At the beginning of each cycle 5lbs (for upper body) is added to your 1RM. Is this the 1RM you started with or any new 1RM you achieve during the cycle you’ve just completed?
For example, if at the start of cycle 1 I could bench 120lbs for 6 reps, my calculated 1RM would be 144lbs. 90% of this is 130lbs.
In week 3 my 1+ set would be 95% of 130 which is 124lbs. If I managed 6 reps then my calculated 1RM is now 149lbs.
So at the start of cycle 2 do I add 5lbs to the initial 1RM of 144 or to the new 1RM of 149?
