I've been doing home aerobics videos/dvd's for years and having tried nearly all of them out there, this is the first one I tried (passed from mother to daughter!) and I can safely say this is probably the best one I have ever used! It is has the most thorough warm up and cool down, its safe (I've never pulled anything doing this - unlike most other dvd's), covers all areas (aerobic and conditioning/toning) and most importantly IT WORKS!! Whenever I've been a bit lax, this snaps me back into shape, with obvious results of 2-3 times a week after just a fortnight.
I cannot recommend this highly enough. If you can get past the nightmare 80's lycra and music, its one of the best, most effective, well thought out and complete exercise routines I've ever done. (Its of a very similar fitness level to Davina/Charlie Brooks)
