My working sets for the big 4 lifts are as follows (Estimated 1RM in parenthesis):
Deadlift: 375lbs x5 (1RM 435lbs)
Press: 120lbs x5 (1RM 135lbs)
Squat: 245lbs x5 (1RM 285lbs)
Bench Press: 195lbs x5 (1RM 225lbs)
When using an online calculator for the 5/3/1 BBB program, should I be using my estimated 1RM (I’ve never maxed out before) or use my 5RM?
