L3D1: 20 rounds
I think I found my level. The increase in difficulty by doubling up the pullups was really really marked
I managed 8 rounds of straight pullups, did a 3x sub round, then managed to get to round 12 without another sub, rounds 13-15 included at least one pullup with a set of subs. Rounds 16+ were all subs. My arms and shoulders felt like jello afterwards.
On the bright side I am already noticing strength gains, and people are beginning to comment. Not just on how I look, I must be walking straighter or something because everyone thinks I'm in a better mood....although it does beg the question if I have a reputation for being a not so good mood
