Layne, I'm 53 and obviously not as young as I used to be. lol I do 2 strength training days and 3 cardio days (because cardio helps me burn off excess energy and tension). My mind still needed 3 cardio days, but my body wasn't handling it well. In addition, I'm underweight, so the cardio seemed to be undermining my strength training efforts as I aged. Anyways, I used to do the much more challenging cardio. Now, I've found that what works well for me is to do 1 hard cardio (anaerobic), and two steady state cardios a week. You're doing two cardio days a week, and I was wondering what level they are at. If they are anaerobic, you could change one out to steady state. I generally still work out to Cathe, but if I'm not feeling well or my body is telling me to take it easy, I'll work out with Jessica Smith. She has some great walking videos, but I'm thinking that with your foot issues... the workouts might be gentler on your body, but it's still a lot of strain on your feet. I would like to mention, though, that a walking video is not what it sounds like. So, if your foot gets better and you want to try it, it can involve bands, weights, or no equipment. The walking videos will have moves with your arms above your head, a variety of different steps (ex. grapevine, V step, etc.), so I don't find them boring. For you, with your current conditions, however, that you try Jessica Smith's "Feel Good Fusion" DVD. It has two workouts on it. It's not a walking video. It's more flowing? They are workouts that can be done barefoot, so no impact. They are steady-state cardio, with one of them involving small weights to ad a strength factor. The other uses no equipment. They are kind of barre/pilates/yoga inspired movements that are different from anything I've ever done before. It is not unusual for me to do 2 Cathe cardios in a week and make my third cardio a Jessica workout. While Jessica's workouts aren't as challenging (physically) as Cathe's, they do challenge you to think (movements are creative) and balance (often optional or can be modified) while providing movements that have helped my mobility and range of motion. I also have found over the years that I can't take "rest" days. So, my other two days of the week are active recovery days that I use for yoga, Tai Chi, Essentrics/Classical Stretch, mobility/range of motion, stretching, etc. - just whatever my body needs that week. I call them my "healing" days. I have to keep moving or my body gets stiff and my mind gets restless, but my movement those two days is focused on recovery. Anyways, you might want to check out Jessica's "Feel Good Fusion" for at least one of your cardio days. If your foot heals, you could try some of her other workouts on that day for variety. I have found that a Cathe/Jessica combo works well for me as I'm getting older. I still do more Cathe, though, because when I'm done with one of her workouts, there's a feeling of pride that I survived it. lol It's an ego trip for me. lol
