TorsoSpin is a new version of what physical therapists call an Upper Body Ergometer or “arm bike.”

Rugged and versatile, TorsoSpin is designed for general strengthening and conditioning by people of all fitness levels, with the effectiveness and safety that physical therapists have long appreciated in ergometers.

Upper body ergometers are low impact and highly adaptable:

Adjustable Resistance: A user can begin the resistance at a very low level and gradually increase it as strength increases.

Controlled Movement: The fixed-path motion is safer than using free weights.

Provided to fitness and health clubs, TorsoSpin is designed for use in a class led by an instructor.

Physical therapists use Upper Body Ergometers to:

Increase Strength: It targets the muscles of the shoulders, arms (biceps and triceps), chest, and upper back.

Improve Range of Motion: The smooth, repetitive, and bi-directional (forward and backward) motion is perfect for gently restoring mobility in the shoulder, elbow, and wrist joints, especially after surgery (like a rotator cuff repair) or injury.

Build Endurance: It helps patients rebuild muscular endurance in their arms and shoulders, which is essential for daily activities like lifting, pushing, and pulling.

What muscles are worked during a TorsoSpin workout?

Arm muscles

Biceps: These muscles on the front of your upper arm contract as you pull the handles toward your body, particularly when using the “curl” grip.

Triceps: The muscles on the back of your upper arm extend the elbow joint as you push the handles away, and as you row downward

Forearms and wrists: The smaller muscles in your forearms and wrists are activated to maintain a firm grip on the handles. 

Shoulder and chest muscles

Deltoids : All three heads of the deltoids—front, side, and rear—are engaged to stabilize and move the arms, with a particular focus on the front deltoids during the pushing phase and the back deltoids during the pulls.

Pectorals : Your chest muscles assist in the pushing motion, particularly downward, while helping to stabilize your upper torso. 

Back and core muscles

Upper back : Trapezius and rhomboids work dynamically during each push and pull 

Lower back: Flexes and twists gently as effort alternates between right and left handles

Core : Abdominals and obliques  contract and release with each “pump” as you transmit power from your torso to your arms, and work isometrically to stabilize your body on the machine

By changing your grip (palms down or up), your seating position (forward or back), your posture (seated, standing, kneeling, or on your back), and the height of the seat,  you change the angle of effort and thus vary the muscles, ligaments and joints engaged and conditioned.
