📖 Static demo — read-only snapshot
You’re browsing a static build of the Body IQ knowledge graph, so everything loads with no backend. A few things that need the live server are turned off here:
- Global search (sidebar) is disabled — it queries the API.
- The JSON API and the API “Try it” playgroundaren’t included.
- FHIR resources are build-time snapshots served as static files, not the live /api/exercises/<slug>/fhir route.
- The data is a snapshot — it refreshes only when the demo is rebuilt, not live from the database.
Everything else — the body map, progression ladders, coverage heatmap, exercise finder, and all anatomy/exercise/source pages — works fully. The full app (live search + API + database) runs from the source on GitHub.
Push-Up
Why Include This
The reference horizontal pressing pattern — the standard against which incline and knee variants are graded, and the entry point for the harder narrow-base and unilateral variants.
Evidence basis: expert-opinion
Positions & Range of Motion
- Start
- prone plank position, hands under the shoulders, feet together, shoulders-hips-ankles in one line
- End
- elbows extended, scapulae protracted at lockout, trunk line unchanged
- Range of Motion
- full elbow flexion to extension; chest to within a fist's width of the floor
How to Perform
The floor push-up: a closed-chain horizontal press supporting roughly two-thirds of bodyweight through the hands, with the trunk held as a rigid lever from shoulders to ankles.

Coaching Cues
- 1
Screw your hands into the floor as you press
(verbal) - 2
Squeeze your glutes so your hips travel with your chest, not behind it
(verbal) - 3
Keep your elbows about 45° from your ribs, not flared to the sides
(verbal)
Evidence-Based Dosing & EMG Data
3×5–12, 2–3×/week (consensus programming, not RCT-derived)
Muscles Involved (9)
Primary Movers
Secondary Movers
Stabilizers
Easier Variations ↓
Knee Push-Up
Regress to Knee Push-Up. Moving the ground-contact point from knees to toes lengthens the resistance arm; roughly 50% to 65% of bodyweight at the hands.
Harder Variations ↑
Diamond Push-Up
Progress to Diamond Push-Up.
Archer Push-Up
Progress to Archer Push-Up.

Research Notes
claude-researched 2026-08 (bodyweight ladders). Rung ordering is community consensus, not trial evidence — see source bodyweight-progression-consensus-2026. EMG and RCT sourcing pending.
