How many pull ups and chin ups a day to develop really big lats??
No muscle development program should involve exercising the same muscle groups every day. This will only hamper efforts and prevent muscle growth. Pullups and chinups executed properly should be pretty difficult for most people. Add weights as necessary as you advance. I suggest only working these out no more than twice a week to see good development – more than this and you risk overtraining and lack of muscle growth. Personally, I do pullups no more than twice a week with a 25 pound weight, and I can’t do any more than 8-10 reps the first set. I see people going all over the place with pullups, flipping their legs up and using a lot of momentum. Legs should be completely stationary during the exercise, with abs contracted and back straight or with a slight arch. Elbows should come down to the sides as if you’re touching your sides with them. Chinups follow a similar movement. Also, muscle size is dependent on diet, so a caloric excess is needed in order to build muscle.
