Arnold Curls improve the shape of the biceps and also help to add mass. The exercise can be done on either a flat weight bench or an inclined weight bench. The use of the bench stabilizes the body, allowing the exerciser to concentrate on moving through the full range of motion to stretch out the muscle. To get the most benefit from the exercise, the arms are curled at the same time.
The overhead press is a shoulder-isolation exercise. The knees, hips and back are all held straight upright and locked to prevent the leg and back muscles from assisting with the lifting effort. In addition to working the shoulder muscles, the exercise improves balance and works the muscles that stabilize the trunk and abdomen. The exercise is safer than a bench-press because the exerciser cannot end up trapped under the bar.Learn more about Muscle Toning
