28 Day Abs Challenge (Female)

28 Day Abs Chalenge

Get ready to work those abs, this challenge has been adapted from my monthly challenge for April (AprilAbs), this challenge has two exercises each day, one to target the upper abdominals and one to target the lower abdominals. All you need is a few minutes each day and a little motivation, we will get you into the habit of doing a little exercise every day. The challenge is progressive and really very simple, just going up by one rep each day. The two exercises will only take a little time to complete. Our challenges are designed to keep you active and working, NOT to provide ridiculously hard workouts, participation is what’s important.

Each exercise has progressive variations to suit your fitness and ability level.

This exercise challenge will work your abdominal muscles every day, building strength and stamina and improving your core stability. The abdominals have an essential role in everyday life should not be understated; they help support your trunk, protect your lower back and enable you to go about your day. A sound core will ensure you can perform at your best, prevent injury and will allow you to do manual tasks without fatigue.

April Abs Exercise Challenge

Equipment Needed

Test your progress

To test how we get on throughout the month and how well you’ve progressed, it’s a good idea to perform a simple sit-up test. It would be helpful to recruit a friend or loved one to help you time your effort and keep count. All you need to do is set a timer to one minute and perform as many repetitions of a full sit-up exercise as you can within the minute.

Warning: If you feel pain during the test or are unable to continue, stop and record the number you achieved.

Repeat the test at the end of the month to check how much progress you have made.

Scoring the Challenge

The challenge is split into 3 levels for which you can score your progress, you don’t need to keep to one level, You can mix & match and go up or down a level. Each level has a score associated with it, use the free-scoring sheet available for download below to track your progress and tally your total score for the month

You get either one, two or three points for the target level and either one, two or three points for the exercise variation. A maximum of ‘6’ per day and a minimum of ‘2’, unless you skip a day in which case it would be ‘0’.
