• As the right arm starts to coming foward, the legs begin to push off the ground and your body begins to rotate to the left through the swing
• The belly button eventually ends up out towards intended target

Shoulder Girdle

• The right shoulder girdle is in upward rotation with the serratus anterior, middle and lower trapezius muscles are contracting eccentrically 
• The right shoulder girdle is also in elevation with the middle and upper trapezius, rhomboid, and levator scapula contracting concentrically 
• The left shoulder girdle is in adduction with the middle and lower trapezius and rhomboid contracting concentrically

Shoulder Joint

• The right shoulder joint is abducting with the supraspinatus, deltoid, and upper pectoralis major contracting eccentrically
• Towards the end of the movement phase, the right shoulder joint goes into flexion with the anterior deltoid and upper pectoralis major contracting eccentrically
• The left shoulder joint externally rotating with the infraspinatus and teres minor contracting concentrically   

Elbow Joint

• The right elbow joint is extending with the triceps brachii and anconeus contracting eccentrically
• The left elbow joint is flexing with the biceps brachii, brachialis, and brachioradialis contracting concentrically

Radioulnar Joint

• The right radioulnar joint is pronating with the pronator teres and pronator quadratus contracting concentrically
• The left radioulnar joint is pronating with the pronator teres and pronator quadrus contracting concentrcially   

Wrist and Hand Joint Movements

• The right hand has flexion of the fingers and thumb with the flexor digitorum superificialis, flexor digitorum profundus, and flexor pollicis longus contracting concentrically
• The right wrist goes back to neutral position contracting concentrically
• The left hand has extension of the fingers and thumb with the extensor digitorum, extensor indicis, extensor digiti minimi, extensor pollicis longus, extensor pollicis brevis, and abductor pollicis longus contracting isometrically
• The left wrist is in neutral position contracting isometrically
