You could get away with doing chins and squat on the same day, but doing all three may be too taxing on the body.
personally i would do bench on day 1 and do your assistance work for bench then on depending on how you feel do the chins and squats on the following day or give it another day of rest.
make sure you do a good warm up, also make sure to ramp up your weights for instance i tried my max on standing military press a couple days ago. I was shooting for a 170 lift so i did 135x5, then 145x2, 155x1, 165x1, 170x1 this way ensures your body is ready for the max lift, but at the same time isnt too taxed from doing 5x5 each set.
Another method you can do is take a basic estimate of what your 1rm would be, lets say you can do 5 reps of 185 for bench that would roughly be a 215 max you could take 90% of that number ~195 and do a set of that and see how many reps you can get which if your previous est is on you should get 3 reps or more. This method isnt perfect, but you can get a general idea or what your lifts are at.
I have tried that program, but does he have a formula that you figure out your 1 rm? in general keep to one formula you can plug those numbers into 3 different calcautations and get 3 different numbers. [/quote]
Thanks for the response. Yeah I’ll think I’ll go ahead and do bench + assistance work tomorrow, then chins and squats probably on Wednesday. So you’ve tried Built Like a Badass already? I don’t think he has a 1RM calculator, but if I end up using one, I’ll probably use the one at exrx.
