Wide vs Narrow
By keeping your feet close while doing leg presses, you can strengthen your outer quad muscles. If you think this muscle isn’t exactly what you should spend much time on, then you can move your feet further way apart and hit your inner quads.
Furthermore, it’ll greatly shock your adductor magnus. The more wider apart you position your feet, the better you’ll target inner quads and adductor magnus.
As you can see, there are plenty of ways to target different muscles just by performing one and the same exercise. If this isn’t enough, you can improve your workout by changing the amount of weight you use on this exercise as well as regulate your sets and reps range.
You can also make your leg training more rewarding by doing different types of squats.
