I started Turbo Fire in May with the 5 day Inferno. I have continued to do some sort of Turbo exercise nearly daily ever since that time.
I now run 4 days a week and do a high intensity turbo workout after my 40 minute run outside. I try to run every other day. On my off running days, I do a turbo fire workout to make it at least a hour long, so Fire 55, 60, 45 plus a hiit, etc. I am still not bored, and I am not tired (Chalene always says, "You are not tired!).
I love the longer workouts, the HIIT workouts and the ab workout. I have to be careful with the ab workout as I have pulled my neck bad once and had a minor strain another time. So, I try to only do the ab workout 1-2 times a week.
As far as nutrition, I continue to watch what I eat, but I do eat what I want in smaller quantities. I learned things from the 5 day inferno nutrition plan that I use even now, but I could not survive without chocolate or ice cream or on so few of calories.
So, after a few months, I do see a major difference in my body. My abs and arms are tones. I see a big difference in my upper body as I was pretty weak before. I like the high impact workouts. Having done Insanity, I find Turbo Fire to be higher impact. I wear a pediameter daily, and sometimes I can get up to 7000 steps in one Turbo Tire workout. That is almost as many steps as I get running (and I run about 4 1/2 miles!).
As far as injuries, I have had a couple. I strained my neck twice, as I mentioned. Now, I have a knee injury. Since I run, too, I am not certain the knee injury is from the Turbo Fire or from running, but I happened to notice it during Turbo Fire. I now walk/run with a limp, and I am really favoring it during my Turbo Fire workouts. With that said, it is nothing like the broken foot I got while doing Insanity.
Weight: Maintained (which was the goal).
