I second the elastic band that's what my physical therapist is having me use. I also go on nature walks (if you can) it's nice to get fresh air and get a little cardio but I literally walk around my house so I can lay in the grass in case of dizziness

I'm in PT for POTS to build up a routine but it got put on temporary hold bc my iron level is almost zero, so they are waiting til I get iron infusions bc can't exercise with no iron (my FE level has been 4, my iron 6, 3% sat - super anemic just took them 7 months to decide to act on it bc I have HH too).

there’s a girl on tiktok that shows workouts you can do from your bed if you can’t find the energy or strength to get out. i also really love just doing yoga in my room. i can make it as difficult or slow and easy as i want it to be or watch a video or make up my own transitions. it feels really good to just stretch and move without putting too much stress on my body
