Besides pull ups, all of my lifting is done in a very low rep range. For OHP, bench press, and squats I never go above 3 reps. Once I can get a set of 3 without too much trouble, I move up the weight. Then I do heavy doubles or even singles until I am strong enough to get a set of 3, ad infinitum. But IST tells me I need to be doing more volume. What gives? Is there something wrong with low rep range training? I’m going to stick with it until my linear progression slows.
