When this set first came out, it received so many positive reviews here that I was constantly tempted to buy it. But then I'd watch clips and think that Leandro was a total goofball and that he'd drive me nuts. Eventually, after about a year when a lot of the hoopla died down, I did buy the set and fell in love.
And not just with High & Tight and Bum Bum, which seem to be the most popular dvds from the set, but also Cardio Axe, Sculpt, and Tummy Tuck. The latter two IMO are awesome sculpting routines! To me, they are super effective and a lot of fun. I don't mind the scene switches; it adds a little flavor to the workout. Leandro is adorable, has a great sense of humor, and is very supportive. (He's also extremely easy on the eyes, if that matters to you.)
My legs were already in pretty decent shape and, truthfully, I didn't notice a major improvement there. But I definitely noticed my waist and abs looking leaner and tighter, and my upper body looked more defined.
I loved the basic set so much I also bought the deluxe dvds. Of that set, I think Rio Extreme is a fantastic cardio/sculpt workout. I got a lot of use from that one. Abs Rapido is a good 11 minute core workout, which offers different exercises from Tummy Tuck, but is not nearly as tough or as fun; the music is also pretty bad. In some parts, it sounded like '70s porn! I previewed Upper Cuts but never actually did it. I don't remember why I was never able to fit it in. It's one of the shorter workouts at 12 minutes.
Also wanted to say that when I watched the clips I thought his background exercisers were probably just pretty young things who were chosen for their looks, but those women are STRONG and always demonstrate good form.
