The first was a self-propelled treadmill. Instead of having a motor that drives the belt, the motion of the user's feet drives the belt. This means that it adjusts automatically to the user's speed and stride length, which I found was both an advantage and a disadvantage. Lengthen your stride a bit, and you can suddenly find the belt going a lot faster. I think it'll actually take a bit of practice for me to be able to run at a nice steady pace on one.
The second was a VersaClimber. Which is a bit like a stair-stepping machine, but with handles that you can grab so that it sort of mimics the motion of climbing a ladder. This is potentially a great full body aerobic workout and great cross-training for climbing if I can get the hang of it. Keeping your body stable on a machine where all four of your limbs are hanging on to things that are moving requires both coordination and core strength, which are not things I have in abundance. I'll have to practice with it.
They opened the new fitness area before they actually moved anyone into the offices in the building it's in, so right now it's also blessedly uncrowded. I figure I ought to be able to enjoy at least a couple of weeks of being able to VersaClimb to my heart's content before everyone else figures out it's here.
