I've tried a few of these. I don't think they are as good as Cathe's. The workouts are intermediate to low advanced IMO. I've been doing 2 workouts back to back. For example yesterday I did CVX and then did Pilates X. Also there's not enough weighted leg work And seems to work more on upper body. There's one workout called The Challenger that alternates push-ups and pull-ups for 30min. It has a good variety though. Weights, cardio, core, balance are all worked on. It has 4 stretching/balance workouts including a Yoga and Pilates workout. My favorite one so far is CVX. You hold a weight (I used a 5lb dumbbell) and do jumping or balance moves sometimes on one leg. I like P90X3 (not love) and will keep for the variety. I'm starting STS next week (2nd time) and the P90X3 cardio and stretching/balance workouts will add in well with my rotation. HTH
Wanted to add that there is a total body workout The Warrior that is body weight only. Haven't tried it yet but sounds like it would make a good travel workout.
