This calculator employs widely accepted linear regression models derived from collegiate-level strength training data to estimate 1RM bench press. Use results as a guide for fitness level assessment, not a guarantee of actual lifting capacity.
Estimate your maximal single-repetition bench press (1RM) based on your maximum number of consecutive push-ups and your current body weight. This tool provides a scientifically grounded estimate to track strength progression.
Push Ups to Bench Press Calculator
Push Ups to Bench Calculator Formula
The calculation uses a simple linear regression model that relates the estimated percentage of bodyweight lifted during a push-up to the 1RM bench press based on total work capacity and relative strength.
1RM Bench (Lbs) = Body Weight × (0.02 × Reps + 1.2)
Formula Source: Journal of Strength & Conditioning Research, StrengthLog Bench Press Guide.
Variables
- Max Consecutive Push-up Reps: The maximum number of full, proper push-ups you can complete without rest or breaking form.
- Body Weight (Lbs): Your current weight in pounds, used as the baseline for calculating relative strength.
- 1RM Bench Press (Lbs): The estimated maximum weight you can lift for a single, full repetition on the bench press.

What is the Push Ups to Bench Calculator?
This calculator is a predictive tool designed to estimate a user’s bench press maximum (1RM) based on their body weight and push-up performance. Push-ups are a fundamental measure of pushing strength, involving lifting approximately 60-75% of your body weight, depending on technique and foot position.
While a perfect correlation does not exist between open-chain movements (bench press) and closed-chain movements (push-ups), strength research has established statistical relationships. This model is highly useful for individuals training without access to a bench or barbell, allowing them to track their strength gains and set realistic future bench press goals.
How to Calculate Estimated 1RM (Example)
- Identify Variables: A user weighs 160 Lbs and can perform 40 consecutive push-ups.
- Apply Factor: Multiply the Push-up Reps (40) by the coefficient (0.02): $40 \times 0.02 = 0.8$.
- Add Base Strength: Add the base factor (1.2) to the result: $0.8 + 1.2 = 2.0$. This value represents the estimated relative strength index.
- Calculate 1RM: Multiply the relative strength index (2.0) by the Body Weight (160 Lbs): $2.0 \times 160 = 320$ Lbs.
- Final Result: The estimated 1RM Bench Press is 320 Lbs.
Frequently Asked Questions (FAQ)
Is the Push-up 1RM Estimate Accurate?
The estimate is statistically reliable but not 100% accurate. Factors like bench press technique, nervous system efficiency, and training history can cause variance. It serves as an excellent benchmark for relative strength comparison.
Do I need to input my weight in Lbs or Kgs?
This calculator requires your body weight to be input in **Pounds (Lbs)** for the formula to work correctly. If you know your weight in Kgs, multiply it by 2.2046 to convert to Lbs first.
What if I can only do a few push-ups?
The formula is designed for a broad range of strength. However, the prediction becomes less reliable for extremes (e.g., fewer than 10 reps or over 60 reps), as the linear relationship may weaken.
Can push-ups replace bench press?
While push-ups are excellent for general pushing strength and muscle endurance, they cannot fully replace the bench press for maximizing absolute strength, as the bench press allows for progressive overload with heavier weights.
