I don't really consider the dynamic back squats as WSBB does them to be a speed lift (if I'm misunderstanding what we're talking about here let me know…I'm assuming 70% + bands as west side uses). The actual loads tend to be significantly greater than they mention. The body can't tell whether the resistance is rubber or iron and as a result despite them only saying a 70% load the loads typically range from 80-100% of max at any given point of the lift.
when i used such lifts they were always with green bands + 30-50% bar weight bc anything more bar speed suffer. so would you ever use such a setup and when, mon: heavy bsq, wed: jump squats, fri: dym box speed squats. also i thought wsbb stayed in the 50-60 range
