Re: Hybrid programs
Gant, I just love reading about your "experiments"---first, your Tabata data, and now this.
You write that this experiment "ended." Do you have another direction in mind?
If nothing else, it shows that gains are made when we vary the demands we put on our bodies. Certainly, that's built into the daily structure of the Crossfit program. I haven't followed the sequence of WODs closely enough over the time I've been around, so I haven't perceived larger cycles imposed upon (emerging from) the WOD sequence.
One thing I do know is that really elite athletes have seasons in which they train to a peak, so there is seasonal periodicity built into their programming.
There are two ways to "go at" Crossfit: as a fitness program in progress is a side benefit, and as a sport in which performance uber alles.
For those folks whose sport is Crossfit, more attention to seasonal periodicity---larger patterns of training variability----might be useful. I'd be interested if you took on an endurance running or cycling program next!
