Energy 1-10
Energy 1-10 is a calibration exercise in which a facilitator calls out a number from one to ten and performers immediately adjust their physical energy level to match. One is nearly motionless; ten is maximum sustainable physical exertion. The exercise trains rapid energy responsiveness, the ability to modulate physical commitment on command, and ensemble awareness of shared energy levels during warm-up.
Structure
Setup
All performers stand in an open space. No special arrangement is required. The facilitator stands to the side or in the center.
Progression
The facilitator calls a number. All performers immediately adjust their movement, voice volume, and physical intensity to match the called level: at "1" they barely breathe and barely move; at "5" they walk with purpose, speak at a moderate volume, and engage lightly with the space; at "10" they move at full speed, make full use of the space, and may vocalize.
The facilitator calls numbers in sequence, randomly, or with deliberate gaps -- jumping from 2 to 9, dropping from 8 to 3 -- to practice quick calibration rather than gradual transition.
The exercise is typically run for three to five minutes as a warm-up before more structured scene work.
Conclusion
The facilitator brings the group to a "5" or "6" -- a neutral, ready state -- and transitions directly into the next activity.
How to Teach It
Objectives
Energy 1-10 develops physical energy range, ensemble synchronization, and the ability to respond to an external cue instantly. It also gives facilitators a shared vocabulary for adjusting group energy during sessions: "Let's bring it to a seven" becomes a useful sidecall because the scale has been internalized.
How to Explain It
"One is barely alive. Ten is everything you've got. When I call a number, that's your energy level right now -- move, speak, breathe at that level until I change it."
Scaffolding
Begin with the extreme ends of the scale (1 and 10) before introducing middle numbers. The contrast helps performers feel the full range before calibrating within it. Once the range is established, practice rapid transitions -- 10 to 1 in a single breath.
Common Pitfalls
Performers at high numbers often rely on speed alone, losing physicality and presence in the rush. The coaching note is that high energy is not the same as high speed -- a "10" who is fully present in their body reads differently from someone who is simply running around. Similarly, "1" is not inactivity; it is maximum inner intensity with minimum external movement.

Related Exercises
No Doubles 1-10
No Doubles 1-10 is a group focus exercise in which players attempt to count from one to ten without any two people speaking at the same time. If two voices overlap, the count resets to one. The exercise demands acute group awareness and the willingness to both assert and yield. It is a simple but effective diagnostic for ensemble listening.
Supernova
Supernova is a high-energy group exercise in which performers start small and gradually build a collective physical and vocal explosion of energy, reaching a peak and then returning to stillness. The exercise calibrates the group's dynamic range and teaches players to build and release energy together.
Zulu
Zulu (1) is an energetic warm-up exercise in which players perform a series of synchronized group movements and chants, building collective rhythm and physical energy. The call-and-response format creates strong group cohesion and raises the energy level quickly. The exercise is commonly used as a pre-show warm-up to unite the ensemble.
Volcano
Volcano is a group warm-up exercise in which the ensemble builds collective vocal and physical energy gradually from silence to a full explosive release, then returns to silence. The exercise calibrates the group's shared energy and teaches performers to build and release intensity together as a single unit. It functions as an energizer and ensemble-synchronization exercise.
Machines
Machines is a group exercise in which players collectively build an imaginary apparatus by adding interlocking physical movements and sounds one performer at a time. A facilitator may call out a theme or type of machine, prompting the group to adapt their contributions accordingly. The exercise trains ensemble listening, physical expressiveness, and creative collaboration.
Crescendo
Crescendo is a group energy exercise in which the ensemble gradually builds sound, movement, or emotional intensity from complete stillness to a peak, then releases back to silence. The exercise trains dynamic control, group sensitivity, and the ability to ride a shared wave of energy without any single player driving the escalation. Crescendo demonstrates the dramatic power of collective escalation and release, teaching performers that the contrast between quiet and loud, stillness and movement, creates more impact than sustained high energy alone.
