Hoe groter de afstand, hoe minder nadruk op de triceps en hoe meer nadruk op de borst.

FIGURE 1. Electromyographic activity from the pectoralis major and triceps brachii was examined during push-ups performed from each of 3 hand positions: shoulder width (SW) base (A), wide base (WB) (B), and narrow base (NB) (C) hand positions. In the SW hand position, subjects positioned their middle finger at the end point of a plumb line hung from the edge of their deltoid. In the WB hand position, subjects positioned their hands 20 cm laterally from the SW position. In the NB hand position, subjects placed their hands together under the center of their sternum, forming a diamond shape between their thumbs and index fingers

FIGURE 4.Mean normalized electromyographic (EMG) activity in the pectoralis major and triceps brachii muscles obtained during push-ups performed from the shoulder width, wide base, and narrow base hand positions. The EMG activity is significantly greater in the narrow base hand position than the wide base hand position in both the pectoralis major (p = 0.005) and triceps brachii (p = 0.026) muscles
