📖 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.
  • 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.

Positions & Range of Motion

Start
standing facing, beside, or diagonal to a box/step with one foot planted flat on top and trunk tall, pelvis level
End
fully upright standing on top of the box, working hip and knee extended, trailing toe lightly kissing the box or floor
Range of Motion
working knee moves from ~90° flexion to full extension with concurrent hip extension through the full step height (4–30 cm)

How to Perform

Stepping onto box from different directions. Lateral at 60% 5RM: VL 52.8%, VM 50.4%, glute med 42.8%. Standard: highest glute max/hamstrings. Crossover: highest glute med concentric. Step height matters: 8-inch VM 60% vs 4-inch 24% MVIC. In elderly, 30 cm step matches 60% 1RM resistance exercise.

Easier Variations ↓

1

Low Step (4 inches)

VM 24% MVIC — appropriate start [Brask 1984].

2

Hand Support

Fingertip touch on wall for balance.

Harder Variations ↑

1

Higher Step (8-12 inches)

VM 60% MVIC at 8 inches [Brask 1984].

2

Loaded Step-Up

Add dumbbells. Forces scale more than bilateral squat [Kipp 2022].

3

Lateral/Crossover

Crossover for highest glute med [Simenz 2012].
