Man!! Squatting without the mirrors is freaking awesome..feels so much more natural. 85% felt like a warmup. Am a deep squatter but definitely noticed more depth and most importantly more explosiveness. Never believed that training in front of the mirror would impede someone's squat performance to such a degree. Same for the deads. Gonna start doing this with the overhead presses as well.
I aspire to compete in powerlifting so I better get used to squatting without mirrors. I guess someone competing in bodybuilding would beg to differ.
