I've done at least 4 rotations of the original STS and I remember doing an active recovery week between each phase. I remember Cathe mentioning things like walking, gentle yoga, recreational tennis, etc. Because I still had my elliptical at the time (wish I'd never sold it!), I would do very slow and easy elliptical workouts. When STS 2.0 first came out, one of the things I remembered thinking was about active recovery weeks, but I guess that wasn't included because there's so much recovery already built into the program. But, I'm a huge proponent of listening to our bodies and if we need a recovery day(s) or week, do it! I workout 6 days week and Sunday is a total off day, with the exception of walking my dog twice a day. Each walk is probably 15-20 minutes depending on if I stop and talk to neighbors.
I'm on week #2 of STS 2.0, I decided to stop the tank top rotation because I was just dying to jump into all these new workouts. I'm loving it. These total body workouts are serious weight training. And, someone said they were wiped out after Giant Sets. I can't agree more. That one is tough. I did cardio this morning, but it was a 40 minute Turbo Jam workout. I still love Turbo Jam and Turbo Fire for cardio. Turbo Jam is more dancy and fun where Turbo Fire is more intense cardio. I'm also planning to do a Hip Hop Abs 30 minute cardio this week. I love cardio, I have to include some in my rotation. But I'm following Cathe's advice of not doing anything more than 30-40 minutes long. These total body workouts have a cardio factor all their own.
As far as recovery is concerned, I'm making a more conscious effort to spend more time stretching, foam rolling or if I have extra time, doing one of Cathe's stretch DVDs. I love the no equipment one from Total Body Stretching. I also have Stretch Max, Yoga Max and Yoga Relax that I can throw in on a dedicated recovery day. I was introduced to the foam roller in 2012 when I went to Airrosti physical therapy for a neck/shoulder injury. They showed me how to foam roll for my specific area, but they also gave me a handout, which I can't find for the life of me, that showed total body foam rolling exercises. I pretty much have all of it memorized and try to foam roll after every workout.
