Get stronger more toned arms with New Slendertone Arms Male Accessory (requires a rechargeable & interchangeable controller). The product activates biceps (biceps brachii) and triceps (triceps brachii), replicating arm toning exercises for a full workout.

The New Slendertone Arms Male Accessory uses advanced clinically proven Electronic Muscle Stimulation (EMS) Toning Technology to target the biceps and triceps, helping you to achieve more toned, stronger arms.

All Slendertone products use EMS toning technology, which works by sending signals to your nerves to contract and relax your muscles, similar to regular toning exercise. This EMS technology has been used for over 50 years in sports and medical environments to strengthen and rehabilitate muscles.

Use 5 times a week for 6 weeks for a guaranteed improvement in upper arm definition. This New Arm Accessory is designed for men with the orange detail and packaging.

Independent clinical study* has proven after 6 weeks:

• 89% of subjects reported their arms were more defined
• 72% reported that their arm muscles were firmer

* Trial conducted by Platinum Research, Galway, Ireland, 2007

The Science:

The biceps brachii has two separate tendon origins (known as the long and short heads) on the front of the scapula (shoulder blade). The biceps are a powerful flexor of the shoulder and elbow and also supinate the forearm (turns the palm to face upwards). 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. This 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, and this is why the Slendertone System Arms Male Accessory targets both the biceps and triceps when used. 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 receive regular exercise at a sufficient intensity will also rapidly lose their tone with the muscle fibres being replaced eventually with fatty tissue.
