- Right arm should be above left arm.
- elbow of right arm should be bent (flexed) at about 45 degrees and wrist should be slightly abducted.
- elbow of left arm should be slightly bent (flexed) and wrist should be adducted slightly.
- right shoulder should be slightly flexed.
- left shoulder should be relaxed.
PULL PHASE (PART ONE)
- Pull wheel down by using your right arm.
- Right shoulder should extend slightly and right elbow should flex more.
- Let right arm do the work, left arm should just be following through.

- suscapularis, concentrically, in sagittal plane to pull down wheel by slightly extending shoulders.
- latissimus dorsi, concentrically, in sagittal plane to pull down wheel by slightly extending shoulders.
- teres major, concentrically, in sagittal plane to pull down wheel by slightly extending shoulders.
- teres minor, concentrically,in sagittal plane to pull down wheel by slightly extending shoulders.
- Elbow/ Radioulnar Joints:
- Biceps brachii long head, concentrically, in sagittal plane to flex elbow.
- Biceps brachii short head, concentrically, in sagittal plane to flex elbow.
- Brachialis, concentrically, in sagittal plane to flex elbow.
- Brachioradialis, concentrically, in sagittal plane to flex elbow.
- Wrist/ Hand Joints:
- Flexor carpi radialis, concentrically, in frontal plane to slightly abduct wrist.
- Extensor carpi radialis brevis, concentrically, in frontal plane to slightly abduct wrist.
- Extensor carpi radialis longus, concentrically, in frontal plane to slightly abduct wrist.
- Extensor pollicis longus, concentrically, in frontal plane to slightly abduct wrist.
- Extensor pollicis brevis, concentrically, in frontal plane to slightly abduct wrist.
- Abductor pollicis longus, concentrically, in frontal plane to slightly abduct wrist.
- Flexor digitorum superficialis, concentrically, to flex fingers to grab the wheel.
- Flexor digitorum profundus, concentrically, to flex fingers to grab the wheel.
- Extensor digitorum for fingers to let go of wheel.
- Extensor indicis for fingers to let go of wheel.
- Extensor digiti minimi for fingers to let go of wheel.
PULL PHASE (PART TWO)
- alternate arms when pulling down the wheel.
RELEASE PHASE (PART ONE)
- slowly release the wheel in the opposite direction.
- shoulders should flex slightly and elbow should extend slightly.
- Glenohumeral Joint:
- Pectoralis major upper fibers, eccentrically, in sagittal plane to control flexion of shoulder.
- Deltoid anterior fibers, eccentrically, in sagittal plane to control flexion of shoulder.
- Elbow/ Radioulnar Joints:
- Triceps brachii long head, eccentrically, in sagittal plane to control extension of elbow.
- Triceps brachii lateral head, eccentrically, in sagittal plane to control extension of elbow.
- Triceps brachii medial head, eccentrically, in sagittal plane to control extension of elbow.
- Anconeus, eccentrically, in sagittal plane to control extension of elbow.
- Wrist/ Hand Joints:
- Flexor carpi ulnaris, eccentrically, in frontal plane to slightly adduct wrist.
- Extensor carpi ulnaris, eccentrically, in frontal plane to slightly adduct wrist.
- Flexor digitorum superficialis, concentrically, to flex fingers to grab the wheel.

- Extensor digitorum for fingers to let go of wheel.
- Extensor indicis for fingers to let go of wheel.
- Extensor digiti minimi for fingers to let go of wheel.
RELEASE PHASE (PART TWO)
- alternate arms while releasing the wheel in the opposite direction.
Drill/ Home Exercise:
The following is the arm bike that will help get the shoulders moving and alternating.
