💡Tips
Adjustable dumbbells can be challenging to load due to the total weight of an adjustable dumbbell being more then the weight of the weight plates that comes with the adjustable dumbbell. The adjustable dumbbell contains the weight plates, collars, and handles. Each of these component adds to the total weight of the adjustable dumbbell.
If you fail to account for the weight of the handles and the weight of the collars, you could end up with one adjustable dumbbell that weigh more than the other adjustable dumbbell. To avoid this problem, you should first determine the weight of the handles and the collars that comes with the adjustable dumbbell set. Many people will attempt to guess the total weight that the adjustable dumbbell set will have.
How to Calculate Adjustable Dumbbell Weight
However, guessing at the total weight of the adjustable dumbbell set are not accurate due to the varying base weight of the handles. To determine the total weight of the adjustable dumbbell set, you should use a calculator. The calculator will include the weights of the handles and the collars when calculating the total weight that the adjustable dumbbells can have.
Using the calculator, you can input the weight of the handles, the weight of the collars, and the weight of the plates that you have available. The calculator will then show you the total weight that you can load onto the adjustable dumbbells. The type of exercise that you are performing will play a significant role in the degree of weight imbalance that you can have in your adjustable dumbbells.
Exercises like bicep curls and lateral raises require a great degree of precision in the weights that you use. For exercises like bicep curls or lateral raises, you may have to opt for a lighter weight for the adjustable dumbbells than for exercises like a press. The reason for this is that if you choose a too heavy weight for a press exercise, it will be difficult to perform the exercise.
Exercises like rows or carries can have a greater weight difference between each of the adjustable dumbbells. The calculator allow you to adjust for the type of exercise that you are performing. Another consideration for using the adjustable dumbbell calculator is your inventory of weight plates.
The larger the plates that you have, the larger the increments of weight that you can add to the adjustable dumbbells. As such, the calculator will show you the next available weight that is lighter or heavier for the adjustable dumbbells. This feature allows you to see how many small weight plates you will need to purchase or if you can live with having to jump in weight for the adjustable dumbbell sets that you use.
The total number of weight plates that you have is another consideration to make before using the calculator. Even if an exercise seem good for a certain weight, the total number of plates that you have will mean that the exercise will require a number of plates that you do not own. To avoid this problem, the adjustable dumbbell calculator contains a mode setting that accounts for the total number of adjustable dumbbells that you will be using.
The mode setting will change the total weight that is determined when you switch from one adjustable dumbbell to two. Using the calculator will prevent you from buying adjustable dumbbells that you will not be able to use due to lack of plates. An important feature of the adjustable dumbbell weight calculator is the ability to perform unit conversions.
The value of the adjustable dumbbells may be in pounds, but the exercise program that you follow may indicate the weight in kilograms. Using the unit conversion feature will ensure that you do not add the incorrect amount of weight to the adjustable dumbbell due to rounding error in the conversion of units. The math will be the same, but the numbers will be easy to read on the adjustable dumbbell calculator.
The grip strength that you possess while performing exercises will also change the weight of the adjustable dumbbells that you feel you can endure. The same amount of weight will feel correct for the first set of exercises but too heavy for the fourth set of exercises due to exhaustion of the muscles that you are using or the thickness of the handles for the adjustable dumbbells. Even though the adjustable dumbbell calculator will not account for your grip strength, the calculator ensure that the weight of the adjustable dumbbells will remain the same for the workout so that you can focus on the exercises instead of the unbalanced adjustable dumbbells.
The reference tables included on the adjustable dumbbell calculator page include explanations of common terms and scenarios. The adjustable dumbbell calculator is essential for adding the weights of the adjustable dumbbell, and it is easy to make an error when adding these numbers. The reference tables will help you to understand the different terms and how the examples will round to make it easier for you to determine the total weight of the adjustable dumbbells.
The main value of the adjustable dumbbell calculator is that it makes it easier for you to calculate the weights of the adjustable dumbbells. Once you have entered your information into the adjustable dumbbell calculator, you will be able to save the information so that the calculator will calculate the weights for every session in the future. This will allow you to save time adding the numbers together each time you want to calculate the weight.
It is a good idea to check the inventory of the adjustable dumbbells that you have before you begin any new phase in your training. Based off the calculations from the adjustable dumbbell calculator, you may be required to purchase additional small plates for the adjustable dumbbells. You should make your decision based on the data from the adjustable dumbbell calculator then on your gut feeling about how the adjustable dumbbells may feel during the exercise.
