📖 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.

Kettlebell Swing (Two-Hand)

Draftstrength85%intermediatemoderate evidence
View FHIR resourceFHIR R4 ActivityDefinition — the interoperable form of this exercise

Positions & Range of Motion

Start
standing with feet shoulder-width, hips hinged and the kettlebell hiked back between the legs above knee height
End
hips snapped to full extension with a tall trunk as the kettlebell floats out to chest/shoulder height on nearly straight arms
Range of Motion
dynamic hip hinge cycling from hip flexion (bell above the knees) to full hip extension; bell arcs from between the thighs up to ~chest height

How to Perform

Explosive hip hinge swing to chest height. Hip hinge produces greater hamstring activation than squat swing (MD 3.92, p=0.002). Low back ~50% MVC, glutes ~80% MVC, spine compression ~3,200 N at 16 kg. Unique posterior shear L4 on L5. 8-week RCT: neck/shoulder pain -2.1 points, lumbar extensor strength increased. Acute swings increase pressure pain thresholds.

Coaching Cues

  1. 1

    Hinge, not squat — glutes snap the bell

    (verbal)
  2. 2

    Snap the hips forward to launch the bell to chest height

    (verbal)
  3. 3

    Hike the bell back between the legs above the knees

  4. 4

    Hips fire like a slingshot, arms only the rope

Evidence-Based Dosing & EMG Data

Recommended Dosing

Cardio: 15:15 protocol 20 min 3x/week. Strength: 3-5×8-10 at 8-10RM. Pain: 8 rounds 20s swings/10s rest [Falatic 2015, Keilman 2017]

EMG Activation Data

Hip hinge: hamstrings MD 3.92 vs squat swing (p=0.002). Medial hamstrings > BF (MD 9.93, p=0.022) [Del Monte 2020]. Low back ~50% MVC, glutes ~80% MVC [McGill 2012]

Muscles Involved (5)

Primary Movers

Gluteus Maximus~80% MVC explosive hip extension [McGill 2012]
Hamstrings (Group)Significantly higher with hip hinge technique [Del Monte 2020]

Secondary Movers

Erector Spinae Group~50% MVC trunk rigidity [McGill 2012]
Quadratus LumborumLateral stability

Stabilizers

Easier Variations ↓

1

Kettlebell Deadlift

Remove ballistic component. Practice hip hinge with load.

2

Wall-Facing Swing

12 inches from wall — forces hip hinge pattern.

Harder Variations ↑

1

Single-Arm Swing

Anti-rotation demand. RA ipsilateral 42-48% higher [Andersen 2016].

2

Kettlebell Snatch

Single-arm overhead finish. Advanced full-body power.

Research Notes

AUDIT[medium]: Specific spinal-load safety claims ('spine compression ~3,200 N at 16 kg', 'unique posterior shear L4 on L5') are stated without any linked citation; the sources array holds only Kisner/ACSM and inline brackets cover only dosing (Falatic, Keilman). → Attach the McGill kettlebell spine-load source for the compression/shear figures or soften the claim to a qualitative statement. AUDIT[low]: Lists ankle-plantarflexion as a movement but no plantarflexor muscle is included among its muscles. → Add gastrocnemius/soleus as synergist/stabilizer for the terminal plantarflexion, or drop the ankle-plantarflexion movement tag.
