Scapular push-ups, scapular rows, handstand shrugs, dip shrugs, RTO ring support holds, and passive and active hangs are all excellent tools for building scapular strength, but they can get a little boring once you’ve master them.
I still do them, but a good place for them is in the warm-up as activation drills.
If you're new to SASS and you're still getting ready to train front levers, planche and handstands, what can you do to build SASS?
