The two researchers contented with improving the muscular balance between the upper and lower limbs, as this suits the motor path of the players when playing the penalty corner either in (flick or shooting) skills, because the motor path starts from (the lower limb passing through the trunk to the upper limb), so the two skills are the most important and the most used in penalty corner. Since the penalty corner mainly depends on power and ability, the two researchers designed a weights program for penalty corner players in order to improve their muscular imbalance, and also to recognize the effect of improving the muscular balance on the skill level, body structure, strength and body weight center.
