Dumbbell Bench To Barbell Calculator

A common issue for gym goers is determining where their strength should be when they switch between the barbell and dumbbell bench.

To make things easier, we developed a dumbbell bench to barbell calculator that should have you covered. Using our calculators, you can convert back and forth between dumbbell and barbell bench press.

How Did We Determine Our Dumbell Bench To Barbell Calculator Conversion Formula?

To determine our formula, we looked around for the average dumbbell bench to barbell bench ratio among gym users. We discovered that the average dumbbell bench-to-barbell ratio is around .363. Naturally, this is an average, so there will be some variance.

There were outliers as well, with some having a ratio as low as 0.24 and others as high as 0.45. Your ratio will be determined by your genetics and how much you train either lift.

How To Use The Dumbbell to Barbell Conversion Calculator

To use the Dumbell To Barbell conversion calculator, just type in your respective maxes for each of the lifts. If it is your dumbbell bench press, put in your max that you can do in terms of dumbbell per hand.

Why Is The Dumbbell Bench Press Harder?

A common mistake made by beginners in the gym is assuming that their dumbbell strength should equal their barbell strength. For example, you can see the logic behind assuming that a 200-pound barbell bench presser should be able to dumbbell bench press 100 pounds in each hand.

The issue without that line of thinking is that you are not taking into account instability. With dumbbells, your arms and the weight are not locked into position. This means that the stabilizer muscles in your chest and shoulders have to work harder to keep the weight stable. As a result, you simply cannot lift as much.

Another factor to consider is that heavy dumbbells can be difficult to get in the proper pressing position. Unlike a barbell, you cannot just simply unrack it. The process of pulling the weights off the floor and lowering yourself onto the bench can really drain your energy and strength causing you to lift less.

What Is A Good Dumbbell Bench Press?

Which Is Better? Dumbell vs Barbell Bench Press

Both of these exercises are staples in any workout program, so it is natural to compare them. Each of them has its own set of advantages and disadvantages. Overall, I would say that both exercises are found to be effective. If you are getting stronger on either lift, these are good signs that you are gaining muscle in your upper body. To see the best gains, I would recommend cycling back and forth between the two to avoid any stalls in progress.
