This is the first excercise DVD that I have actually stuck with for over a year now, its a bit different than the usual boring aerobics, as it incorporates Salsa, so for me it takes my mind off the excercise bit! it would be however a bit too easy for advanced fitness freaks. Its nice and gentle to start with, progressing to a 30 min salsacise session, which I think is achievable and the toning bits are really good also. I have weak kness, but I find this absolutely fine, and have no problems. My husband also does this several times week and also enjoys it!
