Trak Fitness TrakHandle Sport (Single Handle) Black

Trak Fitness TrakHandle Sport (Single Handle) Black Key Features:

Range Of Motion and Rotational Movement: Multiple studies have shown that the greatest gains in muscle development are achieved with Full Range Of Motion (ROM) exercises. The only way to achieve full ROM for the muscles of the upper body is with rotational movements.  The TrakHandle Sport and other Trak Fitness products are the only exercise handles and cable attachments available that allow the rotational movements necessary for full ROM exercises.

• Biceps brachii: Biceps are commonly known as elbow flexors. But they are also the primary supinators (external rotation) of the forearm.  To work the biceps through their full range of motion, the exercise must start with the forearm pronated and incorporate external rotation (supination) of the forearm while flexing the elbow.
• Pectoralis Major: The Pectorals horizontally adduct the arm. But they are also internal rotators of the arm.  To work the pecs through their full range of motion the exercise must start with the arm externally rotated and be rotated internally during the movement.  The pectorals also flex and extend the arm depending on the starting position and exercises should be performed to work the pecs from all angles. Rotational movement is critical to achieve full ROM from any position.
• Latissimus Dorsi:  The lats extend the flexed arm but they are also internal rotators of the arm. So full ROM of the lats is achieved by extending and internally rotating the arm during the exercise.
• Deltoids: The delts abduct (or raise) the arm but they also assist in external and internal rotation.  Full range of motion can be achieved for the anterior (front) and posterior (rear) delts by incorporating rotation into the movement.
• Rotator Cuffs: Its all in the name.  Enough said.
