Pro: Top-of-the-line. Unparalleled. Unmatched. This is the embodiment of the Life Fitness Strength Pro Series.
Superior upper body, lower body, and multi-use selectorized machines that deliver unequalled exercise variety and
performance — day in, day out. Built to last, this complete line offering is engineered with the expertise that has
made Life Fitness a global leader in advanced strength equipment. For maximum results, more exercise options,
and a facility that nearly runs itself, choose Pro Series. Unstoppable performance beyond all boundaries.

With over 60,000 machines installed worldwide, Life Fitness Pro Series has proven itself in the
most demanding situations. Our unbeatable reliability comes from using only the highest
quality components. Stainless steel in high-wear areas to eliminate rusting, thermoplastic rubber
grips for extreme durability, and internally lubricated cables to ensure long life. Our
self-lubricating weight stacks use sealed bearings to guarantee quiet and smooth use. All of this
results in the most high-performance, low-maintenance selectorized product available.

Precision engineered components and systems make Life Fitness Pro Series compatible with every exerciser. Workouts
are smooth and simple with quick and hassle-free adjustments, most of which can be performed right from the exercise
position. The Quick Click™ seat adjustment easily slides in 1/2" increments for a precise
fit, while the new input length adjustment on some lower body machines utilizes a balanced four-bar linkage to allow easy, onehand
pad adjustments. Our precision technologies are precisely what you and your exercisers are looking for.

It's the thought behind the design that makes Life Fitness Pro Series so popular with users. Every product feels right because we've done our homework to build
the ultimate combination of superior biomechanics, ergonomics, and easy-to-use features. Our machines provide the
broadest appeal with low starting resistance, minimal adjustments, and easyto- follow instructional placards for workouts
that invite beginners yet challenge the toughest users.
