I've been following this thread for awhile, and I too wonder about the strenuous workouts Nikki. My husband is purely LMN so far. He tends to overdo things, 1) because it is habit, 2). because he wants to remain useful & 3) because he is stubborn. I really do empathize with his way of looking at things, and truth be told, if it were me with this wretched disease, I would probably be even more stubborn / push the limits for awhile. I have basically told my husband he has to take very frequent rest breaks ..... that he has all day. I think I may have gotten him used to the idea that doing gentle exercise (light resistance like #2 or #3) if he wants is o.k., BUT, he has to rethink the old ideas about "3 sets of 10" or "3 sets 'til fatigue". Mostly I have him doing range of motion exercises, but with pauses using the weight of the limb as resistance (which is still quite substantial for most people). I also tell him I don't want him to feel fatigue with any exercise - "do 3 - 5 reps and then rest 3 min", etc. My thinking about this is that a person with ALS should not work to fatigue. You can still work the muscles gently and take very frequent breaks, etc. Just the act of walking around during the day and doing "normal tasks" works the muscles for those still able to do so. Just standing upright, trying to focus on good posture while tightening your buttocks and thigh muscle involves a tremendous amount of muscles ...... those of us able to do this with ease just don't think much about it. What Bear says above is great (IMO) ... "just keep moving" is working best for me....if I can left my arm or arms up and down a few times then I do it. Same for any other part......I just keep the brain-nerve connection maintained and send the fluids to the muscles when exercised.....I cannot see how this could not be beneficial....if for a "normal" person, if you don't exercise you will naturally atrophy".
