Autumn:
just read everyone else's posts.
People often get anxious when they scale down from high impact to low. One anxiety stems from the fear that we won't get as good a workout (yes, we can, many of us here are living proof) and will stop losing weight or start putting it on (I've been doing mostly low impact for the last 3 years, and am lighter now that I was 5 years ago, staying around the 124-126 pound mark versus the 134 pound mark of 5 years ago).
Another fear is that we won't feel as good with this type of workout. It is true that high impact delivers a huge dose of endorphins. No getting around that. But, you can still feel phenomenally "high" and worked out after a low impact workout. When I got off the treadmill yesterday after my inclines workout, there was more sweat on me than on most of the people working on cardio machines near me and as much sweat as the two guys running either side of me. We all three completed 4 miles worth, just at different speeds. So what? I climbed mountains during my workout!
The trick is to change your perception so that you are as satisfied and recharged by the low impact as by the high. Don't think you can't challenge yourself just because it's low impact. For me, the challenge comes from power walking for longer at the higher speeds or at the higher inclines. If you do kickbox, the challenge will come from "crisping up" those punches and kicks, making the kick and punch that much "punchier" and never delivering a wimpy, half-assed punch or kick. After all, what would be the point? If you do Low Max, the challenge will be in not taking any catch-my-breath breaks, and in going lower in all the moves and higher in all the moves, with a larger range of motion, etc.
Once you get over yourself and realize that what you are doing by switching to low impact for a while is actually going to be better for you and will improve your health, you can make new goals, and the intense satisfaction from your new workouts will come from achieving those goals.
Since I am doing so much low impact at the moment, I am less wiped out by it than by my running and am able to do 1-1 1/2 hour lower body and core training sessions right after it at the gym. This means I am able to do more of the specific training moves my knees and hips need to protect them when I get back to running and also allows me more days off during the week because I can get all my exercise done on 3 or 4 workout days per week, which better suits my timetable and low boredom thresholds.
Low impact can work for you. Take a look through your DVD library and pick out all the DVDs that lend themselves to low impact. Build a new routine for a while. Pour through magazines and tear out some great circuit workouts from them to try at home or at gym, and use this time also to get more yoga-pilates into your routine. This new shift and emphasis in your workouts could lead to long term improved health by leading you to take better care of your joints to prevent injury again. Promise!
You know, there is a type of very intense workout that combines cardio and weight training all in one, that burns tons of calories and is largely/totally low impact that you could try now: kettlebells. Perhaps now is the time to try a totally different approach to working out?
