LegFlexx Manual v1.0.0

Warning

During use

Personal injuries may occur if the relevant precautions are not observed. 

• 

Work out at a submaximal** intensity until you are familiar with the equipment.

• 

Keep away from moving and/or rotating parts.

• 

Keep hands on side handles during exercise.

• 

Never adjust the drive belt when the flywheel spins.

• 

Never stop a spinning flywheel with your bare hand or bare foot as it may cause friction burns.

• 

Do not let the moving arm (swing beam) hit the LegFlexx, absorb the eccentric load before it hits the foam 
bumper.

• 

If you feel dizzy or experience pain, stop exercising immediately. 

• 

Never get up from the LegFlexx while the flywheels are moving. Make sure the flywheels have come to a 
complete stop before you end the exercise and step off.

• 

Exercising at maximum intensity may cause temporary staggering and uncontrolled body movements due to 
fatigue. Exercise caution to prevent falling.

• 

Exxentric takes no responsibility for any injuries that may occur while using this product.

For Your Safety

Please read and understand the user manual and warning labels prior to use.

 

• 

Inspect the machine including the drive belt before use. Damaged or worn parts and warning labels 

must

 be 

replaced. See user manual for how to change and cut the drive belt. Do not modify the machine or repair it 
with non OEM parts.

• 

Always place the LegFlexx upright on level ground or on a floor surface.

• 

When performing assisted overload exercises the machine should be fixed to the ground.

• 

Flywheels may get slippery when wet. When lifting flywheels, use a secure two-handed grip.

• 

The machine and accessories are intended for strength training only. Do not use it in any other way.

• 

The LegFlexx can deliver a supramaximal* workload. Do not exercise at an intensity above your physical 
capacity.

• 

The device is not suitable for children or animals. 

WARNING

*) Supramaximal means higher than maximal. This means higher loads than your muscles can produce 

themselves in a shortening (concentric) action.

**) Submaximal means below maximal. In this case, we would recommend below 75% of maximum intensity.
