How about SLDL's as a substitute? I started doing the dynamic stretching shown on Squat RX #4. I ordered a 3"x36" foam roller from a site posted in a thread recently. W/shipping 15$ cheaper than the local sporting goods store,thanks Eric. Heading to the gym. Squat, bench. deadlift today. I'll try SLDL's in place of squats and see if the break helps. On this workout I do dips and the other I do assisted pull-ups are these good assistance moves for these workouts?
