Hi Sophia! I really enjoyed Chalean Extreme but I didn't really lose any weight from the program. I think I could have seen better results if I had stuck to a clean diet (tosca, Jillian michaels, and even Chalene are great choices for eating clean), needed to lose more weight than 5-8lbs, and if I had added more cardio in. With that said, I think you would see great results if you watched calories and added some cardio on your off days (MWF extreme TT cardio and the weekend could be cardio, intervals or yoga). If you have the time I'd try at least the burn circuit. Its tough and only 30 or so minutes leaving time for core or cardio. The whole theory is muscle helps you burn fat, but the burn circuit also made me sweat like a cardio
I hope all of that helped! Let me know what you decide! I've heard good things about the burn circuit more than anything else.
