as previously mentioned in another thread, I started Insanity this week. In fact, as I type this covered in sweat and trembling, I just finished the last workout for this week. I've done a couple of rounds of P90X and they were great for putting on muscle (and I did lose a bit of weight the first time), but I needed something with more cardio to keep burning the fat off. I'm telling you, this is the hardest workout I've ever done. Seriously. And I'm a strong cardio guy even though you probably couldn't tell by looking at me (I could go out and run 10-15 miles on a whim at an 8-8:30/mile pace and I regularly run the 1.5mi test for my team in about 10:30ish). If you're in pretty decent shape AND looking to shred every last ounce of fat on your body, DO THIS WORKOUT! I'll periodically post some updates and (if they're flattering enough) I may post some after pics.
