what is a good brand of exercise ball that i can sit on while i work at my desk? what size do i need? i am 6 foot tall. i see a bunch of different ones on amazon.com.
I don't really think one brand is better than another. Between mine and the ones I've used at the gym I haven't noticed a difference. I think I got mine at Ulta, but they also sell them at Target and Academy. You should probably get a large one. I love my exercise ball. There are a ton of cool exercises that you can do with one besides just sitting on it.
actually i'm not joking. i want one. i did not realize i could sit at my computer for 10 hours a day and end up looking like chuck norris.
I still love my excercise ball! But unlike wankers and Chuck Norris, I don't sit on mine at the office.
po: if you are 6' tall, get the 75cm. that is, if you are just going to use it to sit on. you will need a smaller one if you are going to do most prone exercises properly. go toThe Link and get the resist-a-ball. that will be adequate.
