7. Fly off the treadmill.

How-To: One word – Zoomers. Mess this baby up and it’s the fastest route to becoming a human skid mark I know of. My other failsafe way to fall off the treadmill is to get into a really good conversation with Gym Buddy Allison who is on the treadmill next to me, slowly drift to one side of the ‘mill because I’m not looking forward and then – whammo – off I go.

Quick Fix: Stand up, throw up your arms and present to the judges. 10 points for blood.
