rfitz_crossfit: Some close up Chest-to-bar action. I challenged my teammates to a GRID style speed test; 20 1-arm KB Overhead squats (70/53#) and 20 chest to bar pull-ups. My time was :51 sec. Can you beat it?? Post a video and tag me with you time! #crossfit #grid #gridinvitational #texasbloodhounds #gridspeed #gymnasty #compete #pryourlife #247365 #panthergainz #cfpc #fitaid #sfh #forHim
