The S-Line Leg Extension sits between the C-Line (53\"×49\", 575 lb, contact for stack) and the Discovery Series Leg Extension (53\"×49\", 575 lb, 240 lb + add-on) in the Precor selectorized leg extension line — sharing the same functional training objective with a distinct frame and footprint. At 50\"×43\" and 477 lb, the S-Line is the narrowest and lightest of the three, with 6\" less width and approximately 100 lb less frame weight, making it appropriate for facilities where the 49\" width of the C-Line and Discovery variants is a layout constraint. The adjustable starting position is the leg extension specification that determines whether the machine fits the user's anatomy: the start position sets the knee angle at which the extension begins. If the starting position is too far into flexion for the user's flexibility or injury history, the user cannot sit in the correct position without compensatory torso forward lean; if it's not far enough, the extension arc begins outside the muscle's productive range. Adjustable starting position accommodates the full population from rehabilitation (shallow starting angle) through performance (deeper flexion start for greater stretch-mediated loading). The ergonomic seat and backrest maintain the pelvis in a neutral position throughout the extension arc — pelvis stability is what keeps the hip flexors from assisting the extension movement and diluting the quad isolation.\u003c\/p\u003e\n\u003cp class=\"bs-desc\"\u003eCompact 50\"×43\" footprint for space-efficient lower body programming. \u003cstrong\u003e477 lb Precor S-Line commercial frame\u003c\/strong\u003e.
