Warmup however you like, just make sure you cover the overhead position and the squat.
40 sec plank, R plank, L plank. Rest 15 sec. L plank, R plank, 40 sec plank
3 rounds, quickly but not for time:
MAx effort FS 155#
1:00 jerks 2xkb
30 sec overhead hold
If there's 4 of us, we'll do I go/you go. One works while the other rests & keeps time.
