Exercise selection for muscle growth: 6 debates, 1 real variable

You stress about six training decisions every week. The evidence says five of them produce zero or near-zero effect on muscle growth. The sixth produces two to three times the regional difference — and most people never think about it.

Bench press days leave a record. The plates on the bar carry a number, logged in your phone, waiting to be beaten next week. Push-up days leave only a tally, and the higher it climbs, the less the set seems to weigh. So the push-ups vs bench press question often turns into private arithmetic, a hunt for how many floor reps one bar rep is worth, with nothing to convert, because in your head a push-up weighs nothing. The floor knows otherwise. At the peak of a regular push-up, fit young adults pressed about 64% of their body weight through their hands, and dropping to the knees brought it to about 49%. If you weigh 80 kilos (176 lb), that comes to roughly 51 kilos of you on your palms every rep, by FitChef's arithmetic, a figure that moves with your own weight.

The romanian deadlift and the stiff leg deadlift look nearly identical. You hinge, you grip, you lower, you stand. The only visible difference — a slight bend in the knee — seems like a footnote, not a decision that changes anything.
