That statement is not entirely true. Yes, treadmill is a dirty word, but ... treadmills add a lot of variety to training when used not only for dips but as wheelbarrows too. First, choose the treadmill with the correct load (depending on the fattitude of the person on said treadmill). Then, pick up the back (the wheels are usually on the front) and RUN with it. Woohoo!
Be prepared to loose (for you, Shugart) your gym membership.
