Hazeldazel...HILARIOUS! I love that tune
I pay $10 at a supplement store in my neighborhood. You should not have eaten 3 hours before (as well as water), wear a bathing suit (nothing baggy), and that's it. If you have a swim cap to bring it helps (and don't worry...you don't get wet)
And YES...I have read many posts about the step-ups and must say that my legs aren't looking forward to it...hee-hee! Maybe I should post about my pain now since I know it's coming...LOL!
