What on earth? Why does the second rep go better than the first rep? And how can you take advantage of this phenomenon in the future.
Why This Happens
While there might be more than one reason, one probable factor is that - by the time you get to the second rep - your body “knows” how hard you have to pull to get that bar moving.
Among the Big Four - the squat, deadlift, press, and bench press - the deadlift is unique. It is the only lift of the four wherein you don’t support the weight of the bar before the lift starts. After all, it’s sitting on the floor. In the squat, press, and bench, you are supporting the bar before any movement starts, and as a result, you get to feel the weight of the bar compressing you before the real work begins. This gives your brain and body an opportunity to calibrate itself for the task ahead; it gives you a rough sense of how hard you have to drive the bar upward.
