#1 Best Ab Workout

Show off a sexy core!

What makes this the best ab workout is that it strengthens all the muscles in your core, while burning unwanted fat. That’s right, this calorie-torching ab workout doubles as cardio.

The workout begins with burpees and mountain climbers, which are great for raising your heart rate. Once you’ve started sweating, you begin working hard to tone and strengthen all the muscles in your middle. Russian twists target your obliques, the muscles running along the side of your torso. Jackknife crunches target both your upper and lower abs. The reverse crunch puts the focus on strong lower abs, and finally, holding the plank position will engage muscles along your entire body.

If you want to take the workout to the next level, try using a light dumbbell (2-8 lbs.) for your Russian twists and jackknife crunches.

Overall, you’ll be amazed at what the best ab workout can do for your core!

What You’ll Need: a gym timer, a mat, and (optional) a light dumbbell.

What to Do: Set your timer for 7 minutes. Cycle through the exercises in order without break. Rest for 1-2 minutes and repeat.

  2. Hello my name is Camilia and I struggle with finding a workout I trust How many times should we repeat the exercise in a day?and should I pair this exercise with glute’s and arms everyday or should I do the them separately.

    1. Camilia, I only recommend doing this workout once per day. Performing the workout 3 x’s weekly on, for example, Monday, Wednesday, and Friday, works great.
