Yes! While you will not see crunches at San Francisco CrossFit, we know that a weak trunk and poorly stabilized spine is the single most significant limiting factor in all human movement and sports. To this end, our programming specifically addresses trunk or “core” strength.
A) 4 rounds for quality:
10 weighted pushups-5 false grip ring pullups-20 second ring support hold
*Scale to 10 strict pushups unweighted or 10 strict pushups with hands on elevated box
*Scale ring pullups to banded strict pullups, or jumping pullups with a 3 second negative
B) 16 minute AMRAP:
Row 500m-15 burpees to a 6″ target-20 alternating db snatches (50/35lb)
