New to Catalyst, looking for exercise clarification
I'm a long time gym rat, crossfit toddler. I recently got my OHS down pretty solid, and am pretty confident in the snatch, so I'm going to do the WODs here for a bit to strengthen my identified weakness- the oly lifts.
I'm a little lost in some of the exercise RXs, for example-
A1. Pull-ups x 6; 21X0; add weight each set as needed to hit reps; 1 min rest
A2. GHB sit-ups x max consecutive; 2010; NO failed reps; 2 min rest
On the pullups, what does the 21x0 mean? And on the sit ups, 2010?
help me out, thanks in advance
