WIDE GRIP STRICT PULL UPS
Strict pull ups are an excellent exercise for building strength in general. Widen your grip and you make the movement even harder. This will force your traps, delts, lats, tris, teres major and core to work even more and strengthen your back. If you struggle with strict pull ups, then check out the video below.
This video shows progression exercises to help you build up to strict pull ups. If you are already fairly confident with this strict movement then simply add it into your training when you want to specifically develop your back strength. For pure strength, work in sets of no more than five reps, and you want to be close to failure by the last rep. Add a weight vest if necessary. If your goal is more towards hypertrophy, work in sets of 8-12 reps and maintain a high intensity with short rest times between working sets.
If you can manage three sets of ten full wide grip pull ups (back to a neutral hanging position with every rep) then that’s a very respectable milestone in you training and back strength.
