Triceps extensions are great for your arms as well, but with this exercise, you're also helping your biceps.

What you want to do is sit down, keeping your head, your neck, and your spine straight.

You'll need one of your weights for this one too, because you'll be lifting your arms over your head, so that your palms face inward, allowing you to clasp your fingers over it.

Using just the muscles in your upper arms, you need to lower your weight down so it's behind your head, then hold it before going back up so your elbows are straight.
