Discover the secrets to uncovering toned & defined abs in time for Summer!
One of the truest phrases in the fitness world is, “If it doesn’t challenge you, it won’t change you.” We took that to heart when we created this 7-day Summer abs challenge! It’s not going to be easy, but it will definitely be worth it.
For the next 7 days you will be asked to perform specifically designed workouts that will target your midsection from every angle. You see, your core is made up of multiple layers of muscle that all must be trained equally. It takes a lot more than crunches to create toned and defined abs, and we’ve got you covered! If you want strong and sexy abs, this challenge will help you achieve them!
Want Even Greater Results?
Before we get started on the challenge, we want to share a few bonus tips for success. There are several additional ways to uncover those muscles and get gorgeous-looking abs that have nothing to do with exercise. A proper diet is just as important as a consistent workout routine:
1. Drink water throughout the day and always have some on hand when doing this challenge. Staying hydrated is crucial to success.

2. Eat smaller portions to help decrease overall caloric intake.
3. Eliminate refined sugar and grains. Instead, eat whole foods that don’t have added sugar.
4. Avoid sodas – diet included. Instead, try these healthy beverage options.
5. Consider eating more often, 5-6 times each day. Remember, meals should not be standard restaurant portions but rather mini meals. Eating on salad plates instead of dinner-sized plates is a good start.
6. Eat breakfast and you’re more likely to stick to smaller portions throughout the day. Try these incredibly simple breakfast options.
7. After this challenge has ended, be sure to continue doing ab workouts at least three times weekly.

Hi, I’m a 13 year old girl and I’m trying to get a six pack before school starts. Do you have any helpful tips for me.
Alexa, Our site’s workouts are created specifically for adults.
Ok, but can you at least give me some helpful tips. I mean I work out really hard like an adult and I already have a two-pack.
Alexa, Before starting any exercise program, be sure to discuss first with your parents and family doctor. They will likely help
you decide what program is best for you. Thanks! 🙂
Hi!
Could you please suggest a move to replace the side v-ups?
Thanks 🙂
Sure! The good old bicycle is great for obliques. You can watch the video here https://skinnyms.com/5-best-moves-get-rid-side-fat/
Starting this challenge today! I could really use a workout that’ll tone my body! Can’t wait for results!
Hey Elizabethe!
Fantastic! You’ve got this! Be sure to let us know how it goes, and remember to check out all of our other Fitness Challenges, afterwards. 🙂
Hi Elizabethe, This is a very popular workout. Enjoy and keep us posted. 🙂
This had been my go to ab workout back when I was regularly working out. I had the page bookmarked and recently started going back to the gym so came back to this page and saw it had been updated in 2020. 🙁 Is there any way to find the original ab worked posted in 2014??? I remember it gave me a core burn like nothing else!
I highly recommend our 7-Day Ab Challenge. Maybe this is the one you’re remembering.
