I know what you mean by the hot weather making you feel sick. I have been farm setting a sick alpaca, a horse with a serious hoof problem who just had surgery, 4 dogs & chickens. The barn aisle where I was cleaning the stall had no air flow. I sweat so bad it made my glasses impossible to see through. I was dehydrating so bad I brought a mug of water with crushed ice that I guzzled just to keep from passing out 90F with 95% humidity. I hate weighing myself after drinking so much because I always drink more than I sweat out. I couldn't find my sweat band but found my cool cloth I watered down & kept around my neck. It helped a little but it's difficult to be active in heat like that without overheating.

I came home & just crashed then woke up feeling horrible but pushed myself to shower & head to my intermediate ballroom dance class. The room was air conditioned but because my body had been so out of whack from the heat earlier, I was overheating 1/2 way through the class.

I bought one of those rebounder trampolines. They are supposed to be low impact for my knee that was reconstructed in my late 30's after blowing out my ACL in a racquetball injury. Lol, I was playing an A player on the challenge court & blew out my ACL on my winning point....couldn't even defend my victory. After working in the barn, I realized that the area in my back where I had a compression fracture a 4 years ago was bothering me. Think this rebounding will help me get in better shape & help with my ballroom dance stamina & form.

I'm trying to find healthy low impact exercise I can keep up through the winter. When my weight was really low, so was my blood pressure. Now I'm at a more healthy weight, my blood pressure is going up. Have read research that rebounding is also good for lowering blood pressure & keeping the lymphatic system healthy also.

It will also keep any weight gain under control when I work up to the time that gives good aerobic exercise. Have to do something easy that takes just a little time during the day with max benefit.
