Length
3 to 5 minute tracks, or full class mixes built from several generations at matching tempos.
Levels and loudness
Energetic masters work, but leave room for an instructor’s voice in class videos.
Licensing
Use in fitness videos and online classes is covered by paid plans. Live public performance in a gym may also need local performing-rights arrangements depending on your country. The full terms are on the licensing page.
A workflow that works
- Choose BPM by activity (for example 125 to 135 for steady cycling)
- Generate each interval track at the same key and tempo
- Mark peaks for intervals
- Sequence them into a class
Avoid long breakdowns in the middle of a set. They kill momentum.
Prompts for workouts
High-energy workout track at 128 BPM, driving house beat, build every 30 seconds for intervals
Hard gym phonk at 140 BPM, aggressive bass, no breakdowns
Cooldown track at 90 BPM, warm deep house, slow and steady
