Captions for fitness video that actually count reps.

Fitness clips need timing-accurate captions: rep count, exercise name, form cues. SoCaptions' word-level timing makes 'Hold for 30 seconds' actually display for 30 seconds.

Why captions matter on Fitness & workout video

Fitness viewers can't unmute mid-rep, can't scrub mid-set, and need form cues at the moment they apply. Captions are functional, not decorative — they're how the workout is delivered.

Recommended style

Bold sans-serif with a thick stroke. Fitness viewers don't have time to read tiny text mid-rep. Solid background plate works well against gym backgrounds with mixed lighting.

The Fitness & workout video captioning playbook

  1. 01
    Cut the clip to one exercise
    Or one circuit. Don't cram a full 45-minute class into a 60-second clip.
  2. 02
    Generate captions
    Whisper picks up rep counts and exercise names cleanly. Hand-correct any niche movement names.
  3. 03
    Add visible rep / time cues
    If you say '30 seconds,' the caption should show '30s' for those 30 seconds — not flash and disappear after the spoken word.
  4. 04
    Export burned-in MP4
    Fitness viewers cross-post heavily; burned-in survives every cross-post.
Do
  • Use a solid background plate, not just a stroke. Gym lighting is mixed.
  • Position captions higher (45–55% from top) — phones on floor/mat angle them oddly.
  • Caption rep counts as text, not just speech. Visual count beats spoken count for muted feeds.
  • Slow down the speech if needed for caption duration. Reading time matters when viewers are mid-rep.
Don’t
  • Don't use thin fonts. Mixed gym lighting eats them.
  • Don't caption every breath. Caption form cues only.
  • Don't crop the form out of the frame to fit captions.
  • Don't ship without captions — fitness is one of the most muted-feed-watched categories.

Frequently asked

Should I caption every rep?+

No — caption form cues, exercise transitions, and rest-timer counts. Per-rep captions clutter the frame.

What font size for fitness videos?+

60–72px on a 1080-wide canvas. Larger than typical short-form because viewers may be 6–8 feet from their phone.

Can I caption a fitness video that's mostly music with no dialogue?+

Yes — caption the form cues you'd say live, even if you didn't record audio. Type them in directly.
