Muscle Balance Ratio Calculator

Evaluate your push/pull, quad/hamstring, and upper/lower strength balance. Identify weak points and reduce injury risk with ideal ratio analysis.

About this calculator

Each ratio here compares exactly two of your six entered lifts and ignores the rest — Push:Pull is Bench Press divided by Barbell Row and responds to nothing else, Squat:Deadlift is Squat divided by Deadlift, and so on. Raising the numerator lift always pushes its ratio up; raising the denominator lift always pulls it down, so Bench Press and Barbell Row move Push:Pull in opposite directions while Overhead Press, Squat, Deadlift, and Leg Curl have no effect on it at all. Balance Score averages five deviation scores, one per ratio, each built from 100 minus the ratio's distance from its ideal value (scaled by that ratio's tolerance) and floored at zero — a ratio sitting exactly on its ideal value (1.0 for Push:Pull, 0.82 for Squat:Deadlift, 0.7 for Bench:Squat, 0.65 for OHP:Bench, 0.55 for Ham:Quad) scores 100 for that component, and the further off-target you are relative to that ratio's tolerance band, the more it drags the average down.

Upper:Lower Ratio is the only ratio computed from more than two lifts — it sums Bench Press and Overhead Press over Squat plus Deadlift — so it is the one number here where all four of those inputs genuinely matter together. These targets come from general strength-standards research, not from your injury history or sport, so treat "imbalanced" as a prompt to investigate, not a diagnosis.

How to Use This Calculator
  1. Enter your estimated 1RM for Bench Press, Barbell Row, Overhead Press, Back Squat, Deadlift, and Leg Curl.
  2. Review the Overall Balance Score and individual ratios (Push:Pull, Squat:Deadlift, Bench:Squat).
  3. Check each Assessment rating to identify which muscles are lagging.
  4. Use the recommendations to adjust programming and reduce injury risk.

What each input means

Bench Press 1RM
Your max bench press. Use an estimated 1RM if you do not test singles.
Barbell Row 1RM
Strict barbell row max (Pendlay or bent-over). Should roughly match bench press.
Overhead Press 1RM
Standing strict overhead press max. Typically 60-70% of bench press.
Back Squat 1RM
High bar or low bar back squat one-rep max.
Deadlift 1RM
Conventional or sumo deadlift one-rep max. Typically 10-20% higher than squat.
Leg Curl 1RM
Lying or seated leg curl max. Used to assess hamstring strength relative to quads.

Frequently Asked Questions

Why does entering my Squat and Deadlift not change my Push:Pull Ratio?

Push:Pull Ratio is calculated only from Bench Press divided by Barbell Row — none of the other four lifts (Overhead Press, Squat, Deadlift, Leg Curl) appear in that formula at all. Each ratio on this page reads from exactly the two lifts named in its label, so entering your leg numbers only affects the ratios that name legs.

Does a higher Barbell Row number make my Push:Pull Ratio better or worse?

It moves the ratio down, the opposite direction from Bench Press. Push:Pull Ratio is Bench Press divided by Barbell Row, so raising the row (the denominator) while holding bench fixed lowers the ratio toward or below the 1.0 ideal, which the assessment reads as "pull dominant" rather than push dominant.

What makes Upper:Lower Ratio different from the other five ratios?

It's the only ratio built from more than two lifts: it sums Bench Press and Overhead Press for the numerator and Squat plus Deadlift for the denominator. Every other ratio on this page (Push:Pull, Squat:Deadlift, Bench:Squat, OHP:Bench, Ham:Quad) compares exactly two entered maxes, so Upper:Lower is the one figure where all four of those lifts matter together.

How is Balance Score different from just averaging the six ratios?

Balance Score does not average the raw ratio values — it averages five deviation scores, one per ratio (Upper:Lower is not included), each starting at 100 and losing points the further that ratio sits from its own ideal value relative to its own tolerance band. A ratio exactly on target scores 100 regardless of what the ideal number itself is, so ratios with very different ideal values (1.0 vs. 0.55) still contribute on the same 0-100 scale.
