Why workout content lives or dies on the cut
Fitness Reels and TikToks have one of the highest skip rates on short-form. Two things cause it more than anything else: form clips that drag past the point, and transitions that fall off the music. Cutflux is built for both.
Drag-past-point clips
A push-up shown for 8 seconds is 6 seconds longer than the viewer needs. Beat-locked cuts force you to a 1- or 2-beat pace, automatically tight.
Off-beat transitions
Cuts drifting 80–200ms off the kick make a HIIT routine feel sluggish even at 150 BPM. Onset-locked cuts feel snappy because they land on the actual hit.
Rep without reward
Showing reps with no visual payoff (no slow-mo on the hardest one, no speed ramp on the count) flattens the energy. Tempo-locked ramps fix this without breaking sync.
5 steps from gym to Reels
Drop clips
Drag raw footage in. Each exercise as its own clip works best; one continuous take also fine.
Drop the track
128–150 BPM for HIIT. Cutflux runs onset detection locally, no upload.
Snap to beat
Every exercise transition moves to the nearest kick or snare.
Add a ramp
For the climax rep, tempo-locked speed ramp slows the eccentric, snaps on the next downbeat.

The 3 mistakes that kill fitness Reels retention
1. Wrong BPM for the format
Strength training at 150 BPM feels chaotic. HIIT at 90 BPM feels slow. Match the BPM to the perceived intensity of the content.
2. Transition lag on the hook
If your first cut is 200ms off the first kick, retention drops 10–15% before second 2. Snap-to-beat fixes this automatically.
3. No payoff shot
Workout videos that end on a generic outro lose the loop. End on the final-rep shot, viewers loop to watch the form again.
