This is probably a weird place to ask this, but I've never really been into any serious kinds of exercise, so I don't really have any dedicated forum to frequent. Figured I'd begin here for advice, and see where it takes me.
First off, I think it's important to know a few things about me. Firstly, I'm overweight, lazy, and out of shape (obviously). I'm not morbidly obese by any means, but I'm 6'2 and 215 pounds which is mostly in my gut. So I could stand to lose some. Secondly, and most importantly, I just found out 6 months ago that I have a muscle disorder. Some type of metabolic myopathy (still haven't found out for sure what it is yet). Maybe something along the lines of McArdle's Disease, which is a type of Glycogen Storage Disease. This is very important to keep in mind, as I have a really hard time exercising without hurting myself. I've often tried to work out with weights, and almost every time it ends with me causing a muscle to swell up, and then an hour later my urine will come out almost black, and really foamy. Which means I'm having muscle death on account of my exercising due to my muscle disorder, and can lead to kidney damage, or even acute renal failure if I'm no careful and it happens too often.
So, having said all that, I'm trying to find some sort of light training program (preferably with no weights) that will give me cardio, and a stronger core, but that won't completely wreck my legs and feet (as those are usually the first few muscles to go on me, and get really swollen, and then the dark urine happens, which is real bad, etc, etc.). Running is kinda out. I can do walking, but it eventually leads to my calves/feet/thighs hurting if I do it for too long... I've been looking into Pilates. That seems like something that might fall into line with what I need. It's not a ton of being on my feet. It's not running (which I have a hard time with) or weight-lifting (which always seems to end up hurting me really bad), but I don't really know where to start since there are so many different types of Pilates exercises.
The most ideal scenario as far as where, and how I do whatever exercise would be with something on TV in my living room. I need to be TOLD what to do. If I'm left to my own I have a hard time making myself memorize exercises, and continue to do them. If I have someone telling me what to do every step of the way, I tend to stick with it. So I'm thinking a DVD I could put on the TV every day would be great.
Basically, I'm looking for any advice on how to exercise in a way that works with my muscle disorder, and doesn't cause it to flare up. It doesn't have to be Pilates. I'm open to any suggestions. The doctor just told me to keep it really light, but that I do NEED to do some exercise (especially cardio) even though I have this muscular problem. He said if I don't, I'll be a prime candidate for a stroke or heart attack sooner, rather than later, and I'm only 28. I'm young. I have a wife. Needless to say, I don't want that to happen.
Thanks in advance!
