Read a paper about people often estimating wrongly what feels like a heavy weight - i.e an erroneously low percentage of their 1 rep max.
Keen to avoid this, and having not tested it for a while, i thought i'd try my i rep maxs.
However, once i have them, what percentages should i use for WBB1 routine = 80%?
Obviously as i've been using the programme recently this is partly just as a check.
P.s - Ive lost the ref, but will hunt if anyone is interested
