You may have your long term fitness goals, you may be waiting for the gyms to open, you might not have anything planned but have every intention of doing so. There’s no better time to start than today. 

 30 days is nothing in the grand scale and between day 1 and day 30 of this fitness challenge, your progression and differences will be noticeable both physically and in your appearance.   

 Complete this challenge to get you motivated for your longer-term goal, your feel-good factor and a great sense of achievement. 

What are the benefits? 

This challenge will target every muscle in your core and as the workouts get harder, bring in other muscles in the body that support your core strength.  Over the 30 days, the intensity will increase, exercises will get harder and your core strength, general fitness and visible appearance will only get better.

How to do the 30-Day ab challenge

All these exercises are bodyweight only meaning no time wasted setting up equipment and minimal space needed.  Regardless of your level of training, this can be achieved by anyone from beginner to advanced trainers.

The 30-Day Ab Challenge 

Each workout will progressively get harder and down the line, introduce more difficult exercises to allow you to keep pushing the boundaries.  Don’t skip rest days, they're important for your recovery.

Complete each day to the best of your ability and if you need to split the exercises into manageable reps then that is fine, just hit a minimum of ten and keep the rest periods short.
