Adrian what are your other max lifts?
I'm not sure haven't maxed in a while, it's just the last two weeks I've felt stronger than normal on chest days, so I decided to see what I could get. I lift as heavy as I can legs days, try and stay heavy on squats, however I'm 6'3 and my form isn't the best, so I tend to have lower back issues. But I do what I can.
