Similar to 50/50 push-ups, a negative push-up helps you strengthen the muscles used in the traditional move, but with greater intensity. A negative push-up focuses solely on the downward (aka eccentric) movement of the exercise, but done at a much slower pace. An easy way to envision the exercise is to think of it like doing one-half of a full push-up while counting to six. By putting all the load on the eccentric movement, you focus on strengthening the muscle and helping it learn to contract in the move.
