When it comes to bodyweight exercises, the abdominal muscles are often targeted for training. You don’t need sophisticated equipment to train the abs; bodyweight movements alone can build muscle and strength. However, just like with other muscle groups, specific workouts may stimulate the muscles better than others.
In a study comparing 13 common abdominal exercises1, the American Council on Exercise (ACE) identified three ab workouts that stood out from the rest: bicycle crunches, captain’s chair crunches, and crunches performed on an exercise ball. These three core workouts targeted muscle stimulation in the rectus abdominis and obliques.
These core exercises should not only strengthen your abdominal muscles, but they should benefit you in other ways too. Strong abdominals2 are crucial for injury prevention, good posture, athletic performance, and staving off lower back pain.

To try and maximize your ab workout, knowing which muscles make up the abs3 is useful. While some exercises primarily stimulate the rectus abdominis (the front ab muscles), others call the obliques (internal and external) or the transverse abdominis into action. The external obliques are the muscles located on the sides of the rectus abdominis around the waist, whereas the internal obliques are positioned just below the rectus abdominis. The transverse abdominis is an internal stabilizer located on the lateral sides of the abdominal wall.
Next time you want to train your abs, incorporate the first three core exercises mentioned below into your workout regimen. The only piece of equipment you’ll need is an exercise ball, which you can find at retail or specialty sports stores. You’ll leverage the power of bodyweight to help build your abdominals! Let’s walk through each of these movements step by step.
Since this ab exercise utilizes all of your abdominal muscles, ACE highlighted that bicycle crunches are fundamental for ab training. They help stimulate your abdominal muscles so you feel that burn and help improve your fitness.

This core exercise4 requires a captain’s chair, a seatless chair with a back and armrests. Don’t be surprised when your obliques feel taxed after these crunches!
Ranked the third most effective abdominal workout5, crunches performed on an exercise ball do a much better job of engaging your core than floor crunches. This exercise targets the abdominals and oblique muscles precisely.
While the above ab exercises are highlighted by ACE, many others effectively engage your core! When paired with bicycle crunches, captain’s chair crunches, or exercise ball crunches, the following core exercises can offer the variety you need to keep your ab training interesting.
As a total-body movement, V-ups are incredibly powerful and challenging to master! In this core bodyweight exercise, you’re creating a “V” with your upper body and legs, engaging your core during the process.

Great for all of your abdominal muscles, deadbugs are a functional warmup for lower body workouts, but may also be incorporated as part of your core workout. The key to this movement is to keep your lower back flat on the floor.
A plank is a bread-and-butter movement for abs workouts. With bodyweight alone, planks6 are challenging, even to the most advanced fitness enthusiasts.
Side planks7 are a great addition to traditional planks, as they help strengthen the shoulders, hips, and obliques. Since you’re on your side in this core exercise, the obliques are doing some heavy lifting here.

If you’re looking for core exercises that integrate your hip flexors, heel taps are a worthwhile addition to your ab routine. Once you get going with these, you’ll feel your obliques working hard!
If you don’t have access to a captain’s chair, reverse crunches provide a similar movement. Instead of hanging, you’ll lie on your back without placing strain on your back or neck.
When performed correctly, hollow holds will strengthen your abs. The contraction of your ab muscles is part of what powers this movement, so it’s important to first nail the form down on these, as is the case with the other exercises.
When paired with a healthy diet, these ab exercises can help you build stronger abdominal muscles. As you work on your core, you’ll better understand which muscles you’re utilizing in these movements. Plus, our iFIT Trainers are here to help you strengthen your core!
The above ab exercises are ideal for a challenging home workout. Although they only require your bodyweight, you’ll find that they offer a range of physical and mental benefits. Depending on which exercises you choose to do, you can easily knock out a 10 minute ab workout in the morning, on your lunch break, or in the evening after work. Once you’re ready to take your ab training to the next level, your iFIT Trainers will be waiting for you!
