Barbell vs Dumbbell Shoulder Press For Fighters

Both barbells and dumbbells have their place in a fighters program for exercises like the shoulder press… Either to target specific qualities in different blocks of training, to accommodate shoulder mobility or injury, or simply because of the limited availability of one or the other in your gym!

In this video all is explained, while I share part of a discussion from a video call with one of my Heavy Hitter clients… He struggled to get hold of two barbells for the Deadlift and Shoulder Press superset pairing in his program.

Armed with the information shared on this call, he opted to use a barbell for the Deadlift, and then use a pair of dumbbells for the Shoulder Press – so he could compact his training session as much as possible without negatively affecting his results.

Video Summary

Choosing Between Barbell and Dumbbell Shoulder Press

When deciding between the barbell and dumbbell shoulder press, you must consider stability and load management. With a barbell, your hands are fixed in place, providing more stability which allows you to lift heavier weights. For instance, if you can shoulder press 100 kilograms with a barbell, you might use about 80 kilograms combined (40 kilograms per hand) with dumbbells – the total load using dumbbells is typically about 80% of your barbell lift. This discrepancy arises because dumbbells require more stabilizing effort, which can reduce the maximum load you can handle.

Why Dumbbells Challenge Stability

Dumbbells introduce an element of instability compared to a barbell. This means that while you may lift less weight overall with dumbbells, the exercise forces your stabilizing muscles to work harder. This can be particularly beneficial in the later stages in your training phase, closer to a fight. In Muay Thai, where you frequently deal with uneven and unstable positions, incorporating dumbbells into your routine can mirror these demands, enhancing your sport-specific strength.

Progressive Training Approach

I often use dumbbells in a progressive manner throughout training blocks. Starting with barbells for initial strength and stability, and gradually shifting to dumbbells as the training phase progresses, aligns well with the unpredictable nature of Muay Thai. By beginning with a stable base and then increasing instability, you build foundational strength before adapting to the sport’s dynamic demands.

Mobility and Injury Considerations

Dumbbells also offer an advantage when it comes to shoulder mobility. If you have a shoulder injury or limited mobility, dumbbells allow for a more individualized range of motion. You can adjust your grip and position to find a comfortable angle (typically in a neutral grip – thumbs pointing toward your shoulder), which may help avoid pain that can occur with a barbell.

Final Thoughts and Recommendations

Ultimately, the choice between barbell and dumbbell shoulder presses should align with your training goals and physical condition. If stability and heavy lifting are your priorities, the barbell press is your best bet. However, if you’re aiming for sport-specific strength and shoulder mobility, or are dealing with a shoulder injury, incorporating dumbbells into your regimen will serve you well. Experiment with both approaches to find what works best for you and enhance your overall performance in Muay Thai.

Actionable Advice

Incorporate both barbell and dumbbell shoulder presses into your training routine. Start with barbell presses to build foundational strength and gradually incorporate dumbbells to challenge your stability and mimic the dynamic nature of Muay Thai. Adjust your training based on your injury status and mobility goals, and always listen to your body to avoid unnecessary strain.
