Dear 100 Hour Board,
I consider myself a relatively healthy person. I ride my bike to work and class every day, I can do some pretty god hiking, etc. However, I am pretty winded after ascending flights of steps. Why is this? How come I can do other sorts of exercise without a problem?

A: Dear Spike,
Climbing stairs uses different muscles than riding a bike or walking on semi-level surfaces. So your quads probably aren't used to doing that much lifting. Climbing stairs is actually hard work because you're constantly lifting your own body weight. We're used to doing it in small spurts, but when it becomes an aerobic activity we start huffing and puffing. Besides, quads are some of the largest muscles in your body, they need a lot of oxygen.
