There are several notable benefits of this ab exercise challenge besides getting a defined stomach. 

Builds Strong Core

Your abs are one of the most important muscle groups in your body.

Training them won’t just help you score a flatter tummy, but also make your core get stronger.

This is essential in more ways than you realize. 

The core is often thought of as just tone muscle or one area of the body. But in fact, it includes all the muscles in your mid-torso. From your lower back to side abs (obliques), deeper abdominals to the front six-pack ab muscles called rectus abdominis. 

Together, the core supports your spine and enables your body to functions and moves.

Speaking of bodily functions, think of the core as a pathway of any lower and upper body movements. 

According to Harvard, core muscles function as a central link in a chain connecting your upper and lower body (1).

Whether you are hitting a tennis ball or mopping the floor, the movement and necessary motions either originate in your core or move through it.

In short, they’re the foundation where almost all movements begin and passthrough. 

Training your abs is a way to allow your core to strengthen, your body to improve its mobility and movements. 

Yes, it is far more than just aesthetics. It impacts your daily life and almost everything you do.

Lose Belly Fat

Another benefit of having to go through a slew of ab workouts for a month is fat loss. Especially having to burn your belly fat, which is also known as visceral fat that causes harm to adjacent living organs.

How to Do This 30 Day Ab Challenge

To complete this challenge, perform the exercises below for the prescribed repetitions or hold time.

If you are a beginner, perform one set per day.

If you are looking for more challenges, perform 2-3 sets.

However, be advised that towards the end of the challenge, the workout itself becomes intense even just for one set. Pace yourself as you go. Try your best but also know your limits and stop if you need to.

You can always take this challenge again to keep breaking your own records!

1. Plank Exercise

The plank is a simple isometric core strengthening exercise that works the rectus abdominis, obliques, and the lower abs. It also engages your arms, back, shoulders and glutes, working full-body in just one exercise. 

Because it’s an isometric exercise, meaning you hold a position for a period of time, you won’t be doing it in reps. It’s simply a 30-second hold from the start to finish. 

To Perform the Plank:

  1. Lie face down on the ground with your legs extended back straight behind you. Keep your knees and feet together. Bend your elbows and keep your forearms on the ground or mat, facing each other. Support your weight on your forearms. 
  2. Contract your abdominals and prop your body off the ground. Fix your body alignment to form a straight line from your head to your heels. Hold it for 30-60 seconds as prescribed in the challenge. If it becomes harder to maintain the correct form, stop and rest. Continuing in the wrong form could cause back pain and more. 

Tips: If you’re a beginner, begin with the kneeling plank until you build enough core strength to perform the basic plank. One way to know if you are ready for this basic plan is to try to keep the plank position for 30 seconds straight. If you are capable of holding your body straight for that duration, go ahead and try this basic plank in this challenge. 

2. Side Plank

Side plank exercise targets and works the obliques, a.k.a Love handles or muffin tops. This exercise strengthens and tones obliques, abs as well as the lower back muscles that support your spine.

Side plank improves your core strength. That means you’ll have a better stable back that is less prone to lower back injuries.

Like the classic plank, this plank variation is also an isometric exercise. You keep the side plank position for the duration of time set in the challenge to complete this exercise. 

To Perform the Side Plank:

  1. Lie down on your right side with your legs straight out on the floor. Prop your upper body up on your right elbow and forearm.
  2. Contract your abs to raise your hips off the floor until your body forms a straight line from your ankles to the shoulders. Hold this position for the set duration of time. When one side is done, switch sides and repeat on your left side. 

Be sure to keep your abs and your buttocks engaged throughout. The plank works those muscles by having to contract them for a set time. 

Side plank too has a beginner-friendly version. It’s a kneeling side plank where your bottom knee may rest on the floor during the hold time to add support and stability.

3. Long Arm Crunch – V-Crunch

30-day ab challenge would not be complete with this new crunch variation.

While the classic crunch would keep your hands behind your ears, this exercise keeps your hands straight and extended. It’s sort of like sit-ups and crunches in one exercise. 

Longarm or V crunches bring an excellent challenge to your abs and core. They help to strengthen and tone the muscles in your abdomen by engaging your six-pack muscles, rectus abdominis, obliques, and the lower abs. Because it’s a bodyweight exercise, you can do it anywhere without needing any fitness tool. 

You may or may not be familiar with this crunch variation, but this new crunch is easy to learn and maximizes your efforts. 

To Perform the Lorn Arm Crunch:

  1. Lie faceup flat on your back on the floor with your legs extended back straight. 
  2. Bring your arms straight above your head and keep your body in a straight line from the hands to your feet. Contract your abs and in one movement, lift your torso and legs simultaneously and to try to reach your toes with your hands. This touch may or may not happen, but the point is to reach over to make an attempt. 
  3. Pause for 1-2 seconds and then lower your body back down to the starting position. Continue for the prescribed number of repetitions. 

If the ground is too hard for your back, be sure to use a yoga mat. It’ll give your back a softer place to land at each rep. 

4. Bicycle Crunch

The bicycle crunch is, in fact, the most effective ab exercise of all according to ACE experts (2). This floor ab workout effectively targets and works your rectus abdominis and obliques all at once. 

It’s also a fat-torching move that’ll burn crazy calories, crush fat, and tone your midsection. It’s one exercise that’s a must on this 30-day ab challenge. 

If you are a beginner at the start of your fitness endeavor, be sure to take it easy with this workout. This workout is a dynamic exercise that requires some basic fitness level and strength to perform correctly. 

Be sure to start by practicing the movements before you go full-throttle on this challenge. 

To Perform the Bicycle Crunch:

  1. Lie flat on the floor with your lower back pressed to the ground. Put your hands behind your head without locking your fingers. Bring your knees in towards your chest and lift your shoulder blades off the ground.
  2. Straighten your right leg out to about a 45-degree angle to the ground while turning your upper body to the left, bringing your right elbow towards the left knee. Make sure your rib cage is moving and not just your elbows.
  3. Now switch sides and do the same motion on the other side to complete one rep. Continue for the prescribed number of repetitions.

Last Words

Whether you are a beginner looking to start a fitness routine that’ll improve your fitness and tone up abs or an advanced exerciser wanting to lose the last inches of your stomach, this 30-day ab challenge can serve you greatly. 

It combines ab and core-focused isometric and dynamic moves that will not only target and torch the front part of your abs but also engage your entire core to improve the way your body functions. 

From plank to bicycle crunch, 30-day ab plan gives you no dull moment. It’s nothing but a good sweat session that’ll truly tackle your stubborn and problem area, the abdominals. 

Be sure to take note that ever 4th day is a rest day. This is purposefully put in to give your midsection the break it needs to properly recover from 3-straight days of hard work. 

In fitness, those rest days are just as important as the work itself, and your muscles’ building work takes place during those rest times. It’s essential that you get protein-rich, muscle-building meals to help the development of your lean muscles to start seeing defined abs. 

Lastly, every participant sees different results, and that’s normal and expected. As mentioned earlier in this post, various factors may influence your end results and progress. 

Before you start any new fitness regimen including this 30-day ab challenge, consult with a local specialist to make sure it’s right for you.
