Query: Won't fit the regular Joe's arm

I'm 5'9" and 150 lbs, and this product just won't fit tightly in my arm. I have the 60 GB iPod and even without exercise, it starts slipping down in about two minutes.If you have a 60GB iPod, I'm not sure there are other options. Anyway, I am returning this product.
