Weightlifting is a form of exercise that allows you to selectively
develop muscular strength,
size, and endurance by exerting forces against weight based loads.
Bodybuilders use weight training to improve their body image by
developing their muscles for
size, shape, and symmetry regardless of any increase in strength for competition in bodybuilding contests; they train to maximize their
muscular size and
develop extremely low levels of body fat.
However, the level of muscle activation achieved during these variations does still seem to be too small to provide a beneficial training effect for
developing strength or
muscular size.
Indeed, in many cases it is likely that performing the push up without additional external load (such as elastic resistance) is unlikely to produce sufficient levels of pectoralis major EMG amplitude such that the exercise will help
develop muscular strength and
size.
However, the relative EMG amplitudes ranged between 20 — 40 % of MVIC, which is considered insufficient for effectively
developing strength and
muscular size.
