Overall, the data indicate that grip widths > 100 % of shoulder (acromial) width produce superior but
similar pectoralis major sternocostal head muscle activity.
Not exact matches
Also, in the study, activation of the anterior deltoids and
pectoralis major was
similar between dumbbell bench presses and barbell bench presses, but stimulation of the triceps brachii was lower.
The military press uses
similar muscles to the bench press but as you are stood vertically it virtually removes the
pectoralis muscles from the movement which then makes it weaker as a strength exercise.
Studies investigating multi joint exercises (such as the bench press) and single joint exercises (such as the dumbbell fly, pec deck machine, and bent - forward cable cross-over) have generally found
similar levels of
pectoralis major EMG amplitude across all exercises, which suggests that either type of exercise can be used to good effect (Welsch et al. 2005; Rocha - Junior 2007; Shanke 2012).
Overall, research indicates that the free - weight and machine bench press produce very
similar levels of
pectoralis major EMG amplitude and therefore either will train the muscle effectively.
Specifically, the barbell bench press performed on a Swiss ball displays either
similar (Goodman et al. 2008) or inferior (Saeterbakken & Fimland, 2013)
pectoralis major EMG amplitudes, compared to performing the bench press on a stable bench.
