62.        In this argument the author concludes that the new community fitness center
should be equipped with the state-of-the-art exercise machines featured in Powerflex
magazine. In support of this recommendation two reasons are offered: (1) Powerflex
contains pictures of bodybuilders using such machines, and (2) Powerflex is a popular
magazine, as evidenced by the fact that it frequently sells out at the local newsstand.
This argument is questionable on two counts.
      First, a major implication of the argument is that the bodybuilders pictured using
the machines in Powerflex magazine reached their state of fitness as a result of using
these machines. The only evidence offered to support this contention, however, is the
pictures in the magazine. It is possible that the bodybuilders pictured use different
equipment for their workouts and are merely posing with the machines for advertising
purposes.
      Second, the author assumes that machines that are suitable for bodybuilding will
also be suitable to help maximize the fitness levels of the town's residents. This
assumption is highly questionable. Machines designed to increase muscle development
are significantly different from those designed to increase cardiovascular fitness.
Consequently, it is unlikely that the machines pictured in the magazine will be of much
use to help maximize the fitness levels of the town's residents.
      In conclusion, this argument is unconvincing. To strengthen the argument the
author would have to show that the bodybuilders pictured using the exercise machines
actually used the machines to reach their level of muscle development. Additionally, the
author would have to show that the machines were suitable for increasing the fitness
levels of the persons using them.
