Okay, Nick, you inspired me. I was going to take a rest day and carb up, but I felt pretty good and wasn't really hungry, so I'm powering through. I dusted off the old Turbofire DVDs, since it's a good workout and I needed a break after 3 days of running. There's not as much twisting as I thought in the upper body. Or at least not the way I do it, where I'm mostly facing forward and have my eyes glued on the screen to keep track of the moves. Of course, you'll have to see if it will work for you.
It does take a bit of rhythm, but I keep it light on the feet. If I get confused, I'll keep moving, hopping around a bit, like when boxers move around a ring. Many of the moves are pretty similar across the videos. The more complex moves took me about three workouts to get it right, occasionally hitting pause and practicing for a minute until I got coordinated.
There's a bit of jumping, but the Asian girl on stage always demonstrates the low impact version. Even with the normal version, it feels far easier on my joints than running. Although, my shoulders are a bit sore from all the punching moves.
I don't know what your wife does for exercise, but you might enjoy it together. The first time, I lost the final 20lbs doing only the videos. The second time, was with running only.
Here's a
YouTube clip.
I got a Concept II D rower and have been very happy with it.
I really, really like the concept of rowing, since it works the whole body. Though, my body just gets bored with the repetitive motion. Same thing with stationary bikes. Though, I find running and stairmaster somewhat meditative. There's something for everyone!
