Try extending your knees from a seated position WITHOUT weight.

If your lower back still hurts when doing that, a visit to a sports doctor (or other qualified professional) is in order.

BTW - does your lower back hurt when you do other leg exercises (particularly the leg press?)

When you sit in the machine with your knees bent, is there a space between your butt and the seat back (back rest)?

Hopefully Matt and Stephen will see this as it's an old thread but I'm glad you cam back to it.

Make sure your hips are back firmly against the back pad when doing leg press and there should be a natural arch in your lower back. If not, adjust the seat position so you can do that. Lower the weight so you don't lift your hips during the press.

Make sure you follow up with a sports doctor as Stephen suggested.

I thought he was asking about knee extensions. Now i'm not sure.
