Overhead Press 1RM Test: Protocol, Tables, and Common Mistakes

The overhead press 1RM test assesses maximal vertical push strength, a very different pattern from the bench press (horizontal push) and one with greater demands on shoulder and core stability. It's a good indicator of the health and functional strength of the shoulder complex.

What does this test measure?

It measures the maximum load a person can lift for one repetition of the overhead press (bar from the shoulders to full overhead arm extension), standing, either without leg drive (strict) or with controlled leg drive (push press), depending on the chosen variant. It reflects the maximal strength of the deltoids, triceps, and shoulder and core stabilizers.

Equipment needed

• Olympic barbell and plates
• Rack with adjustable height for the starting position
• Optional: weightlifting belt

Execution protocol

Direct method (true 1RM):

1. Progressive warm-up with sets of 5-8, 3-5, and 2-3 repetitions, increasing the load
2. From ~85% of the estimated 1RM, drop to 1 repetition per set and increase the load in small increments
3. Rest 3-5 minutes between near-maximal attempts
4. The 1RM is the maximum load lifted with full overhead arm extension, without leg drive (if assessing the strict variant) and without excessive lower-back hyperextension

Indirect method (recommended):

1. Submaximal test: maximum repetitions with a known load (70-85% of estimated 1RM)
2. Apply a prediction formula (Epley or Brzycki) to estimate the 1RM

Common mistakes

• Using leg drive in the "strict" variant (this would make it a push press, a different variant)
• Allowing excessive lower-back hyperextension to "help" complete the movement, which can cause lower-back discomfort
• Not fixing the variant (strict vs. push press), since the difference in load moved between the two is considerable

How to interpret the result

Level	Men (1RM / body weight)	Women (1RM / body weight)
Beginner	< 0.4x	< 0.25x
Intermediate	0.4-0.6x	0.25-0.4x
Advanced	0.6-0.85x	0.4-0.6x
Elite	> 0.85x	> 0.6x

The overhead press tends to show notably lower relative values than the bench press, since it works against gravity through a greater range of motion and with less assistance from other muscle groups.

Related tests

The overhead press 1RM pairs well with:

• Bench press 1RM test — to compare horizontal vs. vertical push strength
• Upper-body maximal strength test (prediction) — an alternative method to estimate upper-body strength without a true 1RM

Track and monitor

Vertical push strength is a good indicator of functional shoulder health, especially in athletes who train the bench press heavily but neglect the overhead press (a common imbalance). In Movalytics you can record the method used, the variant (strict or push press), load and reps, and track the progression of vertical push strength alongside your other maximal strength tests.

Frequently asked questions

Why is it important to train and test the overhead press if I already do bench press? Because they work different patterns, and a marked imbalance between horizontal and vertical push can be a risk factor for shoulder health in the long run. What's the difference between the strict overhead press and the push press? The strict version doesn't allow leg drive (it assesses pure upper-body strength); the push press uses a small leg drive, allowing more load to be moved (it assesses power more than strength). Is this a good test for people with shoulder discomfort? In people with active shoulder discomfort, this test should be applied with caution or avoided, prioritizing pain resolution and recovery of range of motion with a physiotherapist first.
