The Science

The triceps brachii has three separate tendon origins (known as the long, lateral and medial heads) on the bony architecture of the scapular (shoulder blade) and the humerus . The triceps primary role is that of a powerful extensor (straightener) of the elbow joint, but it can also fixate the forearm so as to allow the hand to carry out skilled and intricate tasks. Because of the long heads's origin on the scapula the triceps also influence shoulder extension. Many gym goers tend to neglect the triceps muscle in their training schedule, preferring instead to concentrate on developing the more aesthetically pleasing biceps muscle, and this is why Slendertone Arms Female Accessory targets just the triceps, the area most women find harder to tone.

Focusing on the biceps muscle is a mistake as a contracting muscle is reliant on the opposing muscle working to counteract its pull so that a smooth co-ordinated action around the targeted joint can occur. This effect is known as agonist and antagonist contraction and, if disturbed, results in a muscle imbalance leading to movement dysfunction and eventually pain. Muscles which do not recieve regular exercise at a sufficient intensity will also rapidly lose their tone with the muscle fibers being replaced eventually with fatty tissue.
