I try to walk rather than use the car for normal errands. It all adds up and I think this makes a big difference. If I'm struggling a bit with POTS, I restrict this to walking where it's flat and do less. If I'm feeling a bit better, I can manage some inclines and perhaps carrying a bit of shopping. If I'm having a good patch healthwise, I try to go to the gym. I like the fact that it's a safe environment (if I suddenly feel ill, I can have a lie down) and it's air conditioned. I do about 10mins on a cardio machine (eg, reclining bike, walking on the treadmill, rowing machine) and then some resistance work on the weight machines. I usually stay about 45 minutes alternating between the two and if I feel I can just manage another turn on a cardio machine, it's time to go home. My tip is to leave some energy in reserve - this seems to prevent a POTS crash later in the day/the next morning. I have tried all sorts of aerobics classes and sports but find it best if I go to the gym so I go at my pace and I am not tempted to overdo it. I also found that the gradual cool down in aerobics classes was unbearable (my HR stayed high whilst we moved less and less resulting in a recipe for fainting) so find a way to get your HR down safely to avoid the post-exercise crash. My strategy is not one you would find in a fitness textbook, but it works for me. If you can find a suitable yoga class (ie, one that mainly involves sitting poses), that can be enjoyable and relaxing. I know that some forum members are too ill to contemplate this sort of exercise. I have never been so ill that I've needed to use a wheelchair or similar aids. My comments come from 20+ years of experience of POTS varying from "needing much bed-rest but can more or less look after myself" to having a "POTS-modified, but near normal life". Please do not be tempted to do too much too soon or set yourself rigid targets - just do whatever you can. P.S. A few things I find best to avoid 1. Exercise in the morning. 2. Cross training machines (and anything else that involves standing relatively still whilst exercising arms and legs at the same time eg, step aerobics, aqua aerobics). 3. I often see the media saying that however tired you feel, you will always feel better if you exercise. Sorry, but that just isn't true for me. If I feel rough, exercising makes me worse so I avoid formal exercise until I've got a bit better.
