Got mine from TARGET for a spinning class. Sitting on a hard surface will not make the gluteals firmer. The only thing that makes muscles stronger is contraction and relaxation. Unless science has come up with something else I've never heard of.
lol I find it amusing how in like 90% of the topless boy pics you've posted (that Iv'e seen at least) their underwear alway slook too big or ill-fitted or something
i theoretically know all about the muscles that may be found anywhere in the ass region :H still, i have no idea what bike seats do to them...
Shes prob talking about the pictures of = The Byrds a classic Band and a icon of the 1960s but she prob think they came from MTV
