Coach Glassman says it best:

Got a question from a member today...

Yesterday we had another heavy day (Snatch + OHS) and I found myself pretty tired 3 hours post-WOD, but faced with an opportunity to join Merin's Fitness Flow class at 5 pm. I jumped in, only to hear "today's flow is going to feature some 2 minute plank holds!"  Yikes. That's going to suck.

Let's talk about an interesting occurrance that happens within our community at the gym and in the physical activity world in general. "Intimidation" is the one word description, but really it's a phenomenon that cuts deeper into the psyche of our relationship with exercise.

Today's workout brings us to a great teachable moment. CrossFit is only CrossFit when done with intensity (unless you are a beginner and still learning mechanics and consistency.) But intensity has variety, just like our movement combinations have variety. We have sprints, marathons and middle-distance efforts which require very different strategies going into the workout.

It's dumping snow outside and we ARE open.  Come on in and play with us. 

...or at least getting smarter:

"At the end of the study, the kettlebell exercisers reported less pain as well as improved strength in the trunk and core muscles, compared with the control group. Over all, working out with kettlebells reduced lower back pain by 57 percent and cut neck and shoulder pain by 46 percent."

"Kettlebell training is also surprisingly aerobic. A study by the American Council on Exercise found that a 20-minute kettlebell workout burns about 21 calories a minute, the equivalent of running at a six-minute-mile pace."
