Suggestions for a hypotonic college student?

I haven't tried water aerobics, but I suspect they wouldn't work for the same reason swimming doesn't - I forgot to say it originally, but I also have developmental dyspraxia, and so I have trouble with things that require coordinating different parts of my body to work together. So, I am not really coordinated enough to swim long distances or tread water too well, and jumping jacks require concentration. There's also the fact that I currently only own the bottom half of a swimsuit, but that will hopefully be fixed before the end of the summer anyway.

I do like walking, especially when my sister comes along. And walking around campus is fun, since there are redwoods, and enough hills that it takes a bit of effort. But I get bored sometimes when I am alone, and I just can't walk enough to work off my extra energy. I literally have to walk at a moderate pace for around three hours straight to get tired, even though I can't run for more than two minutes (my lungs hurt too much).

Also, no. My therapist didn't give me any suggestions. I actually haven't seen her in a couple years, because she doesn't work with people past 18. But the last time I saw her, she said that she was really worried about me, and that she thought I needed to do SOMETHING to exercise more, and she didn't really care what as long as I didn't hurt myself.

I also used to do ice skating (just around the edge of the rink), but I could only ever do that once a week, and where I live now, there are no skating rinks. I've tried roller skating instead, but found that it was harder for me, as I had more trouble balancing and stopping without falling on my butt.

Sorry if this makes no sense...

@Pamelaamarsha - thanks! the second set of videos looks like it might be worth trying. And my sister said the same thing about dumbells, lol. I don't want to exercise for weight loss, really, although it's a nice bonus. I more want to exercise because I get so restless and jittery if I don't (which right now is a lot of the time). Thanks for the help.

It's not genetic, as far as they can tell. I am also autistic and have a sensory processing disorder that was pretty severe when I was a child. Hypotonia and dyspraxia are pretty common to go along with both of those things, so I think it's reasonable to assume that there is nothing horribly wrong.

Unfortunately, while my college's disabled student services are great, the medical center is useless for the kind of stuff I would need. And honestly, while more therapy would be nice in some ways, I'm not really certain how useful or necessary it is, even if I could find a therapist. I am mostly good on everyday life activities now. I just need to figure out something better than walking for exercise, so that I can be healthier and not as hyperactive.
