Marketer: While running is one of the most efficient forms of exercise for losing weight, many would-be runners are unable to participate due to the joint pain – particularly in knees and ankles – that they experience while running. With our reduced-gravity treadmill, these people can derive the full weight-loss benefit of running without the intense joint pain.

Which of the following, if true, would most weaken the argument above?

(A) Most avid runners greatly prefer running outdoors to running on a machine.

(B) Experts believe that swimming, not running, is the most effective form of exercise for those looking to lose weight.

(C) A reduced-gravity treadmill can alter one’s natural running stride, leaning to muscle and tendon strain issues.

(D) While reduced gravity can lessen the severity of joint pain, those who experience pain from prior injuries will likely feel some joint pain while using a reduced-gravity
treadmill.

(E) Much of the weight-loss benefit from running is derived from a runner having to carry his own body weight across a long distance.
