Training with the SSYoke bar always ruins me.  My first day back to training squats and of course it's the type of squats that I suck at the most. Because of the positioning of the bar, it pretty much ruins my upper/mid back and makes me fight to stay upright on harder reps. Then after squats I had to do good mornings with it too.
It hurt to move, or even breathe the day after.
