Well, I've only done about 10 minutes of turbofire before realizing it's not for me and I've done 4 consecutive rounds of Insanity, so obviously, I'm a little biased...but my opinion is the main difference is Turbofire is very dancy (which is what did me in; I can't dance!), whereas the moves in Insanity are straightforward - you won't feel like you're on a dance floor when doing them. The principles in both programs are similar (using HIIT training). I think the best exercise is the one you'll keep with, so if you enjoy dancing and have a sense of rhythm, turbofire might be perfect. If not, and you just want to get a good, intense, no frills workout with a lean, mean crazy person screaming at you to "dig deeper," try Insanity. I hope that helps!

Personally, not an Insanity fan. I DO the workout and it's a GREAT workout but for me, it lacks the "fun" factor. Does it work? ABSOLUTELY. I've actually completed 3 rounds of it. However, I find that I do best with it mixed into a hybrid so if really depends on what you like about Turbo Fire. Both are HIIT workouts - high intensity interval training - but with a few differences.

Insanity is a very straight forward drill type workout. Like most Boot Camps (which I taught). There are several of the moves found in P90X plyo plus a few new ones. Jumping Jacks, pushups, tuck jumps, burpees, suicide drills...a LOT of plyo work done in intervals with very short breaks.

Turbo Fire is very similar to Turbo Kick workouts done in gyms (which I also taught). It's kickboxing on crack The HIITs are just what Chalene calls "turbos" in her regular workouts only done back to back. These are the highest intensity part of each workout. When you do them with very short breaks, you get the HIIT training. Where Insanity gives you 30 sec. breaks after a 3 min push (except in Pure Cardio), Turbo Fire gives you 30-60 sec breaks after every min. You are able to catch your breath more.

Insanity has a longer PUSH for each interval and shorter breaks. One workout has a 20 min push with NO break. I personally believe that Insanity gives you a better HIIT workout because it offers more variety. But like I said, there is no FUN in Insanity. You should be dying from the warmup alone
