First off I’ve been working out for about 6 years now but recently I’ve began to be more dedicated to getting healthy. I love to work legs but I have a moderate case of “knock knee” and have short thighs. So it makes proper squatting technique difficult. I have a hard time getting my butt low enough on squats and have been recently using a bench to place Behind me to let me know when I’ve gotten low enough. Is this cheating or bad for me? Anybody else have this problem? Thanks for your time.
