RESISTANCE OVERVIEW 

The Keiser M3/M3+ is a revolutionary new way to exercise, with a focus on Power Output. 

The understanding of the resistance system can best be described in the explanation of 

eddy current resistance and the formula for Power: (Power = Force x Velocity).

 

An eddy current is an electrical current in a conducting material that results from induction by 

a moving or varying magnetic field. On the M3/M3+, this is generated by the wheel passing 

through two opposing magnets. The flywheel (a conductor) passes through the magnetic field 

generated by the two powerful magnets. By varying how much of the magnetic field comes into 

contact with the flywheel, the amount of resistance will increase or decrease for the user. This  

resistance system also allows the participant a smoother, quieter, and more predictable workout. 

 

If the flywheel is in less contact with the magnetic field, it is easier to operate. The more 

of the flywheel that comes in contact with the magnetic field (the higher the energy that is 

being generated with each turn) the more difficult it becomes to operate.

 

Another major factor that plays a role in resistance is speed. The faster the flywheel turns, 

the more energy is generated, and thus the more resistance is created.
Power (amount of work being done in a given amount of time by the participant) = Force 

(the amount of resistance) x Velocity (the Cadence the user is striding). This is the same 

formula that occurs naturally. By moving faster the difficultly increases as the resistance 

increases. The same applies to the M3/M3+, at a set Gear the resistance can be increased 

or decreased by adjusting the participants speed. 
In this way the M3/M3+ is very similar to natural movement. The higher the Gear, the higher 

the Cadence the more Power produced.
