Aerobics
Aerobics is a physical warm-up exercise in which one player leads the group through exaggerated, often absurd exercise movements. The leader adopts the persona of a fitness instructor and guides the ensemble through increasingly ridiculous physical routines, all performed with full commitment. Participants mirror the leader's movements and match their energy regardless of how outlandish the routine becomes. The exercise serves multiple functions in improv training: it raises the group's physical energy at the start of a rehearsal or class, breaks down self-consciousness by requiring participants to look foolish together, and establishes a shared physical vocabulary before scene work begins. Aerobics belongs to a family of physical warm-ups that draw from fitness disciplines such as yoga, tai chi, and martial arts, adapted for the specific needs of ensemble performance training.
Structure
One player steps forward as the leader and adopts the character of a fitness instructor. The rest of the group arranges themselves so they can see the leader clearly, typically in rows facing the same direction.
The leader begins with simple, recognizable exercise movements such as stretching, jumping jacks, or jogging in place. As the warm-up progresses, the leader escalates the movements into increasingly absurd or exaggerated territory. The movements may become physically impossible, comically specific, or narratively driven. The group follows along with full commitment, matching the leader's intensity and enthusiasm.
The leader may incorporate verbal cues, counting, motivational phrases, or character choices to heighten the absurdity. The exercise continues for five to ten minutes or until the group has reached a high energy state. The leader concludes by bringing the group back to a resting state or by ending on a final ridiculous flourish.
How to Teach It
How to Explain It
"We are doing an aerobics class. I am your instructor. Follow along. Keep moving. The energy you bring in the next sixty seconds is the energy the room starts with. Ready? And."
Aerobics works best as the opening exercise in a rehearsal or class session. It accomplishes the dual purpose of physical warm-up and ensemble bonding before the group moves into more demanding scene work or game play.
Select the leader carefully for the first round. A confident, physically committed player sets the tone for the group. After the first round, rotate the leader role so that every participant practices taking initiative and commanding the group's attention.
Coach the group to match the leader's commitment level exactly. If the leader whispers, the group whispers. If the leader screams, the group screams. The exercise fails when participants hold back or perform the movements halfway.
Common coaching notes include encouraging the leader to make eye contact with the group, to vary the pace and intensity of the movements, and to trust that the group will follow even into absurd territory. Remind the leader that the exercise is not a comedy performance for the group but a shared physical experience.
A frequent failure mode occurs when the leader runs out of ideas and reverts to safe, conventional exercises. Side-coach the leader to take risks, to let the movements evolve organically, and to draw from unexpected physical vocabulary rather than defaulting to standard fitness moves.
For groups with physical limitations, adapt the exercise to seated or low-impact movements. The pedagogical value lies in the commitment and ensemble connection, not in athletic ability.

Related Exercises
Barney
Barney is an energy and movement warm-up exercise in which players adopt an exaggerated, lumbering physical character and interact with the group through simple, playful commands. The exercise asks participants to embody a large, slow, friendly creature (often described as a dinosaur or monster) and move through the space with maximum physical commitment and minimum self-consciousness. The inherent silliness of the character lowers inhibitions quickly, making Barney effective as an early warm-up for groups that are new to physical work or uncomfortable with large physical choices. The exercise builds comfort with exaggerated movement, vocal projection, and the willingness to look ridiculous in front of others, all foundational skills for improv performance.
Run Around
Run Around is a physical warm-up exercise in which players move through the space and respond to commands called by the facilitator. The exercise builds spatial awareness, group attentiveness, and physical readiness by requiring participants to shift direction, speed, or movement quality on cue.
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.
Bobsledding Bodies
Bobsledding Bodies is a physical warm-up exercise in which players form a tight line and navigate the space together, shifting direction and speed as a unit. The exercise builds group awareness, physical coordination, and the ability to respond as an ensemble to subtle changes in momentum.
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.
Stretching
Stretching is a physical warm-up practice in which performers release tension and increase range of motion through guided or self-directed body movement before a rehearsal or performance. The practice grounds players in their bodies, signals the transition from everyday life into creative readiness, and reduces the risk of physical strain during exercises that involve movement, physicality, or sustained ensemble work.
