I agree with those comments. I think that CrossFit is a great way to approach fitness, but not endurance sports or triathlon. Spending 20min a day tossing around kettleballs will not make you run or swim faster. --------------------------------------------------------------------------------------------------------------------- Reminds me of the hype around "high intensity training". Does anyone remember the late Artur Jones of Nautilus/Medex fame. He was a strong proponent of weight training HIS way. 20 minutes/day every other day. Anything else was counter productive because you had to use your down time for full recovery in order to prepare yourself for thre next high intensity workout. He claimed that you not only developed strength, but also endurance from training with weights. He was anti-running and he said running would only cause injuries. There are still a lot of high intensity training people out there and they have various different names like "super slow" http://franchise.superslowzone.com/what-is-superslow-zone There is some benefit to their training, but they are closed-minded to any other form of training.
