Well folks, 16.5 is........ 14.5. The brutal, task priority (you have to do all the work, no being saved by the timer in an AMRAP) finisher from the 2014 season, we get Thrusters (thought we'd just get to skip those, huh?) and burpees.
For those of you who enjoy math, its 84 reps. Of each.
Thrusters at 95/65 RX, 65/45 Scaled.
