📖 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.

Foam Roller Bridge

Draftstrength82%beginner-intermediate⬤ moderate evidence
View FHIR resourceFHIR R4 ActivityDefinition — the interoperable form of this exercise

Positions & Range of Motion

Start
supine with knees bent, heels resting on a foam roller, arms at the sides
End
hips lifted so knees, hips, and shoulders form a straight line, knees held hip-width
Range of Motion
0–~full hip extension, lifting the pelvis from the floor to the bridged straight-line position

How to Perform

Hip extension bridge with feet elevated on a foam roller. The unstable surface increases proprioceptive demand and alters muscle recruitment. Back bridge with leg lift on unstable surface produces L/G ratio of 3.35, indicating high lumbar-to-gluteal muscle challenge. Adding external rotation during bridging increases gluteus maximus and multifidus activation.

Coaching Cues

  1. 1

    Posterior pelvic tilt — glute lifts the hips, hamstrings co-act

    (verbal)
  2. 2

    Drive the heels into the roller to lift the hips

    (verbal)
  3. 3

    Aim the front of the hips toward the ceiling

    (verbal)
  4. 4

    Knees stay hip-width — hands check the gap

Evidence-Based Dosing & EMG Data

Recommended Dosing

3×10-15 reps with 5-10s holds at top, 2-3x/week

EMG Activation Data

L/G ratio 3.35 for back bridge with leg lift on unstable surface [Khosrokiani 2021]. Bridge with ER increases glute max and multifidus activation [El Melhat 2022].

Muscles Involved (6)

Primary Movers

Gluteus Maximus— Primary hip extensor — activation enhanced with ER [El Melhat 2022]

Secondary Movers

Hamstrings (Group)— Hip extension co-contraction — altered recruitment on unstable surface

Stabilizers

Multifidus— Segmental lumbar stabilization — increased with ER and unstable surface [El Melhat 2022]
Erector Spinae Group— L/G ratio 3.35 indicates high lumbar demand [Khosrokiani 2021]
Transversus Abdominis— Core bracing for pelvic stability on roller
Gluteus Medius— Pelvic control on unstable surface

Easier Variations ↓

1

Standard Bridge

Perform a regular bridge with feet flat on the floor. Remove the unstable surface challenge.

2

Foam Roller Bridge — Feet Wider

Place feet wider apart on the roller for a more stable base. Reduces balance demand.

3

Regress to bridge

AUDIT: Regress the unstable foam-roller bridge to a stable-surface bridge if pelvic control is lost.

Harder Variations ↑

1

Single-Leg Foam Roller Bridge

Extend one leg while bridging on the other foot on the roller. Significantly increases stability and glute demand.

2

Foam Roller Bridge with March

Hold bridge position on roller and alternately lift knees. Combines instability with dynamic hip flexion.

Research Notes

Back bridge with leg lift: L/G ratio 3.35 — high lumbar stabilizer demand [Khosrokiani 2021]. Bridge with external rotation increases glute max and multifidus activation [El Melhat 2022]. Foam roller adds proprioceptive challenge beyond standard bridge.
