Shoulder Sit
A Prep-level stunt where the top person sits on the shoulder or shoulders of a base. Shoulder Sits are useful for developing trust, body control, base posture and creative pyramid structures while keeping the stunt relatively close to the supporting athlete.
The flyer must maintain their own posture and balance rather than collapsing their full weight onto the base's neck or upper body. Loading and dismounting must be planned before the stunt begins.
What Is a Shoulder Sit?
A stunt where the top person sits on the shoulder or shoulders of a base.
IASF classifies the Shoulder Sit as a Prep-level stunt.
The flyer should remain actively balanced and upright while the base creates a stable structure beneath them.
Shoulder Sits can also be useful as bracing positions and visual levels within pyramids.
Strong from the Floor Up
Stable Stance
The base needs enough width and control to resist unwanted movement.
Stay Active
Lower-body control helps prevent the torso from collapsing.
Remain Upright
Avoid excessive forward or sideways lean under the load.
Stay Aware
Maintain awareness of the flyer and surrounding stunt area.
Sit Tall — Don't Collapse
Stay Centred
Keep weight organised directly over the supporting athlete.
Remain Active
The flyer should maintain their own torso position.
Lift Upward
Maintain an intentional performance posture.
Know the Plan
Upper-body placement should match the entry, bracing or choreography being performed.
Strong vs Weak Shoulder Sit
✓ Strong Structure
- Base feet remain stable.
- Base torso stays upright.
- Flyer hips remain centred.
- Flyer maintains active posture.
- Chest remains lifted.
- Minimal unnecessary movement.
- Entry is predictable.
- Exit is controlled.
✕ Weak Structure
- Base continuously shuffles.
- Base folds under the flyer.
- Flyer leans heavily to one side.
- Flyer collapses through torso.
- Weight presses into base's neck.
- Entry looks improvised.
- Flyer moves without communication.
- Dismount is uncontrolled.
Shoulder Sit Flow
Progression Framework
Develop lower-body and torso stability.
Teach active upright posture at floor level.
Learn exactly how weight will transfer.
Prioritise balance before choreography.
Return safely on shared counts.
Add visual presentation without changing balance.
Introduce legal bracing and structure roles.
Development Drills
Posture Holds
Practise a stable upright stance before adding load.
Seated Core Holds
Develop active posture rather than passive sitting.
Load → Freeze
Pause at the first stable frame to assess alignment.
Front View
Check side-to-side flyer lean and base alignment.
Side View
Check torso posture and centre of mass.
Matched Counts
Synchronise loading and presentation across groups.
Short Coaching Cues
Common Problems & Fixes
| What You See | Likely Cause | Check First | Training Direction |
|---|---|---|---|
| Base leans sideways | Flyer weight off centre | Flyer hips | Rebuild controlled loading. |
| Flyer collapses downward | Passive torso | Core and posture | Return to seated posture drills. |
| Base keeps moving feet | Stance or load unstable | Initial setup | Reduce duration and reset. |
| Flyer twists | Uneven weight placement | Hip alignment | Re-centre before holding. |
| Groups hit at different times | Count inconsistency | Loading count | Rehearse without stunting. |
| Dismount feels rushed | Exit not planned | Final counts | Train exit independently. |
IASF Shoulder Sit Context
Execution · Stability · Uniformity · Sync
A Shoulder Sit should appear deliberate and stable rather than simply surviving because the flyer is close to the base.
Consider the Complete Construction
Participation, use of bases, transitions, combinations and pace affect the overall comparative difficulty picture.
