28 Day Plank Challenge

Get ready to challenge yourself, this is it, you sign to start Planking every day. This challenge has been adapted from my exercise challenge for January, #PlankAwayJanuary. This 28 Day version means you can start it whenever you want and repeat it as much as you like. The challenge is FREE, however, I have a premium upgrade. This option allows you to track your challenge efforts, get daily push reminders on your mobile device and the ability to ‘Ask a Trainer’ any questions you have.

This challenge is staggered & progressively increases in time throughout the month with three levels to choose from and three plank variations, this challenge will be suitable for anyone of anyone as there are multiple ways to progress or regress the challenge. 

The plank is an excellent isometric exercise, it requires core stabilizers to fire to maintain body & spinal alignment.

Plank Test (perform before starting this challenge)

This challenge is progressive and you should notice some gains throughout the month. To start off you should test your current core strength with a Plank test. This simple test will give you an idea of where you are now, this can be compared when conducting the same test at the end of the challenge. The result of the test will help you choose the plank variation to do during the challenge.

To conduct the test:

  • Have a stopwatch ready or a friend with a stopwatch.
  • Get into the plank position.
  • Hold the plank for as long as you can.
  • Stop the test when you fail or you reach 2 minutes.

Choose the Plank variation based on your initial Plank Test result

  • Under 30 seconds – Choose the Beginner variation (Half Plank).
  • 30 seconds up to 1 minute 30 seconds – Choose the Regular or Alternative Plank variations.
  • 1 minute 30 seconds and above – Choose the Plank/Up-Down variation for a dynamic plank. Alternatively, you could use an unstable platform such as a BOSU, Balance Pod or Fitness Ball and place your feet upon them creating a more demanding static Plank exercise.

Test your progress with a follow-up Plank Test at the end of the month

After a month of regular planking, you should be feeling stronger with more endurance in your core and stabilizing muscles. To find out how you have improved, repeat the test you conducted at the start of the month. The test should be exactly the same conditions, same plank variation etc.

Required Equipment

Programme Design

I have designed this challenge as a progressive ascending pyramid, in simple turns, each day is equal or harder than the last. The challenge progresses at small steps enabling you to become stronger as you go through the month.

The challenge has two-day steps where we keep to the same target for two days (we can call this acclimatization if you like). It’s all to get you up to your target time at the end of the month, in a safe, effective and progressive manner.

Let’s do it! Pick your level below or Mix ‘n’ Match
