Same machine, three totally different workouts 👀
Where you put your feet decides what works hardest:
1️⃣ Feet close + low → quads take over
2️⃣ Feet wide + turned out → hello, inner thighs
3️⃣ Feet close + high → hamstrings + glutes do the work
Small change, big difference. Try it on your next leg day.
