Kneeling Leg Curl.

The stretch is there before you begin.

A lying curl starts with fairly relaxed hamstrings, and the first degrees of the movement give little back. Kneeling, the hip is flexed, so the muscle is already under stretch when you start, and then you work from the first degree instead of from halfway. The support pad locks the hip so you cannot extend the movement with a throw when it starts to burn, and each leg has its own lever. The machine measures 1515 × 1205 × 1390 mm, weighs 109 kg and loads with Olympic plates (Ø50 mm). No free degrees.
