Build those inner thighs with constant cable tension.
Move from the hip, not by leaning your torso. Keep your upper body still.
With a cuff on your inside ankle and the cable pulling your leg away, every rep of sweeping the leg across your body is your adductors working against smooth, constant tension, one side at a time. The standing setup also makes your planted leg's hip work overtime to keep you level, a bonus the seated machine never offers. It earns its place because strong inner thighs stabilise your squats and lunges and get almost zero direct work anywhere else.
The machine is easier to load heavy, the cable version trains one leg at a time through a longer, more natural sweep while you balance. If your adductors are weak or uneven, the cable exposes and fixes it faster.
You're standing on one leg while a cable drags the other sideways, wobble is part of the deal. Hold the frame lightly for balance, slow the reps down, and it steadies within a few sessions.
They stabilise your knee and pelvis in every squat, lunge, and change of direction, and adductor strains are one of the most common gym and sport injuries. A little direct work is cheap protection.
