A back squat cue is: HIPS BACK. Note the difference ー for the front squat, the cue is HIPS DOWN. The back squat has better leverage, so the hips can go farther back, optimally engaging the glutes & hams. This helps move the load from a solid foot position, rather than from the toes. Do NOT squat on your toes. Tendons are weak, bones are strong. Hips-back brings more of the posterior chain into the movement, so more weight can be lifted than with the (poor-leverage) front squat.
WHITE-ORANGE should be focusing on technique and consistency across sets. Only add weight if reps remain crisp. BLUE-PURPLE+ can push the weight, but not to a max. Build to a smooth Single (or 3 reps) with solid technique. No sketchy reps just to post a bigger number.
