Jaysis! I've seen people RUN up this thing and it makes me want to dropkick them.
You start out on about a 45-50 degree incline (I honestly don't think I'm exaggerating this at all), and after you're legs are good and burny, the ultra-steep winding steps begin. If you're doing this for fitness, and not a dare, doing a couple push-ups on the benches here isn't a bad idea - gives your legs a short rest, keeps the blood moving and works an extra set of muscles.
Once you make it to the top of the stairs, you have a wonderful view of Tempe - which might be why not to many people linger at the top longer than necessary.
Your legs WILL wobble on the way down - take it slow if you have to. If your legs don't feel like jello, then you need to stop working out and give the rest of us poor schlubs a chance.
Oh - 3 stars because it makes me feel inadequate. Nyah.
