Trust Line

Choose this exercise

Purpose: Demonstrate rotating physical support and structured verbal readiness calls in an in-person line formation.

Use it when: Use during in-person workshops when groups have established basic physical safety norms and members consent to physical spotting.

Skip it when: Skip when participants avoid physical contact, have balance or spine constraints, or lack open floor space.

Group arrangement: One central volunteer between two facing lines of 3 to 8 spotters each; an extra participant can serve as safety observer.

Timing: UWT suggested duration to allow demonstration, verbal protocol setup, several volunteer rounds, and debrief.

Materials and tools

• No special materials.

Before participants arrive

1. Clear a flat, unobstructed floor area of at least 4 by 4 meters with level, non-slip footing.

Say this to open

Today we will run Trust Line. One person volunteers to stand in the center and lean forward or backward with a firm posture. Two facing spotters catch and return the volunteer to center. Each spotter steps out after a catch so the line continually advances. Participation is fully voluntary. You may spot, serve as visual safety observer, or sit out entirely.

How to run it

1. Set safety stances and verbal protocol 3 minutes

   Demonstrate the faller stance: feet together, arms crossed over the chest, body firm. Demonstrate the spotter stance: one foot back in an athletic lunge, hands up at chest level, eyes forward. Teach the call sequence. The faller asks, 'Spotters ready?' Both active spotters answer, 'Ready.' The faller calls, 'Falling,' and spotters answer, 'Fall on.' Only then does the faller lean.

2. Form lines and position first volunteer 2 minutes

   Arrange the group into two facing lines about one meter apart. If numbers are uneven, place the extra person as an outside safety observer. Invite one volunteer into the center space between the head spotters. Confirm the first pair of spotters is in athletic stance.

3. Execute rotating catches 7 minutes

   The faller speaks the readiness calls and leans toward one spotter. That spotter cushions the upper back or shoulders and guides the faller back to center toward the opposite partner. Once that spotter completes the return, they step out to their left and join the back of the facing line. The next person in line steps into the spotter stance. The opposite spotter then catches, returns, and rotates out in the same manner. Rotate the central volunteer every 30 seconds for 3 to 5 rounds.

4. Debrief spotting dynamics 3 minutes

   Gather in a circle. Invite two or three participants to share how the verbal checks and spotter changes affected their sense of stability.

Debrief questions

• What difference did the verbal readiness calls make before each lean?
• How did the continuous rotation of spotters affect your focus as a spotter or faller?

Finished output: Completion of structured spotting rotations with confirmed readiness calls across participating volunteers.

Remote

This physical spotting exercise cannot be run online. As a separate non-physical communication alternative, run a sequential verbal countdown where participants count from 1 to 20 without speaking simultaneously.

Hybrid

This exercise is in-person only due to physical spotting requirements. Remote attendees cannot share the physical mechanic; offer them the separate non-physical countdown alternative in a dedicated video breakout.

Access and participation choices

• Participants may choose to serve only as a spotter, act as a visual safety observer, or pass entirely without explanation.
• Any participant can stop the rotation instantly by stepping back to center or saying 'stop'.

If the session gets stuck

A spotter pushes the faller too hard instead of easing them upright.

Pause the round. Remind spotters to absorb the person's weight and guide them gently back to vertical rather than thrusting them across.

The faller bends at the hips rather than maintaining a straight posture.

Ask the faller to reset, lock their core, keep their arms tucked close, and take a much shallower lean.

Terms used here

• Spotter stance: An athletic stance with one foot behind the other, knees flexed, and hands raised forward to cushion weight safely.
• Readiness calls: A standard call-and-response phrase sequence used to confirm both spotters are ready before any lean begins.
