WHAT IS THE STAIRMASTER CROSSROBICS 1650 LE
CONDITIONING SYSTEM?
The Crossrobics 1650 LE conditioning system is a non weight-bearing, weight-
loading, exercise system. Regular use produces increased aerobic capacity as
well as stronger muscles and bones. Traditional types of weight-loading
exercise, such as weight lifting, produce stronger muscles and bones but
cannot be performed in the rhythmic, continuous fashion needed to improve
aerobic fitness. Traditional weight-bearing exercise, such as jogging, improves
aerobic fitness, but does little to enhance muscular strength. This type of
exercise also increases a user's risk of injury by placing high impact forces on
their joints.
The difference between the Crossrobics 1650 LE conditioning system
and other types of exercise is the patented Crossrobics loading system. The
Crossrobics loading system allows the user independent control of both speed
level and resistance. The exercise speed is controlled with the FASTER and
SLOWER keys on the console. The resistance is controlled by selecting the
appropriate number of plates on the weight stack.
The training emphasis of any given workout depends on how the two
variables, speed level and resistance, are combined (see The Crossrobics
Conditioning Matrix Table
exercise speeds and heavier resistance. A power workout combines faster
exercise speeds and heavy resistance. Fast exercise speeds and lighter
resistance improve leg speed. An endurance program using slower speeds
and lighter weights is ideal for the long-duration workouts recommended by
weight-control experts.
