The Impulse IF9308 Inner and Outer Thigh Combo machine is designed to target and strengthen key muscles in the lower limbs including the vastus lateralis, gluteus maximus, adductor magnus, and rectus femoris. This versatile equipment allows users to perform exercises that engage both the inner and outer thigh muscles through adduction and abduction movements. The vastus lateralis, part of the quadriceps group, is worked during knee extension, while the gluteus maximus contributes to hip extension and thigh abduction. The adductor magnus assists in thigh adduction, and the rectus femoris helps with knee extension and hip flexion. By using the Impulse IF9308 machine with appropriate resistance settings, users can effectively strengthen and tone these muscles, improving overall lower limb strength, stability, and mobility.
