Strength + Endurance

Built for both.Know where you stand.

Enter your bodyweight, lifts and a recent run. See where you stand, how your two sides compare, and what’s limiting the rest of your profile.

What your assessment tells you.

Your result is more than a score. It shows where your combined performance sits, how your profile leans, and which side has the most room to improve.

Where you stand

Your Hybrid Score brings strength and endurance onto one benchmark, giving you a clear read on your overall hybrid performance.

  1. Novice0–39
  2. Intermediate40–59
  3. Advanced60–74
  4. Elite75–89
  5. World class90–100

What kind of athlete you are

Your strength-to-endurance balance shows whether your profile leans toward strength, toward endurance, or sits somewhere between the two. A high score can still lean heavily to one side.

What’s holding you back

The gap between your two sides reveals your limiter: the side with the most room to bring the rest of your profile up.

Strength and endurance are usually measured separately.

A squat in kilograms and a run in minutes have no common unit. Strendex places each one as a percentile of the same reference dataset, so the two can be compared and combined.

How it works

  1. 01

    Enter your numbers

    Bodyweight, your best bench, squat and deadlift, and a recent run: 3 miles, 5K, 10K, half or full marathon.

  2. 02

    Each side becomes a percentile

    Your lifts relative to bodyweight, and your run adjusted to a common distance, are each placed within the same reference dataset. The 70th percentile means you sit above roughly 70% of it.

  3. 03

    Get your Hybrid Score

    The two percentiles are averaged into one score from 0 to 100. Your tier and athlete type show where that score sits and how your two sides compare.

Your percentiles compare you with the reference dataset, not with other people who use Strendex. Publishing your result is optional and does not affect your assessment. Read the methodology
