Tips for scaling:
For beginners, warm up the overhead squat​ starting with PVC and gradually increasing the load to working weight. Use a load that will allow ~1​0 reps per round with excellent technique. As you fatigue, do not decrease the load, instead, decrease reps and/ or increase rest time prior starting each overhead squat set.

For intermediates, Warm-up the overhead squat ​starting with PVC and gradually increasing the load to working weight(3/4 of your body weight). The load for the overhead squats is reduced so the intermediate athlete can achieve at least 5 overhead squats per round. If unable to do this, consider modifying to 1/2 body weight or less.
