Started Madcow 5x5 Friday using a 1 rep max of 440lbs. I was able to do all 4 sets of the deadlift. I'm only using the Deadlift once a week part of Madcow so I can hopefully reach 500lbs. Well today I felt good and tried a 1 rep max & got 450lbs. Should I change my Madcow 1 rep max to 450lbs and start with this number for Week 2 Friday (4/26)?
Also do you think I probably could have gotten more than 450lbs? Deadlift Advice?
Also what do you think of the breathing technique I used? First time trying it.
