Muscle activation. Push Ups and Bench Press mainly do the same thing â they target chest, front shoulders, triceps and lats in a pushing motion. However, when doing Bench Press the weight moves and the upper body is stabilised on a bench, which makes it easier to focus on your chest and push more weight. In Push Ups the body is moving instead, so the exercise involves more joint motion and importantly - more core activation for stabilisation.
