10 dimensions · 68 metrics · Testing is always free

Test first.
Train right.

BodyBench is an AI fitness testing app for iPhone. Ten minutes of standardized testing tells you which of your 10 performance dimensions is holding you back. Coach then builds a four-week block to fix it, and retests it when the block ends.

Where we differ

Most fitness apps ask what you want to do

BodyBench starts by measuring what your body can do. Every plan that follows is built on that, instead of on your answers.

vs. plan generators

They ask what you want. We measure what you've got.

vs. recovery wearables

Recovery is half the story. What can you actually do?

vs. workout logs

Logging isn't testing. A PR log can't tell you your weakest link.

vs. lab assessment

Not a lab in your pocket — a lab you'll actually use every four weeks.

Inside the app

Every number shows its work

These are screenshots, not mockups. Real scores from a real dataset, with the reasoning left in.

One score you can act on

Body Score puts seconds, kilos and centimetres on the same 0–100 scale. It never appears without the group it was measured against, so a 68 always comes with who that 68 is being compared to.

Body Score 68, marked Good tier versus men 30-39, above a Coach insight explaining that squat, bench and deadlift 1RMs sit good-to-elite but aren't converting into single-leg stability.

Coverage, not just scores

Each dimension shows how much of it you've actually tested. A 79 built on 3 of 6 tests isn't the same as a 79 built on all six, and the card tells you which one you're looking at.

Eleven dimension cards showing Cardio 79 with 3 of 6 tested, Strength 86 with 6 of 15 tested, Power 59, Endurance 78, Mobility 59, Balance 61, Agility 60, Neuro 75, Body Comp 62, plus Recovery and Posture as trends.

Every exercise carries its reason

Each movement in the session says which limiter it targets, in one line, before you start it. If you can't see why an exercise is there, it shouldn't be there.

Week 1 Day 1 session: back squat at 70 percent to maintain the strength base, single-leg RDL with right-leg emphasis, and an overcoming isometric single-leg stance to retrain the flagged right-leg proprioceptive deficit.

A six-month map, not just next week

Each four-week block sits inside a longer plan that carries its own numbers: single-leg gap under 10%, EUR from 0.98 to 1.05, squat 1RM 213 → 220kg. You can read what month four is supposed to look like before you start month one.

Training Plan built for basketball, targeting left-right imbalance and reactive power, with a six-month roadmap: month one neuromuscular control and stability, month two stability under load, month three elastic capacity, month four strength-power conversion, each with numeric targets.
AI Coach

A coach that reads your file before it opens its mouth

Every reading starts from a deterministic mechanism layer, not a hunch. Coach explains what the data shows and turns it directly into next week's training.

✓Every score tells you who it was compared with: Good · vs men 30-39, never a number on its own.
✓Coach names the one or two dimensions holding you back, instead of listing everything you could improve.
✓It checks the evidence before it writes: asymmetry, H:Q ratio, EUR, RSI and FMS thresholds all go through fixed rules first.

Deterministic mechanism layer. AI narration. No invented data.

Coach
AI INSIGHT
You're strength-dominant in force production — Squat, Bench and Deadlift 1RM all sit good-to-elite. But that force isn't converting into single-leg stability, and that's what's capping your Power score.

The assessment

Ten dimensions, 68 metrics, one honest score

Each test is scored against real population norms for your age and sex, then normalized into one 0–100 Body Score. Seconds, kilos and centimetres finally become comparable.

Recovery (trend)

Posture is screened separately as an eleventh dimension and deliberately kept out of the Body Score. It's a flag to act on, not a number to average away.

The part nobody else does

Then it retests its own work

Four weeks after Coach names your limiter, it asks you to retest that same dimension and shows you whether the block moved it. A plan that can be proven wrong is the only kind worth following.

Who it's for

For people who want their training decisions backed by their own numbers

BodyBench isn't a step counter, and it isn't trying to be your whole fitness life. It answers one question well: what should you work on next, and how do you know it worked.

Two to five years in

"I feel like I'm spinning my wheels"

Your weight and your measurements still move, but you can't say whether you got stronger. Find out which mechanism is capping your lifts (asymmetry, reactive strength, something else) instead of adding volume and hoping.

No team behind you

Weekend competitor

Hyrox, five-a-side, a half marathon, a Sunday league. You don't have a physio and a strength coach on staff, so test before the season and after it and see what the training changed.

Returning from injury

Rebuild with evidence

Track left-right gaps and mobility trend over time, and let the plan gate exercises around what's still healing. These are estimates for training guidance, not a medical assessment.

Test results, training history and meal logs are stored on your phone. There is no server-side copy. When you tap to request an AI reading, a plan, or a meal or posture analysis, that one request goes through our backend to a third-party AI provider and the answer comes back.
