Hooverball Party!
Classes are off! Hooverball is on! (and maybe some CrossFit Dodgeball too)

This Saturday, we are scrapping our regularly scheduled program for a little fun and games, CrossFit style. Come throw heavy balls around, eat paleo snacks and drink (non-paleo) beer. NFT.

The Details:
When: Saturday 11-1pm
Where: Upstairs at the Lyceum
Who: SBK peeps, family and friends

This is a BYOpaleo! If you'd like to bring snacks and/or beverages, email Margie at

Please note: All classes, including the teaser, are cancelled. There will be an hour of open gym after 1pm if you need to get more action. Or you can just retire to Sheep Station for more beer and burgers. (Without the bun of course.)
