Set the treadmill to 1 to 2 mph, then walk behind the treadmill and get into a crab position. Place your hands on the side of the treadmill base, facing away from the treadmill and with your back facing the ground. Keeping your feet flat on the floor and your hips elevated, place your hands on the treadmill belt and walk your hands forward.
Stop the treadmill, and pull the emergency tag. Stand on the treadmill, and gripping the handles with both hands and keeping your elbows slightly bent, drive your legs forward so that you push the treadmill belt back with your feet.
Turn the treadmill off, and stand on the side base of the treadmill, with your hands on the top of the treadmill’s handles. Your body should form a straight line from your heels to your head. Bend your elbows to perform a pushup, bringing your chest all the way down to touch the bars/console of the treadmill. Pause, then push back up. To focus on your triceps, keep your elbows tighter to the sides of your body.
