Dumbbell Vs Barbell Bench Press – Which is Better?
A frequently asked question when it comes to chest training is ‘Are Dumbells better or worse than a Barbell?’ – There is no yes or no answer to this one, it is entirely dependant on your goals.
As you can load a barbell gradually with minor increases in weight, they are the ideal tool for building strength. To get stronger you need to progressively lift more weight over a period of time. If you can’t, something is not right – You can perform all the drop-sets/supersets/giant sets/forced reps etc etc, but if the weight is not increasing, you will not get stronger – You will plateau much quicker with Dumbbells due to the large increase in weight percentage between them. Even a well stocked gym will have the weight increases around the 2.5kg mark. This is as increase of 5kg on your lift which is going to be a challenge for most and makes progressive loading nigh impossible. If your goal is pure strength you can load significantly more onto a barbell due to its balance and stability and so is the perfect tool in this situation.
Muscular imbalance is another thing to address. Although you can try and be more aware of pushing equally or focusing on leading with the weaker side, with a Barbell imbalances can be masked. When using Dumbbells you will be much more aware of imbalances as one side will be unstable or will fatigue first, and will prevent your dominant side from growing faster than the other. Balanced body strength leads to greater performance and lowers the chance of injury.
The Barbell bench press is also harder on your joints than dumbbells. When pressing with dumbbells, your hands won’t remain completely pronated (palms forward), but will rotate slightly inwards reducing the stress on your wrists elbows and shoulders (particularly rotator cuff) and therefore reducing your chance of injury.
With regard to muscle recruitment, researchers noted that electrical activity or muscle stimulation in the arms was greatest in the triceps with a barbell, but when dumbbells are used the biceps also come into play as stabilisers. The Barbell activates more upper chest fibres and anterior deltoid due to the wide grip in the top position, however as your hands are free to move across your body with dumbbell presses there is greater lower pectoral activation. Although yes, you will use more stabilising muscles with the dumbbells, you will be limited by the weight increases as previously mentioned meaning you will plateau sooner.
In my opinion the barbell is the better option as you can handle a lot more weight doing the same exercises. More weight moved = bigger muscles. This doesn’t mean you shouldn’t use dumbbells, you should try and use both – Just keep the main focus on increasing the weight on the bar and use dumbbell sets to ensure you work the entire chest area, prevent imbalances and keep your joints healthy.
