Everyone knows that we could probably all use just a little more exercise. Performing Leg Lifts is a great way to not only get more exercise, but also help develop the six pack abs you have always wanted!

[edit] Steps

Lie on the floor, legs straight out, hands at your sides.
Lift your legs straight up (not bending your knees at all) until they're at a ninety degree angle (or close).
Lower your legs and repeat without letting your legs touch the floor.

[edit] Tips

For more challenge there is equipment at most gyms that will allow you to raise yourself up using your arms as support and dangle your legs. You can perform leg lifts there too. If you're using this piece of equipment, you can make it easier by just raising your knees to your chest. It's more difficult to raise your legs to a horizontal position with your legs straight.
