I'm working out on the gym and I just recently started using the stair climber. Boy, is it ever a hard workout! I show you me working out and getting sweatier and sweatier, with closeup views of my face. You'll also see me wiping away my excess sweat with paper towels and then showing you the paper towels-yuck! I get so nasty and sweaty on the stair climber-I can tell it's a super effective workout! I feel so gross when I'm done that I absolutely have to hit the showers ASAP!
