I hate stability balls. There was a guy in the gym this morning with a SB in the squat rack, a BB with about 3pps set on low pins, he was face down on the ball with his feet under the bar and the pu55y pad across the back of his knees, doing hypers with 5kg held to his chest.....
There is a hyper station that was free !!!
