhand grip with one hand and an underhand grip with the other, you add a rotational component to the exercise. Your core musculature is forced to contract hard to stabilize your torso so your body stays straight throughout the move.
Grab a chinup bar with an alternating grip - one palm facing you (underhand grip), the other facing forward (overhand grip). Keeping your abs tight, pull yourself up until your chest is even with the bar. Pause, then lower yourself. Do 10 repetitions with your hands in this position, then, on your next set, do the reverse. Do up to four sets.
