A. Back squat – 5×2@84%.
B. Alternating with a partner:
20 rounds (10 each) of 30 seconds row/bike for calories. If you’re working solo, keep a 30 second rest interval. These should be done at a challenging pace, but don’t blow up on the first few rounds either.
C. 3 max effort sets of tuck holds or rocks, or straddle holds or rocks.
