After a CFWU of 2x15
With a continuously running clock, and a 45# barbell, do 1 squat the 1st minute, 2 the 2nd and so on, until you can no longer do the required # during that number round.
Me: 20 rounds +14 singles
Sgt V: 12 rounds +7
Sgt K (used the smith machine, added 2x10# plates to make it seem as difficult, and later took it off): 14 rounds flat
After we ran a treadmill mile at own best paces and found that all of our legs were toasted.
