Close Grip Chin-Ups - Phase 2 - Day 2 - Strength. A great exercise to finish the workout with. You get a great stretch in the lats & really work them hard, which will help give you that great V-taper. Posture is crucial during the movement. You should have a slight arch in your lower back, with your chin & chest up. Slowly raise yourself up by contracting the lats. Squeeze at the top of the movement before lowering yourself slowly down. This is generally a last exercise for the back & can be performed with a variety of grips including the reverse, neutral or underhand grips. Don'ts - Don't swing your body or your feet & use the momentum to get you up. Nick Jones - World Bodybuilding Champion & Zoran Lekic - Bodybuilder.
