I've used Fitness+ since release, and if you're not getting the rigorous workout you desire, you're simply not working hard enough. Because there's nothing holding me back from drilling myself straight into the ground during rowing intervals. OTOH, I can sit there and just cruise if I like, with no one the wiser. Strength workouts: grab bigger dumbbells. Etc, etc. The only workouts I can think of where this strategy might not work are yoga and "mindful cool down". And maybe the weightless core workouts, dunno.
