I was kind of curious what The Firm Cardio videos had to offer. I bought this one as an afterthought, to go with the Cardio Inferno. This one has a lot of mild techniques, but gets the muscles warmed up pretty good. I don't sweat as much with this one as the Infirno.I'm quick to pick up on the techniques, but also have to slow down at times to get the right form down. These videos are more my pace than anything I've seen in a long time. I've been stuck on one Pilate's video for many years. This is just the switch up I needed for the season.
