Today I did squats with the safety squat bar for the first time. Man, it kicked my butt! Last time I did ME squats with the straight bar, I did 425, but today with the safety squat bar I could barely do 315 ( but I skied yesterday and I'm slightly sore from that ). So my question to everybody here is, Do you squat considerably less with a safety squat bar, and if so how much less? Does this point to a specific weakness that I should be focusing on?
