Electromyographic validation of the deltoideus (anterior portion) and pectoralis major (clavicular portion) muscles in pull-over exercises

The electromyographic activity of the deltoideus (anterior portion) and pectoralis major (clavicular portion) muscles was analyzed in 24 male volunteers in two different modalities of pull-over exercises. The PMC activity varied from weak to moderate in both modalities, while the DA activity was moderate in the pull-over and strong in the pull-over with bent arms exercises.
