Get your grip right and reap the benefits
Wide-grip Vs. close-grip.
You can add variety to your exercises by alternating the type of grip that you use. This way, you’ll keep your body guessing and it will always react well to the training. Two main types of grip are wide and close-grips.
Barbell Curl- A wide-grip will hit the outer side of the bicep, whereas a close-grip will develop more of a peak on your bicep.
Shurgs- A wide-grip will concentrate on the outer area of the trapezius, a close-grip will touch on the inner trapezius and the rhomboid muscles.
Bench Press- A wide-grip is used to work the outer pectorals, a regular grip will concentrate on triceps and pecs equally, and a close-grip will touch on your triceps a bit more.
