Design the class across these six sections:

1. Class Structure & Energy Arc
Design the overall class flow following the proven energy arc model. Map the class intensity across time: opening and warm-up for the first 10 percent of class time at low to moderate intensity establishing the rhythm and community connection, progressive build during 10 to 30 percent building intensity and introducing the primary movement patterns, peak work block 1 during 30 to 50 percent at the highest sustained intensity of the class, active recovery or transition during 50 to 60 percent allowing partial recovery before the second peak, peak work block 2 during 60 to 80 percent matching or slightly below the first peak intensity, cooldown and stretch during 80 to 95 percent gradually reducing intensity, and the closing and intention during the final 5 percent bringing the group together. Provide the BPM or beats per minute guide for each phase: warm-up at 120 to 128 BPM, building phase at 128 to 135 BPM, peak blocks at 135 to 150 BPM or higher for high-energy formats, and cooldown at 100 to 120 BPM decreasing to 80 to 100 BPM for stretching. Include a song-count structure showing how many tracks fit each phase based on class duration.

2. Exercise Selection & Choreography
Provide the complete exercise library for the class with detailed descriptions. For each block, list the exercises in sequence with repetitions or time, tempo relative to the music beat, and movement transitions between exercises. Include choreography notes for music-driven formats: which counts initiate each movement, where to add arm variations, and how to layer complexity by teaching the basic pattern first and then adding coordination challenges. For circuit-based formats, design 4 to 6 stations with 3 exercises each, specifying work and rest times and rotation protocols. Provide an exercise complexity scale from 1 to 3: level 1 as the base movement that everyone performs, level 2 as the added intensity or coordination challenge, and level 3 as the advanced option for experienced participants. Include partner and group interaction exercises for community building: partner high-fives between sets, synchronized group movements, and competitive relay-style challenges. Design at least 2 signature moves or combinations that make this class format distinctive and memorable.

3. Scaling & Modification System
Create a comprehensive modification system that keeps all participants challenged and safe. For each exercise in the class, provide 3 versions: the low-impact or beginner modification that removes jumping and reduces range of motion, the standard version as the primary movement target, and the advanced progression that adds load, speed, plyometrics, or complexity. Design a visual cueing system so the instructor can demonstrate modifications efficiently: verbally cue the standard version, point to a designated participant or screen showing the modification, and briefly demonstrate the progression. Address common participant challenges: deconditioned beginners who need frequent rest breaks with guidance on active rest positions, participants with knee issues providing non-lunge and non-jump alternatives, pregnant participants with modifications covered in a pre-class check, and older adults with balance and impact considerations. Create a pre-class screening protocol: a quick 2-question verbal check asking about injuries and experience level that takes under 30 seconds per participant.

4. Cueing & Coaching Techniques
Provide the verbal and visual cueing system that drives an excellent class experience. Cover the 4 types of cues and when to use each: directional cues telling participants what to do next such as stepping right in 4 counts, motivational cues providing energy and encouragement such as acknowledging that participants are halfway through, alignment cues correcting form with brief technique reminders such as keeping the chest proud and the core braced, and educational cues explaining why a movement matters such as noting that this lights up the glutes. Provide a cueing timeline: pre-cue the next movement 4 to 8 counts before the transition, count down the final repetitions of the current movement, name the new movement clearly, then layer in form cues once the transition is complete. Include vocal technique guidance: projection without yelling, using microphone technique if amplified, varying tone and volume to match the class energy, and strategic use of silence for intensity during peak blocks. Provide 20 motivational phrases that go beyond generic cheerleading: connect to effort rather than appearance, acknowledge the challenge without minimizing it, and create moments of shared accomplishment.

5. Music Programming & Playlist Design
Design the musical foundation for the class. Provide a track-by-track playlist structure with BPM targets, energy level, and the exercise block each track supports. Include guidance on music licensing requirements for group fitness instructors: which platforms offer licensed music for fitness and the legal considerations of using personal playlists. Design 3 complete playlist outlines for the class format: a crowd-pleaser playlist with mainstream hits, a themed playlist built around a genre or decade, and a high-energy playlist for an advanced or competitive class. Cover the relationship between music tempo and exercise selection: high BPM tracks of 140-plus for cardio intervals, moderate BPM tracks of 120 to 135 for strength with controlled tempo, and low BPM tracks under 100 for stretching and recovery. Address how to handle song transitions: crossfading technique for seamless energy flow, using musical builds for intensity peaks, and timing exercise transitions to musical phrase changes every 32 counts. Include guidance on reading the room and adjusting energy through music volume and track selection.

6. Class Management & Participant Experience
Design the operational and experiential elements that elevate the class. Cover pre-class preparation: arriving 15 minutes early for equipment setup and room preparation, greeting participants by name, setting up equipment stations or demonstrating the layout, and performing a sound and music system check. Design the first-timer experience: introduce yourself and learn their name, position them in the middle of the room rather than the back, provide a brief orientation to the class format and the permission to take breaks, and check in with them at least once during class. Create a participant retention strategy: learn names within the first 3 visits, celebrate attendance milestones at 10, 25, and 50 classes, create a private social media group for class community, and host quarterly social events outside of class. Address common class management challenges: latecomers and the policy for safe integration, participants who consistently perform movements unsafely with one-on-one conversation strategies, managing romantic or personal dynamics within the group, and handling complaints or negative feedback constructively. Include a post-class debrief template for the instructor to self-assess energy, timing, cueing quality, and areas for improvement.

Disclaimer: Group fitness classes should be led by certified group fitness instructors. Participants should inform their instructor of any health conditions or injuries before class. This guide is for educational purposes.
