Maximum Bench Press

What is a Max Bench Calculator?

A max bench calculator is used to estimate the one rep max (1RM) of the bench press exercise. The one rep max is the maximum amount of weight that someone can lift at any given time. For this reason, people use a max bench calculator to help them determine their max bench press.

The bench press is a big part of most powerlifting and bodybuilding programs. It's one of the "big three" lifts alongside the squat and the deadlift. The bench press mostly works the muscles in the chest, shoulders, and triceps.

How to Use this Max Bench Calculator

It's very easy to use our max bench calculator. You just need to enter the following information:

First, choose your preferred unit: Pounds (lbs) or Kilograms (kg)
Next, type in the weight that you lifted
Then enter the repetitions performed
Push the "Calculate Max Bench" button and let the magic happen!

The information that you entered will then appear in the "Results Box". From there, you can start interpreting the results

Pro Tip: For the best results, use a weight that is about 80% - 90% of your true 1RM

How it Works

Our max bench calculator works with two formulas:

Epley Formula: 1RM = Weight × (1 + 0.0333 × Reps)

Brzycki Formula: 1RM = Weight × (36 / (37 - Reps))

The Epley formula is probably the most popular one for max bench calculations. It has stood the test of time and gives excellent results for most people. The Brzycki formula is slightly more accurate for lower rep ranges (1-10).

As promised, our max bench calculator is using both formulas and giving you the average so that you can see the most accurate results.

Why Should You Know Your Max Bench Press?

There are a lot of reasons why someone should know their max bench press.

The first and most obvious reason is that most training programs, especially for powerlifting, are based on percentages of one's max. For example, a 5x5 powerlifting program usually involves 75-85% of your max bench.
The second reason is that knowing your max bench press helps you track your progress. If you start using a max bench calculator every week or every month, you can easily see if you're getting stronger.
The third reason is that this information can help you set realistic short and long-term goals.
And, the last reason is that testing your max bench is very dangerous, especially if you don't have a spotter.

The Bench Press Strength Calculator (Based on Body Weight)

The idea is that the max bench press strength calculator below compares your max to the standard max based on body weight.

Level	Bench Press (Men)	Bench Press (Women)
Beginner	0.5x body weight	0.3x body weight
Novice	0.75x body weight	0.5x body weight
Intermediate	1x body weight	0.65x body weight
Advanced	1.5x body weight	1x body weight
Elite	2x body weight	1.3x body weight

How to Increase Your Max Bench Press

Here are some proven ways on how to increase your max bench press:

Progressive Overload: To increase your max bench press, you need to gradually increase the amount of weight, reps, or sets over time.
Accessary Work: To build a bigger bench press, you need to do more than just bench presses. You need to do work to develop your triceps, delts, and upper back.
Perfect Form: To maximize your max bench, you need to perfect your technique and use your legs.
Periodization: To really drive your max higher, you need to periodize your training.
Proper Recovery: To recover properly, you need to get enough sleep and eat healthy.

How Not to Use a Max Bench Calculator or Test Your Max Bench Press

Some common sense mistakes to avoid when using a max bench calculator or testing your max bench press.

Don't use too high a rep range: Max bench calculators are most accurate for 1-10 reps.
Don't sacrifice form for heavier weight: This goes without saying, but when it comes to max bench, it can be tempting to use poor form to lift more weight.
Warm-up Sets: Always use warm-up sets. Never attempt to test your max without a warm-up set.

The Anatomy of the Bench Press (Muscles Worked)

To really understand the bench press and how to maximize it, it's helpful to have a general understanding of which muscles are doing most of the work. The biggest muscle group worked during the bench press is the pectoralis major or simply the pecs. Other major muscles worked during the bench press are:

The anterior deltoids or front delts
The triceps brachii or triceps
The rotator cuff
The latissimus dorsi or lats

The bench press is a compound movement, which means that it's working multiple muscles at the same time. It's also helpful to understand that the lats provide a stable base for the bench press and help with the leg drive, which is a very important part of the bench press.

Equipment Matters: Barbell vs. Dumbbell

You can use dumbbells or a barbell for the bench press. However, it's important to know that the equipment that you use makes a difference in your 1RM. This max bench calculator is for the barbell bench press, but if you want to know your dumbbell 1RM, keep reading.

Using dumbbells for the bench press is a great way to develop your stabilizer muscles because you have to do more work to keep the dumbbells from falling. However, your dumbbell 1RM will be lower compared to your barbell 1RM simply because you have two weights with a wider range of motion to press.

As a rule of thumb, your dumbbell 1RM will be roughly 75-85% of your barbell 1RM.

Bench Press Variations to Break Through Plateaus

If you're stuck at a certain weight and can't seem to increase your max, it's a good idea to switch up your routine and try different variations of the bench press. The most popular variations include:

Close-grip bench press: This variation focuses more on the triceps and can be a good accessory movement for the bench press.
Incline bench press: This is another good variation that isolates the upper chest and front delts.
Pause bench press: This variation requires you to pause at the bottom of the movement for a second or two, which increases the difficulty of the movement.
Board press: This variation involves pressing the bar against a board that's mounted above your chest. It's useful for increasing the strength off the chest and building up to a higher max.

FAQs About Max Bench Calculator

What is a good max bench?

A good max bench press depends on what you're comparing it to. In general, a good max bench for men is 1x body weight and a good max bench for women is 0.75x body weight.

How accurate is the max bench calculator?

The max bench calculator is very accurate. It uses the Epley and Brzycki formulas that have been proven to work for all rep ranges (1-10). As always, your true 1RM may vary depending on the day and your mental and physical state. Never attempt to do a true 1RM without a spotter.

Can I use this calculator for other exercises?

Yes, the max bench calculator works for any exercise. Just make sure to use the right unit and enter the correct information.

Why does my calculated 1RM feel so hard?

Remember that this calculator only gives you a theoretical maximum based on a mathematical model. There are many factors that can affect your real-world 1RM. Always use a spotter when doing a true 1RM.

Should I test my 1RM every week?

No, you shouldn't test your true 1RM that often. It takes a lot of energy and recovery time to recover from testing your 1RM. Most people can only do it every 8-12 weeks during a "peaking" phase. For day-to-day tracking, use this max bench calculator.
