Best Newbie Box. End of Story.
When I decided to get into Crossfit I tried out a few "boxes." At most of the other gyms they'll put you in 3x 1hr fundamentals classes then throw you in with all the other folks...ummm, what? I've never done snatch or a clean or a wall ball in my life. Not here, at CFSE there is a maniacal focus on technique that makes it a really great, safe environment for folks new to Crossfit. The coaches are patient and super encouraging. They're great about scaling the workouts according to ability but they'll certainly never make it easy.
It will absolutely kick your ass but you'll happily pay to come back for more!
