The EPRI heavy-duty exercise ball http://www.amazon.com/gp/product/B0016L8Q3A http://www.amazon.com/gp/product/B0016L8Q3A works pretty well, and is only $40 or so. It keeps you moving slightly (bouncing, rolling), which is good for us autistic types who'd otherwise be jiggling a knee, etc.
- tumult 18y agoDude, I dare you to get your sitzfleisch on for 12 hours at a time with an exercise ball. Get real.
- arebop 18y agoI've used it for maybe six hour intervals with no noticeable problems.
- silentbicycle 18y agoSitzfleish is a great word.
