The mix that holds your fitness class with no dead air
Zumba, Body Combat, cycling, HIIT, Pilates: build a seamless playlist so you never lose your students between two songs.
Quick overview
A fitness class with no music gaps is a class that holds. As a Zumba coach, Body Combat instructor or cycling lead, you know every silence breaks the effort. With MixClap, you build your playlist into a single file that flows with no dead air, respecting the BPM of each phase (warm-up, cardio, core, cool-down).

Group fitness: tempo, phases and playback
Sport psychologist Costas Karageorghis (Brunel University) reports a narrow preferred tempo range for background workout music: 125 to 140 BPM. Faster is not better. The mix keeps the cardio block inside that range and removes every gap between tracks.
Key figures
- Background workout music
- 125 to 140 BPM, according to Karageorghis
- Effect on perceived effort
- About 10% lower with background music
- Indoor cycling
- One pedal stroke per two beats: 80 rpm rides on 160 BPM music
- 45-minute class
- About 13 tracks of 3:30, fewer if you keep long songs
- Licensed programmes
- Music ships with the programme: a custom mix is for your freestyle classes
- Playing music in a gym
- Public playback needs a licence from the local collecting society (Sacem in France, PPL PRS in the UK), usually held by the venue
Example: a 45-minute cardio class
- 0 - 5 min
Warm-up
Build gradually towards 120 to 125 BPM with simple moves.
- 5 - 35 min
Cardio
Stay between 125 and 140 BPM, with short crossfades so the effort never drops.
- 35 - 40 min
Strength
Slower, steady tempo so you can count reps.
- 40 - 45 min
Cool-down
Drop below 100 BPM, long fades, stretching.
Common mistakes
Mixing up rpm and BPM
In indoor cycling, a 160 BPM track rides at 80 rpm (one stroke per two beats), not 160.
Pushing tempo forever
Above 140 BPM, background music is not rated any better according to Karageorghis. Vary intensity through the exercise, not just the tempo.
Leaving the outros in
A 40-second song ending lets the group drop off. Cut at the end of the last chorus.
Explicit lyrics
In a gym or a kids class, use the radio edits.
How to do it, step by step
- Step 1
List songs by phase
Warm-up (5 min) → cardio (30-40 min) → cool-down (5-10 min). Upload 8-15 songs depending on length.
- Step 2
Trim long sections
Keep the chorus and one verse, cut the long outros that drop the rhythm.
- Step 3
4-8s crossfades
To switch between songs without a gap: 4s in fast cardio, 8s in cool-down.
- Step 4
Export to 320 kbps MP3
Instant playback on phone, Bluetooth speaker or gym PA system.
Pro tips
Know the BPM of your tracks
Tools like Spotify or DJ apps display BPM. Aim for 130-140 in cardio, 90-110 in recovery.
Plan around choreo changes
If you change choreography on every song, keep crossfades short (3s) so you don't lose students.
Prep 2-3 mixes per session type
A cardio mix, a core mix, a cool-down mix — you keep control of intensity.
Test in class conditions
Run the mix once in rehearsal to verify pace and volume.

Frequently asked questions
How many songs for a 1-hour class?
Between 12 and 18 songs depending on whether you keep them whole or trim them.
Does MixClap work with a Bluetooth speaker?
Yes, the MP3 or WAV export plays on any audio system (phone, Bluetooth speaker, gym PA).
How do I manage BPM?
MixClap estimates BPM locally and displays it when detected. You can then order tracks, adjust a target tempo and choose sync for each transition. If analysis fails, enter or adjust the tempo manually and check the preview.
Can I edit my mix between two classes?
Yes, your project stays in your browser. You can edit it, add or remove songs and re-export.
