# How To Calculate Magic Number in Bench | Arithmix

Learn how to calculate the magic number in bench with this comprehensive guide. Discover the formula and step-by-step instructions to help you optimize your workout routine and achieve your fitness goals.

Are you looking to improve your bench press performance? One way to do so is by calculating your magic number. This number can help you determine the ideal weight to lift for your sets, allowing you to maximize your gains and avoid injury. In this article, we'll explain what the magic number is, when it's valuable to calculate it, and how to do so.

## What Is Magic Number?

The magic number is the weight you can lift for a certain number of reps without reaching failure. It's the weight that allows you to complete all your sets with good form and without feeling excessively fatigued. This number is unique to each individual and can change over time as you build strength and endurance.

## When Is It Valuable To Calculate Magic Number?

If you're new to weightlifting, it may not be necessary to calculate your magic number right away. However, as you progress and start lifting heavier weights, it becomes more important to determine the appropriate weight for your sets.

Calculating your magic number can also be valuable if you're experiencing a plateau in your bench press performance. By determining the weight that allows you to complete all your sets without reaching failure, you can adjust your training plan and potentially break through the plateau.

## How To Calculate Magic Number

Calculating your magic number is a simple process. Start by warming up with a few light sets of bench press. Then, choose a weight that you think you can lift for 10 reps without reaching failure. Complete your first set with this weight, and rest for 2-3 minutes.

For your second set, increase the weight by 5-10 pounds and aim for 8 reps. Rest for another 2-3 minutes before moving on to your third set.

For your third set, increase the weight again by 5-10 pounds and aim for 6 reps. Rest for 2-3 minutes before completing your final set.

For your final set, increase the weight one last time by 5-10 pounds and aim for 4 reps. If you're able to complete all four reps with good form and without feeling excessively fatigued, you've found your magic number.

Remember, your magic number may change over time as you build strength and endurance. It's important to re-calculate it every few weeks or months to ensure you're lifting the appropriate weight for your sets.

By calculating your magic number, you can improve your bench press performance and avoid injury. Give it a try and see how it works for you!

## How Do You Calculate Magic Number in Bench

Bench itself isn’t naturally geared towards letting you calculate complex metrics like Magic Number. As an alternative, teams typically use products like Arithmix to import data from Bench and build out dashboards.

## What is Arithmix?

Arithmix is the next generation spreadsheet - a collaborative, web-based platform for working with numbers that’s powerful yet easy to use. With Arithmix you can import data from systems like Bench, combine it with data from other systems, and create calculations like Magic Number.

In Arithmix, data is organized into Tables and referenced by name, not by cell location like a spreadsheet, simplifying calculation creation. Data and calculations can be shared with others and re-used like building blocks, vastly streamlining analysis, model building, and reporting in a highly scalable and easy to maintain platform. Data can be edited, categorized (by dimensions) and freely pivoted. Calculations are automatically copied across a dimension - eliminating copy and paste of formulas.
