1RM Bench Press Test: How to Do It and What It Says About Your Push Strength

The 1RM bench press test is, alongside the squat, the most widely used benchmark for measuring upper body maximal strength. Beyond its "social" value (it's the number everyone asks about at the gym), it's a genuinely useful metric for setting load percentages in strength and hypertrophy training.

Let's look at how to perform it safely and how to interpret the result beyond the raw number.

What does this test measure?

It measures the maximum load a person can move for one bench press repetition with correct technique: bar from the chest to full arm extension, with shoulder blades retracted and a stable base from the feet, glutes, and back on the bench. It reflects the maximal dynamic strength of the chest, anterior deltoids, and triceps.

Equipment needed

• Flat bench
• Olympic barbell and plates
• Adjustable-height rack/supports
• A spotter for assistance on max attempts (essential for safety)

Testing protocol

Direct method (true 1RM):

1. Progressive warm-up with sets of 8-10, 5, and 3 reps, increasing the load each set
2. From roughly 85% of the estimated 1RM, drop to 1 rep per set and increase the weight in small steps (2.5 kg)
3. Rest 3-5 minutes between attempts close to max
4. The 1RM is the heaviest load lifted with the bar touching the chest and full arm extension, using correct technique

Indirect method (recommended in most cases):

1. Submaximal test: max reps with a known load (70-85% of estimated 1RM, up to 8-10 reps)
2. Apply a prediction formula (e.g. Epley or Brzycki) to estimate the 1RM

Common mistakes

• Skipping the spotter on max attempts (a genuine safety risk)
• Allowing the bar to "bounce" off the chest to generate momentum (invalidates the pure strength measure)
• Changing grip width between assessments, which significantly affects the result

How to interpret the result

Level	Men (1RM / body weight)	Women (1RM / body weight)
Beginner	< 0.75x	< 0.5x
Intermediate	0.75-1.0x	0.5-0.75x
Advanced	1.0-1.5x	0.75-1.0x
Elite	> 1.5x	> 1.0x

For example, an 80 kg man bench pressing 90 kg would sit right at the line between "intermediate" and "advanced" (~1.1x body weight).

Related tests

The 1RM bench press pairs well with other upper body strength-endurance tests:

• Upper Body Maximal Strength Test (prediction) — an indirect alternative when you don't want to run a true 1RM
• Push-Up Test — assesses muscular endurance of the same muscle group with a similar movement pattern

Track your progress

Knowing your 1RM today is useful, but knowing how it's evolved over the last 6 months is what actually helps you adjust programming. With Movalytics you can log the assessment method, load and reps, let the app calculate the estimated 1RM, and visualize each athlete's absolute and relative-to-body-weight strength progression.

Frequently asked questions

Do I need to perform a true 1RM to program training? Not necessarily. An estimate from a submaximal test (using a prediction formula) is usually accurate enough for setting load percentages, with less risk and fatigue. How does grip width affect the result? A wider grip shortens the range of motion and usually allows you to move more load; a narrower grip increases the range of motion and triceps involvement. That's why it's essential to keep the same grip width across assessments. How often does it make sense to repeat the test? Every 8-12 weeks within a strength block, or at the end of a mesocycle focused on maximal strength.
