i just bought a stepco. step at Sam's Club ($39.95) and between the sound of my steps on it and it creaking, it seems so loud. I work out in my basement at 5:00a.m. and since it's so quiet, I am afraid I will wake everyone with my noisy stepping and creaking! Are there any suggestions? I thought about putting it on a rug or something, but I thought it might slip causing me to fall. It may just be normal, but my old step was homemade out of plywood with a piece of carpet nailed to the top. I used it for 10 years! Worked great, but obviously there were no heght adjustments & it wasn't long enough for many of Cathe's moves. Any thoughts?
