I only just realized how useful these can actually be for helping to improve your regular squat poundage, not so much for training the high point of the lift but for simply feeling the heft of supra-maximal loads and getting used to having more weight on your shoulders.
You can do 1\4 to 1\8th squat lockouts with much more poundage than you could with a full rom 1rm.
I was kind of wondering though,
When is the best time to include them in a training session?
Should you mainly just do singles with extremely heavy weight ?
What kind of volume, sets and reps do you typically do with this exercise when included with regular squats ?
If you do these, do you typically do them before or after full rom squats ?
