I absolutely love Turbo Fire. It's really difficult, but I love the music and I love Chalene. It was and is the only work out that really gets me motivated. So for me it has been worth the money.
go for it! i bought it a couple of weeks ago and i was hooked the first time i tried it, however, i hurt my knee so i cant exercise for a couple of weeks. i think about turbo fire every day! definitely buy it, i think it'll definitely be worth it lol
