• hip flexion = iliopsoas
• hip extension = gluteus maximus
• hip abduction = gluteus medius and gluteus minimus
• hip adduction = adductor longus, adductor brevis, adductor magnus
• hip medial rotation = gluteus medius and gluteus minimus
• hip lateral rotation = gluteus maximus
• shoulder flexion = anterior deltoid
• shoulder extension = posterior deltoid
• shoulder abduction = medial deltoid
• shoulder adduction = latissimus dorsi
