   bringing into play any secondary leg muscles.

Due to its inherent design the knee joint remains
   aligned with the pivoting axis..

Specifically designed R.O.M for constant work load

The moving member's specific curvature ensures perfectly
   symmetrical load on hamstrings while minimizing knee strain.

Self Aligning roller for foot alignment.

The upper two knee rollers ensure user lock down during
   exercise & releases to facilitate ease of entry & exit.

Reclined seat back angle prevents quadriceps from interfering
