The effect of grip width and forearm pronation/supination on upper body muscles while performing the flat bench-press exercise was also explored and it was found that small changes in muscle activity were associated with changes in grip width ( Lehman, 2005). In addition, EMG of the shoulder and trunk muscles during different variations of the lat pull down exercise was investigated ( Lusk, Hale & Russell, 2005 Signorile, Zink & Szwed, 2002), showing that maximal activation of the latissimus dorsi was obtained when performing the exercise with an anterior wide grip. For instance, the effect of feet position on the electromyographic (EMG) activity of quadriceps muscles has been previously reported ( Boyden, Kingman & Dyson, 2000 Signorile, Kwiatkowski & Caruso, 1995), as well as the effect of stance width on the activity of the gluteus maximus during a back squat ( Paoli, Marcolin & Petrone, 2009). These training approaches have been investigated in both lower and upper body exercises which target specific muscle groups. Therefore, to maximize muscle hypertrophy, bodybuilders construct training programs which involve exercises isolating specific muscles with different exercise variants or different ranges of movement, with the aim to increase muscle activity. ![]() In strength athletes such as bodybuilders, resistance training plays a key role as it induces muscle hypertrophy. Resistance training has fundamental importance in improving athletic performance as it allows the increase of muscular strength, power and speed ( Kraemer & Ratamess, 2004).
