As most readers are aware, back in 2004 I was seriously injured in a work-related accident. After two surgeries, culminating in a spinal fusion, I ended up with a damaged left sciatic nerve, and in pain 24/7/365. I can keep the latter under control if I work at it, and use pain-killers when needed, but it's no fun. It's restricted my mobility, so that I can't walk too far without needing a stick, and not much further before I have to sit down and let the pain subside before going on. Running is out of the question, and my sense of balance is also affected, so that cycling (on roads, anyway) can be tricky.
Another result of the injury was that my neurosurgeon told me I'm restricted to carrying not more than 25 pounds for the rest of my life. I'm afraid I've honored that more in the breach than in the observance on occasion (try moving house carrying only 25 pounds at a time!), but generally the pain issue has helped forced me to observe it more-or-less faithfully. I'd hoped to do more strength training to compensate for the enforced lack of aerobic exercise (see preceding paragraph), but found that I simply couldn't tolerate very much weight on a barbell before my back went on strike and started hurting me badly. To add to my difficulties, over time I've developed arthritis in my spine, which I'm told is a normal side-effect after a spinal fusion. It adds to the pain burden and further restricts flexibility.
I've been struggling to find a "middle way", some form of exercise that can help keep me a little fitter than a jellyfish, but won't trigger my pain reflex or mobility issues. I've been working out with dumbbells rather than barbells, because a dumbbell doesn't rest on my shoulders or neck or spine, making it less stressful. I can add weight to a pair of dumbbells, as heavy as my restrictions will allow, and use them in movement exercises to keep my muscles in trim. (There are lots of exercises that use them.) I haven't tried kettlebells to any great extent yet, but may do so soon. (On the other hand, is it worth using kettlebells when one's already using dumbbells? Will readers with experience of both comment, please?)
I'm trying to combine dumbbells with step training. The latter has been used for decades as a conditioning exercise for new workers on South African mines, and I'm familiar with the way they do (or did) it. I can't do it for long periods or at high intensity, but I can manage a few steps up and down while using a dumbbell in various exercises, then take a break before doing it again. (I seem to use a lot more weight on my dumbbells than is seen in most videos of step exercises. Those things are tiny!) I hope the added workout will help my cardiovascular health to at least some extent.
Are there any other alternatives for someone in my position? I'd appreciate suggestions from readers, please. I don't want to die because I've become an unfit slob, but compared to most people my age, that's what I am, because I can't exercise anything like as hard or as fast as they do. If you can offer suggestions, please do so in Comments.
Thanks.
