: Back attack action today with the boys at #worldsgymSD Two of my favorite exercises on a pull movement day. Muscle-ups and heavy eccentric biceps curls. Muscle-ups are a fantastic plyometric exercise that activates the latissimus dorsi, biceps and core. If you can do a pull up then you can execute a muscle-up. Incorporate a "kipping"motion as you generate momentum form the pull up. Pull your chest past the bar and use your core and legs to thrust the rest of your body up and over the bar.
