The 3 Best Kettlebell Exercises to Build Upper Body Mass

Kettlebells are a versatile tool for building upper body mass, offering unique benefits that barbells and dumbbells often cannot replicate.

Their offset centre of gravity creates additional challenges for stability and control, engaging multiple muscle groups with every movement. In this article, we’ll explore three of the best kettlebell exercises for building significant upper body mass, all supported by scientific evidence.

The Benefits of Using Kettlebells for Upper Body Training

Kettlebells are exceptional for functional strength and hypertrophy. Research shows that kettlebell training improves muscle activation due to its emphasis on grip strength, stabilisation, and dynamic movement (Manocchia et al., 2013). Unlike traditional free weights, kettlebells often require greater coordination and stabiliser muscle engagement, particularly in the shoulders, core, and arms.

This translates into superior muscle development and functional strength that can be applied to sports and everyday activities.

Kettlebells and Muscle Hypertrophy

While kettlebells are often associated with conditioning, they are highly effective for hypertrophy when used with appropriate weight and volume. A 2018 study by Jay et al. demonstrated that heavy kettlebell lifts like presses and pulls stimulate significant muscle fibre recruitment in the upper body, enhancing growth potential when integrated into strength-training routines.

1. Kettlebell Military Press

The kettlebell military press is a foundational movement for building massive shoulders, triceps, and upper chest. The exercise focuses on vertical pressing strength, with the added benefit of stabilising the core and shoulder girdle due to the kettlebell’s unique weight distribution.

How to Perform the Kettlebell Military Press

1. Start by holding a kettlebell in the racked position with the bell resting on the outside of your forearm.
2. Keep your wrist straight and engage your lats for stability.
3. Press the kettlebell overhead in a straight line while maintaining a tight core and neutral spine.
4. Lower the kettlebell slowly to the racked position.

Why It Works

The kettlebell military press is superior for building upper body strength and mass because it challenges the deltoids, triceps, and core simultaneously. According to a 2017 study published in the Journal of Strength and Conditioning Research, overhead pressing with a kettlebell enhances stabiliser muscle activation compared to a barbell press due to the dynamic movement of the bell (McGill et al., 2017).

Tips for Maximum Hypertrophy

• Use a heavy kettlebell that allows 6–8 reps per set with proper form.
• Incorporate tempo training by taking 2–3 seconds to lower the weight.
• Alternate arms to focus on each shoulder individually and prevent strength imbalances.

2. Kettlebell Renegade Row

The kettlebell renegade row combines pulling strength with core stability, making it one of the most effective compound exercises for upper body mass. It primarily targets the lats, traps, and rhomboids, while also engaging the biceps and forearms.

How to Perform the Kettlebell Renegade Row

1. Place two kettlebells on the ground shoulder-width apart and assume a high plank position with hands gripping the handles.
2. Keep your core tight and your hips level as you row one kettlebell to your side, retracting your shoulder blade.
3. Lower the kettlebell with control and repeat on the other side.

Why It Works

Renegade rows are exceptional for building back strength and mass while improving core stability. The unilateral nature of the movement prevents muscle imbalances and ensures symmetrical development. A study by Schoenfeld et al. (2010) highlights the importance of compound pulling exercises like rows for maximising hypertrophy in the back muscles.

Tips for Maximum Hypertrophy

• Keep your body rigid throughout the movement to minimise momentum.
• Use heavier kettlebells as your form improves, aiming for 8–10 reps per set.
• Perform slow, controlled reps to increase time under tension, which is critical for muscle growth.

3. Kettlebell Floor Press

The kettlebell floor press is an excellent alternative to traditional bench pressing, targeting the pectorals, triceps, and anterior deltoids. The kettlebell’s instability forces the stabilising muscles in your shoulders to work harder, enhancing both strength and hypertrophy.

How to Perform the Kettlebell Floor Press

1. Lie on your back with a kettlebell in each hand, elbows bent and resting on the floor.
2. Press the kettlebells upward until your arms are fully extended, keeping your wrists neutral.
3. Lower the kettlebells back to the floor with control.

Why It Works

The floor press reduces strain on the shoulder joints while allowing for maximum activation of the chest and triceps. Research by Barnett et al. (2015) found that kettlebell pressing exercises improve neuromuscular activation in the chest and shoulders, making them ideal for hypertrophy.

Tips for Maximum Hypertrophy

• Use a weight that challenges you within 8–12 reps.
• Focus on a slow eccentric phase to increase muscle activation.
• Perform supersets with push-ups or dips for added volume.

Programming for Upper Body Mass with Kettlebells

To maximise muscle growth, integrate these exercises into a well-structured training programme. Aim for 3–4 sets of each exercise, using a rep range of 6–12 depending on your goals. Pair kettlebell exercises with compound lifts like pull-ups and dips to create a comprehensive upper body workout.

Progressive Overload

Progressive overload is essential for building upper body mass. Gradually increase the weight of your kettlebells or the number of repetitions to stimulate continuous muscle growth. Ensure adequate recovery between sessions to allow muscle repair and adaptation.

Rest and Recovery

Kettlebell training is intense and places high demands on your nervous system. Allow at least 48 hours of recovery between upper body sessions and prioritise sleep, nutrition, and hydration to optimise results.

Conclusion

Kettlebells are an underrated tool for building upper body mass, offering unique advantages in stability, coordination, and muscle activation. The kettlebell military press, renegade row, and floor press are three of the best exercises for hypertrophy, targeting major muscle groups while enhancing functional strength.

Incorporate these movements into your training programme with progressive overload and proper recovery to achieve substantial gains.
