LegExx

Leg Extension

Unlike the kBox and kPulley multi-exercise devices, the LegExx sole purpose is to target the quadriceps muscle. Since the LegExx is built on the same scientifically-proven flywheel technology, it ensures maximized hypertrophy by providing 100% muscle stimulation in the quadriceps. With the same flywheel-feeling.

For injured or low mobility users (e.g. in the ACL rehab process), you can get strength gains in the quadriceps without having to worry about posture or complex multi-joint movements or overcompensating with other muscles, such as the glutes when doing squats.

Variations

The LegExx extension can be performed with restricted ROM, 2-1 overload option, self- and spotter-assisted overload using the kGrip attachment. The LegExx ensures a safe and maximal muscle stimulation in the quadriceps ensuring an effective workout without previous training knowledge.

Self- and spotter-assisted Overload:

Performed using the kGrip.

 

 

 

 

 

 

2-1 overload:

Performed by using two feet up in the concentric phase, resist with one foot in the eccentric phase.

 

 

 

 

 

 

 

Restricted ROM:

To ensure a rehabilitation patient restricts their ROM in the bottom position of a leg extension, the LegExx moving arm can be strapped with an attachment band to lock it into a desirable ending position. Caution! Read the user manual before attempting this LegExx extension variation to ensure correct execution.
