Kettlebell Chaos: The 3 Most Unusual Kettlebell Abs Exercises You Need to Try

Kettlebells are an underutilised tool for core training, offering dynamic resistance that forces stabilisation and full-body engagement.

While most gym-goers stick to traditional planks and sit-ups, kettlebells introduce an element of chaos that stimulates the core in a unique way. Below, we explore three unusual kettlebell abs exercises that will challenge your core strength, stability and endurance, all backed by science.

Why Kettlebells Are Superior for Core Training

Kettlebells create an offset centre of mass, requiring constant micro-adjustments from the core muscles to maintain balance. This effect, known as reactive core stability, has been shown to improve functional strength and reduce injury risk (McGill et al., 2009). Studies have also demonstrated that kettlebell exercises recruit more muscle fibres than traditional static core movements, leading to greater activation of the rectus abdominis, obliques and transverse abdominis (Lake & Lauder, 2012).

1. Kettlebell Turkish Get-Up with Rotation

The Turkish Get-Up (TGU) is already a highly functional movement, but adding a controlled rotational component increases its effectiveness as a core-strengthening exercise.

How to Perform It:

• Lie flat on your back while holding a kettlebell in one hand with an extended arm.
• Press through your opposite hand to rise onto your elbow, then your hand.
• As you transition to a standing position, introduce a controlled rotation towards the side holding the kettlebell.
• Reverse the movement to return to the floor while maintaining control.

Why It Works:

Research by Fonseca et al. (2018) highlights the effectiveness of multi-plane movements for core stability. The rotational component further activates the obliques and enhances proprioception, improving coordination and spinal stability.

2. Kettlebell Hanging Windmill

This variation of the kettlebell windmill combines dynamic stability and eccentric core activation, making it an advanced movement for trunk control.

How to Perform It:

• Hold a kettlebell overhead with one arm fully extended.
• With feet shoulder-width apart, hinge at the hips while reaching your free hand towards the opposite ankle.
• Keep your gaze on the kettlebell as you descend, maintaining a tight core.
• Slowly return to a standing position without losing control of the kettlebell overhead.

Why It Works:

According to a study by Calatayud et al. (2017), overhead loading increases core muscle activation, particularly in the obliques and transverse abdominis. The eccentric nature of this movement also enhances anti-rotational core strength, which is critical for preventing spinal injuries.

3. Kettlebell Chaotic Dead Bug

The dead bug exercise is an established core stability movement, but incorporating a kettlebell adds an anti-extension and anti-rotation challenge that takes it to another level.

How to Perform It:

• Lie on your back with knees bent at 90 degrees and hold a kettlebell in both hands directly above your chest.
• Slowly extend one leg and the opposite arm while maintaining control of the kettlebell.
• Return to the starting position and repeat on the other side.
• To increase difficulty, loop a resistance band around the kettlebell and attach a small weight to create additional instability.

Why It Works:

Research by Hibbs et al. (2008) confirms that asymmetrical loading during core movements significantly increases deep core muscle recruitment. The instability created by the kettlebell forces the core muscles to stabilise against unpredictable movement, enhancing neuromuscular control.

Conclusion

These three unusual kettlebell abs exercises target the core in a functional, dynamic way that improves strength, stability and injury resilience.

By incorporating rotational, eccentric and chaotic elements, they offer superior core activation compared to traditional static exercises. The research supports their effectiveness, making them a must-try for those looking to elevate their core training.
