THEORY OF OPERATION
The Lifecycles recumbent bikes are stationary exercise bicycles that provide a scientific method of improving body
fitness and endurance through its unique “12 or 24 MINUTE RIDE TO VIGOROUS HEALTH.”
Computerized state-of-the-art electronics have been engineered to satisfy a range of personalized fitness needs of
the beginner to the needs of the most advanced fitness enthusiast.
The Lifecycle concept is based on the self-motivational principle of INTERVAL TRAINING WITH PROGRESSIVE
OVERLOAD. During the HILL and RANDOM exercise programs, the workload against which you are pedaling is
periodically changed by the built-in computer resulting in an automatic increase or decrease in pedal resistance.
This simulates riding up and down virtual “hills,” which are visualized on the display console with columns of “lights”
that move from right to left.
With features like the RACE program, Fit Test, level 0 resistance - almost 25% easier than the level 1 found on
earlier editions of the classic Lifecycle exercise bike - and exciting variable-ergonomic handlebars, you’ll be much
more likely to stick with your exercise plan and accomplish your goals.
The ability to select a program to match your particular needs is what distinguishes Lifecycle bikes as the world’s
most popular physical conditioning device. Its user-flexibility means that you will never outgrow the innumerable
challenges the Lifecycle exercise bike has to offer.
The beginner starts with basic programs, then improves his level of fitness at his own rate while constantly
challenging himself to the next level. For well-conditioned individuals, the advanced programs offer more difficult
modes of training. In fact, many world-class athletes use Lifecycle bikes to maintain peak levels of conditioning.
The Lifecycle bike is an extremely rugged exercise bicycle that is designed to withstand heavy use for many years.
During its two-year research and development phase, prototype Lifecycles were placed in high-volume health clubs
and fitness centers across the United States where they were field tested for up to 18 hours a day.
