Ready to scorch your core? We asked Women's Health's Next Fitness Star Selena Watkins for 17 no-equipment abs moves you can bust out even if you're miles from the gym. 

From "sexy jacknives" to "bear hugs," these moves will challenge your muscles while also ensuring you're never bored with your core work. (Get more fat-torching moves with Women's Health's All in 18 DVD!)  

Remember to keep your abs muscles engaged throughout each and every movement—and don't forget to breathe. Six-pack abs, here you come. 

Special thanks to Life Time Athletic at Sky for letting us sculpt six-pack abs in their space.
