When loads were increased to 85% 1RM, subjects squatted approximately 5–10° less during the above parallel and parallel squats. This may be done to decrease the difficulty of the exercise as loads become heavier. With below parallel squats where the thighs come into contact with the calves, there is a natural stopping point as a lower depth cannot be achieved. This eliminates the possibility of unintentionally going below the intended depth where there is an increased probability of a failed repetition.
