Breaking the ice to kick start the week! Monday lunchtime ass to grass squat singles up 520, alone in the gym!!! No spotters, no back slap, no women, nobody to help me achieve these lifts. But still I prevail with explosive mindset and thought control. I'm happy with this squat progression up to date. These vids shows: 315, 385, 435, 485, 505 and 520.
