I’m super excited about this flat stomach fat burning ab workout routine. It’s quick. It’s fun. It works.

Once upon a time, all I ever wanted was a flat stomach.

10 years ago I was 40 pounds heavier than I am today.  I used to hate the way my stomach fat would budge out over the top of my pants.  I used to have to pull my pants way up or hide my stomach behind loose tops and dresses. It was NOT fun feeling bloated, flabby, and insecure in jeans and tight dresses.

All I ever wanted was Britany Spears abs… after all Brittany Spears was the queen of crop tops at that time.  I wanted to be a confident crop top queen, too!

This was the goal…  Tight, flat, stomach to-go please!  Throw in that outfit, too!

But this was before I was a trainer and nutritionist… and didn’t know how to transform my body yet.

I used to do a million crunches to try to melt my stomach fat off.  But I never really saw definition pop or my stomach get flat. (SO frustrating!)



If you want a tight, flat stomach, crunches should be a small part of your ab workout routine.

Crunches are just one of many, many ab exercises you can use to get a tighter, flat stomach.

It wasn’t until I started switching up my ab workouts and adding in new core exercises and proper nutrition that I was able to see my definition pop through.

Woo! These photos were taken 10 approx. years apart.  My after photo was after my car accident that injured my spine… and I still didn’t lose my definition.  And I only train my abs once a week.

Why I am I telling you this?  Because I want to let you know that tight, flat abs are possible for you, too.

So many of my clients rely on crunches to get flat abs like I used to… but they’re not getting results as quickly as they want.  

That’s why I put this flat stomach ab workout together for you.


Fat Burning Flat Stomach Ab Workout


  • We’ll be using 6 different ab exercises that target the abs in different ways.  Rotating between the different exercises will help engage more core muscles so you can get flat abs and burn more fat during the workout.
  • This ab workout routine only takes about 20 minutes.
  • To get started, do each exercise until you feel the burn.  Once you feel the burn, do 5 more and stop.  You can add more reps as your core gets stronger.  Ideally, you’ll be doing each exercise at least 15 times.
  • Quickly move from one exercise to the next, taking little to no rest between the moves.
  • Completing one full round of all 6 exercises – counts as one set.
  • Do 3 full sets to complete the workout. You can add another set, too if you want. 🙂
  • Try to train your abs 1 to 2 times a week.  I recommend using this workout along with this belly fat burning ab workout for women.
  • To burn the most belly fat, also use a fat burning meal plan & complete training routine.

Stand with your feet apart. While holding a weight with both hands, lift the weight up and across to one side. Your feet should pivot to help you extend the weight back and to the side. This is your start position. Pivot your feet as you rotate the weight down and across your body toward the opposite corner. Reverse the movement, lifting the weight back up and back across your body to the start position. One full ‘chopping’ movement counts as one rep. Do the same number of reps on the other side to complete your set.

If you liked this workout you’ll love my other ab workouts too!

P.S.  You can’t out-exercise too much food or a nutritionally bankrupt diet.  Abs really are made in the Kitchen and we can burn fat faster with a fork than we can workouts…  Keep that in mind if you don’t like exercise.

P.P.S. If you love food and you want rapid results my Total Transformation program is for you!  It has workouts too BUT the meal plan portion of this program will totally transform your metabolism on the inside so you get healthy, happy, and fit on the outside.
