>>4801467As many as you can, I suppose. Track how many you can do and try to increase the reps each time.
If you're doing a lot of squat volume, you need to make sure your form is good and doesn't break down after a while.
Only do as many reps as you can with good form.
Ideally an ass to grass squat with a 1 second pause at the bottom would be perfect since it takes more effort and engages more muscles, so you don't have to do as many reps.
