  • The left foot has now come forward so it is in line with the right foot and the body is going more in the direction of the intended target

Shoulder Girdle
  • The right shoulder is adducting with the middle and lower trapezius and rhomboid contracting concentrically
  • The right shoulder is also elevating and rotating upward with the upper and middle trapezius, rhomboid, serratus anterior, and levator scapula contracting eccentrically
  • Left shoulder is abducting with the pectoralis minor and serratus anterior contracting eccentrically
Shoulder Joint
  • The right shoulder joint is abducting with the supraspinatus deltoid, and upper pectoralis major contracting concentrically
  • The right shoulder joint is also externally rotating with the infraspinatus and teres minor contracting concentrically
  • The left shoulder joint is horizontally adducting with the pectoralis major, anterior deltoid, and coracobrachialis contracting concentrically  
  • The left shoulder joint is also internally rotating with the latissimus dorsi, teres major, pectoralis major, and subscapularis contracting concentrically 
Elbow Joint
  • The left elbow joint is flexing with the biceps brachii, brachialis, and brachioradialis contracting concentrically 
  • The right elbow joint is flexing with the biceps brachii, brachialis, and brachoradialis contracting concentrically
Radioulnar Joint
  • The left radioulnar joint is pronating with the pronator teres and pronator quadratus contracting concentrically
  • The right radioulnar joint is slightly supinating with the biceps brachii and supinator contracting concentrically  
Wrist and Hand Joint Movements
  • The right hand has flexion of the fingers and thumb with the flexor digitorum superficialis, flexor digitorum profundus, and flexor pollicis longus contracting concentrically
  • The right wrist is in neutral position contracting isometrically
  • The left hand has flexion of the fingers and thumb with the flexor digitorum superficialis, flexor digitorum profundus, and flexor pollicis longus contracting concentrically
  • The left wrist has slightly flexed back to neutral position with the flexor carpi radialis, palmaris longus, flexor carpi ulnaris, flexor digitorum superficialis, flexor digitorum profundus, and flexor pollicis longus contracting concentrically
