TRUE Inner Outer Thigh (FS52R-19)

The TRUE FS52R-19 Inner/Outer Thigh Machine is a dual-function commercial selectorised machine that trains the hip adductors (inner thigh) and hip abductors (outer thigh) in guided, isolated movements from the same seated station. The dual-function design eliminates the need for two separate machines, providing both movement patterns from a single unit that requires minimal adjustment to switch between functions.

The hip adductors — gracilis, adductor magnus, adductor longus, adductor brevis, and pectineus — are functionally important in lateral stability during walking, running, and jumping, and are frequently weak relative to the hip abductors in both sedentary populations and in certain athlete groups. Isolated adductor training on the FS52R-19 allows direct, measurable strengthening of these muscles with resistance levels appropriate to their relative strength capacity.

The hip abductors — gluteus medius, gluteus minimus, and tensor fasciae latae — are critical stabilisers of the pelvis during single-leg loading phases in walking and running. Weakness of these muscles is associated with Trendelenburg gait, iliotibial band syndrome, and patellofemoral pain. The FS52R-19's abduction movement provides direct training of these muscles in a guided, load-controlled environment that is safe and appropriate for rehabilitation and prevention programming.

TRUE has constructed the FS52R-19 to commercial standards, with a welded steel frame, adjustable pad positioning to accommodate users of different leg lengths and seat-to-pad distance preferences, and a selectorised weight stack with clear incremental markings for progressive loading.

The machine's comfortable, ergonomically contoured seat and leg pad system minimises discomfort during the loaded range of motion, encouraging members to complete full-range repetitions and maintain consistent training frequency across their programme.
