Sorry for the major bump, but I've used this too and had more info.
It's basically crossfit, but not as hard on your body. It's usually four 30 second exercises back to back followed by a 1 minute break. Most workouts are an hour long including the breaks, warmup, and cooldown. Warmup and cooldown are about 20 minutes combined. The only one that's over that is yoga, which is 90 minutes. It's marketed as turning people into chiseled bodies and it can do that by repeating the 90 day thing, but it really seems to be meant more as a fitness bootcamp to get you in enough shape to do other things.
