Defined Strength Precision Leg Extension

The Defined Strength Precision Range Leg Extension is a premium lower-body isolation machine designed to target the quadriceps with unmatched precision, comfort, and control. Engineered to deliver smooth resistance through a full range of motion, it allows users to develop strength and size in the quads with reduced joint stress and superior mechanical alignment.

Featuring an adjustable back pad, seat angle, and shin pad, the machine ensures proper knee positioning and optimal resistance delivery across all leg lengths and body types. The contoured seat and ergonomic support promote strict form and minimize hip engagement, placing full emphasis on the quadriceps throughout the lift.

Equipped with Smart Strength Technology, the Precision Range Leg Extension allows users to shift the resistance profile—overloading the movement’s beginning, middle, or peak contraction phase. This level of customization supports targeted hypertrophy, strength progression, and rehabilitation work, all while enhancing the user’s mind-muscle connection.

The pin-loaded resistance stack offers fast and seamless weight adjustments, ideal for drop sets, circuits, or time-efficient training. Built from a heavy-duty tubular steel frame, with reinforced bearings and commercial-grade padding, the machine ensures long-term durability and high performance in any gym setting.

With a space-efficient footprint—measuring 145 cm in length, 110 cm in width, and 140 cm in height—and a total weight of 185 kg, the Precision Range Leg Extension is a cornerstone piece for lower-body training in both commercial and athletic performance environments.

In summary, the Defined Strength Precision Range Leg Extension delivers anatomical precision, intelligent resistance variability, and elite build quality—making it an essential machine for effective and focused quadriceps development.
