The only people that would benefit from

The pull-up only involves your bodyweight, but it’s one of the best tests of upper-body, grip, and core strength. Every man should learn how to master it. Not a pull-up pro yet? Don’t worry. Here are 10 tips that will turn you into one. 1. Crush the bar The benefit: Securing your grip allows you to get a proper muscle contraction in your upper back and shoulders. This makes you stronger and makes it easier to hoist your weight up to the bar. Do it: Stand on a box or bench so your hands can reach the pull-up bar. Grab the bar with your hands slightly more than shoulder-width apart. Squeeze the bar three times. On the last squeeze, pretend as though you’re trying to crush the bar in your hands. Maintain this grip throughout the entire movement.
