Try any or all of these ab moves individually or as an add-on to your existing workout. If you plan on doing all of them in a circuit, do one set of each move with 15 to 30 seconds between exercises, repeating the full circuit up to three times total.
Remember: Amazing abs begin in the kitchen, so it’s crucial to pair these moves with a healthy diet (and a good dose of fat-torching cardio).
Build better core strength in both your abs and lower back (in addition to your glutes and thighs) when you do the bird dog.
- Begin on your hands and knees with your hands under your shoulders and your knees under your hips.
- Engage your abs and extend your right leg behind you as your left arm extends by ear, palm facing down.
- Return to the start, keeping your torso as steady and still as possible during the entire exercise.
- Repeat with the opposite arm and leg.
Reps: 3 sets of 20 alternating reps (10 reps on each side)
2. Mountain Climber
Pump up the cardio while activating your abs with this multi-tasking, calorie-blasting move.

- As your right foot reaches back to the start, draw your left knee up.
- Continue alternating this way for the full set.
Reps: 3 sets of 20 alternating reps (10 on each leg)

A twist on the traditional crunch, the raised leg position in this move makes it impossible to cheat by using the glutes or legs, which can help deepen the contraction of the abdominal wall.
