Group Exercise Program Design and Class Planning
What to know
Start with a needs analysis. Who is in the room (age, fitness, injuries, experience), what equipment and space exist, and how long the class runs. Every class needs a warm-up, conditioning phase, and cool-down.
Phase structure. Warm-up 5–10 min: dynamic mobility, rehearsal of patterns, gradually rising HR. Conditioning: the FITT-driven main block. Cool-down 5–10 min: gradual intensity reduction followed by static flexibility for the muscles worked.
Progression and sequencing. Apply the SAID principle and progressive overload through frequency, intensity, time, or complexity - one variable at a time. Order large muscle groups and multi-joint movements before small-muscle isolation, and high-skill work before fatigue accumulates. Balance push/pull and agonist/antagonist, and include core work; add balance and neuromotor components for older adults.
Music and choreography. Choreography typically builds in 32-count phrases. Match cadence to the skill level of the group rather than using tempo to create intensity, and plan transitions so participants are never left standing.
Modifications and environment. Offer a progression and a regression for every major movement (less range, less impact, less complexity). Plan for adequate unobstructed space, clear sightlines, safe flooring, and a backup plan for equipment failure or unexpected attendance.
Traps
- Putting long static stretches in the warm-up before the conditioning phase.
- Prescribing HIIT-style work to deconditioned beginners.
- Skipping the cool-down when class time runs short.
- Including contraindicated movements such as loaded spinal flexion with rotation or ballistic stretching.
Rule of thumb
Budget a 60-minute class as roughly 10 minutes warm-up, 40 minutes conditioning, 10 minutes cool-down - roughly 10–20% of total time for warm-up and about 10% for cool-down.
