📖 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.

Walking Lunges with Trunk Rotation

Draftfunctional75%intermediate⬤ moderate evidence
View FHIR resourceFHIR R4 ActivityDefinition — the interoperable form of this exercise

Positions & Range of Motion

Start
standing tall, feet together, ready to step forward into a lunge
End
in the bottom of a forward lunge (front knee tracking over the toes, back knee near the floor) with the trunk rotated toward the front leg, then returned before stepping through to the next lunge
Range of Motion
large hip and knee flexion of the lunge combined with thoracic rotation toward the lead leg; alternating stepping gait

How to Perform

Step into a forward lunge. At the bottom, rotate the trunk toward the front leg, then return. Step the back foot forward to begin the next lunge on the other side. Integrates lower-body load with thoracic mobility.

Coaching Cues

  1. 1

    Front knee tracks over toes; back knee close to floor

    (verbal)
  2. 2

    Rotate from the upper back, not the low back

    (verbal)

Evidence-Based Dosing & EMG Data

Recommended Dosing

5 reps each side.

Muscles Involved (17)

Primary Movers

Quadriceps Femoris— Extends the front knee to lower into and rise out of the lunge, with eccentric control on descent.
Gluteus Maximus— Primary hip extensor driving the front leg upward and forward out of the lunge.
External Oblique— Contralateral trunk rotator; turns the trunk toward the front leg at the bottom of the lunge.
Internal Oblique— Ipsilateral trunk rotator working with the opposite external oblique to rotate toward the front leg.

Secondary Movers

Hamstrings (Group)— Assist hip extension and provide eccentric control of knee flexion during the lunge.
Adductor Magnus— Assists hip extension and stabilizes the loaded front hip in the split stance.
Gastrocnemius— Plantarflexes to assist push-off, driving the back foot forward into the next step.
Soleus— Ankle plantarflexion and stability during push-off and single-leg loading.
Rotatores (Thoracis)— Deep segmental thoracic rotators contributing to the upper-back rotation.
Erector Spinae Group— Extend and stabilize the trunk against forward-lunge flexion torque and assist rotation.

Stabilizers

Gluteus Medius— Controls frontal-plane pelvis position on the loaded stance leg.
Gluteus Minimus— Assists gluteus medius in pelvic stabilization of the stance leg.
Tensor Fasciae Latae— Helps stabilize the hip and pelvis during the split-stance load.
Transversus Abdominis— Provides intra-abdominal/core stability during the loaded rotation.
Multifidus— Segmental spinal stabilizer supporting controlled thoracic rotation.
Quadratus Lumborum— Stabilizes the lumbopelvic region against rotational and lateral load.

Lengthened / Stretched

Iliopsoas— Trailing-leg hip flexor is stretched as the rear hip moves into extension at the bottom of the lunge.

Easier Variations ↓

1

Stationary Lunge with Rotation

Stay in place; don't walk the lunge forward.

Harder Variations ↑

1

Loaded Lunge with Rotation

Hold a medicine ball or dumbbell during rotation.
