There are only two types of people: those who love abdominal workouts and those that avoid them like strongmen avoid cardio. Nevertheless, everyone agrees that unless you’ve won the genetic lottery, you won’t achieve a toned abdomen without regular exercise. An effective way to achieve this is through a well-designed circuit training. Today’s circuit training features effective exercises that both beginners and advanced athletes can incorporate into their routine.
Circuit training is a type of workout where you move from one exercise to another until you complete the entire set. Between individual exercises, there are usually short rest periods or none at all. It’s truly an intense workout that saves you time. Another advantage of circuit training is that you don’t need any equipment for it, making it manageable at home or anywhere else. If you want to make it more challenging, you can try harder variations with added weights, which are also listed for each exercise. Therefore, anyone who is looking to strengthen and sculpt their abs can incorporate this into their training plan.
How to Do the Ab Circuit?
In this circuit training, you will find exercises targeting the rectus abdominis, oblique abdominals, lower abdominals, and also the core muscles. This will help you work on developing your six-pack as well as the deep muscles, which are important for maintaining body stability during every movement.
You can incorporate the ab circuit either on its own or add it to another muscle group session. For visible results, aim to do it 2–3 times a week. Gradually increase the number of repetitions, and increase intensity by shortening the rest periods between exercises. Once you are comfortable with the basic version, you can switch to more challenging variations using equipment. [1–2]

6 Exercises for the Ab Circuit
For this circuit training, you only need a mat and enough space around you. Before the workout, make sure to warm up lightly with activities like jogging in place or skipping rope. At the end, as part of the cooldown routine, you can add a short stretching.
1. Tuck Ups
- Starting Position: Lie on your back with your arms extended overhead. Keep your legs straight and lift them a few centimetres off the ground.
- Execution: Exhale as you engage your abdominal muscles to lift your head and entire torso off the mat. Simultaneously, bend your legs and bring your knees towards your chest. Reach with your hands towards your feet. Then, inhale as you return to the starting position and repeat the exercise.
- Common Mistakes: Limited range of motion, arching the back.
- How to Make the Exercise More Challenging? Place a dumbbell between your feet or hold one in your hands, or attach ankle weights to increase resistance.

2. Bicycle Crunch
- Starting Position: Lie on your back and lift your straight legs a few centimetres off the ground. Lightly touch the sides of your head with your fingertips and keep your elbows open.
- Execution: Activate your abdominal muscles and bring your left knee towards your right elbow, then immediately bring your right knee towards your left elbow. Continue this dynamic alternating motion of bringing your lower limbs towards your elbows. Focus on your breathing during the exercise and be mindful not to lift the lower part of your back off the mat.
- Common Mistakes: Excessively pressing the hands into the head, limited range of motion, insufficient activation of abdominal muscles, arching the lower back.
- How to Make the Exercise More Challenging? Use ankle weights or place a resistance band around your feet. Perform the exercise in the same manner as the basic version.

3. Heel Taps
- Starting Position: Lie on your back with your head on the mat and arms alongside your body. Bend your knees slightly and lift them upwards.
- Execution: Exhale as you smoothly lower one leg towards the mat, lightly touching it with the heel, then inhale as you bring it back up. Repeat with the other leg. To decrease the difficulty of the exercise, bend your knees more.
- Common Mistakes: Limited range of motion, insufficient activation of abdominal muscles, arching the lower back.
- How to Make the Exercise More Challenging? Place a resistance band with lighter resistance around your feet, or lower both legs simultaneously towards the mat instead of one at a time.

4. Elbow to Knee Crunch
- Starting Position: Lie on your back with your arms alongside your body and lift your straight legs a few centimetres off the ground.
- Execution: Exhale as you engage your abdominal muscles to bend your knees and bring them towards your head. Then, lift your pelvis a few centimetres off the ground. Inhale as you return to the starting position and repeat the exercise.
- Common Mistakes: Uncontrolled movement, insufficient activation of abdominal muscles, arching the lower back.
- How to Make the Exercise More Challenging? Hold a small dumbbell with your feet and perform the exercise in the same manner.

5. Mountain Climber
- Starting Position: Kneel on the ground and transition into a plank position with arms extended. Place your palms, fingers spread, under your shoulders but slightly wider than shoulder-width apart. Your shoulders should be pulled away from your ears and your shoulder blades squeezed together. Activate your core and strive to maintain a straight body line. Avoid arching your back, especially in the lumbar region.
- Execution: Exhale as you bend one knee and pull it towards the elbow of your extended arm. Then, return the leg to the starting position and immediately repeat on the other side. Breathe smoothly and dynamically alternate the motion of bringing your knees towards your elbows.
- Common Mistakes: Arching the back, hips sinking towards the ground, excessively lifting the pelvis upwards, insufficient range of motion.
- How to Make the Exercise More Challenging? Support your hands on a half-ball (inflated side up), an exercise ball, or a slam ball. You can also use a weighted vest.

6. Plank Shoulder Taps
- Starting Position: Kneel on the ground and transition into a plank position with arms extended.
- Execution: Exhale as you lift one hand and touch the opposite shoulder with your palm. Then, inhale as you return to the starting position, and repeat the same movement with the other hand. Continue this sequence until you complete a total of 8-16 repetitions.
- Common Mistakes: Arching the back, hips sinking towards the ground, excessively lifting the pelvis upwards.
- How to Make the Exercise More Challenging? Support your hands on a half-ball (inflated side up). You can also simultaneously lift the opposite leg a few centimetres off the ground.
