Looking to get in an effective ab workout at home? Great news: if you don't belong to a gym or have access to workout equipment, at-home bodyweight workouts can be just as challenging. And that's especially true when it comes to working your abs. For an amazing core burn, all you need are a mat (or a comfortable floor), your own bodyweight, and the right moves — and you know we've got you covered with that last one. Keep reading for 15 easy ab exercises that are simple to learn but actually really challenging (and super effective).

Choose three to five of these bodyweight ab exercises to create your own at-home ab workout. Mix them up so you work different parts of your core, including your lower abs, upper abs, obliques (the sides of your abdomen), and transverse abdominis (your deep abdominal muscles). You'll see classic moves like plank variations, reverse crunches, bicycle crunches, Russian twists, and Pilates-inspired moves (such as double leg lifts and the Pilates swimming move that targets your back muscles — which are also part of your core!). If you need some guidance on how to put these easy ab exercises together into a routine, try this quick bodyweight ab workout that uses six of the moves listed here.

Easy Ab Exercise: V-Sit

Test out your balance and build a strong core with V-sits.

  • Lie on your back, and reach your arms rigidly to your side, off the floor. Lift your legs off the floor, so they're at about a 45-degree angle. Lift your head so your shoulders are off the floor as well.
  • When you're ready to begin, lift your upper torso off the floor and bend your knees. You can lean back to make this move harder or come up more to make it easier.
  • Slowly lower your upper body back down to the floor, straightening out your legs as you do so. Stop when your back is on the floor, but not your head, shoulders, or legs. That's one rep.

Easy Ab Exercise: Resistance Band Flutter Kicks

No-equipment flutter kicks will ignite your abs. If you have a resistance band to add, you'll feel it even more!

  • If you have a resistance band, loop one handle of the band on either foot. Hold onto the middle of the tube with both hands.
  • Lie on your back. Draw your navel toward your spine, and press your low spine into the floor to protect your lower back. Lift both legs up so they are almost pointing straight up toward the ceiling.
  • Scissor your legs up and down one at a time, starting with the left leg. Move slowly, and point your toes. Each time your right foot lowers down, it counts as one rep.
  • To make this move more difficult, lower your legs so they are about six to 10 inches above the floor, as in the lower image. Make sure to keep your abs scooped when you work with your legs close to the ground.
