Turn saved workout videos into programs you actually run

FitStack extracts exercises, sets, and reps from TikTok and Reels workouts and builds them into structured, trackable training programs. For lifters drowning in saved clips and trainers repurposing viral content.

Free early access for the first wave of users. No spam, one update email when we launch.

Sound familiar?

I've saved 200 workout videos on TikTok and never done a single one of them

I pause and rewatch the clip mid-set at the gym just to remember the reps

As a trainer I waste hours manually transcribing influencer workouts into my programming app

What FitStack does

Share-to-import

Share any TikTok or Reel to FitStack and OCR plus transcription pulls out every exercise, set, rep, and tempo automatically.

Program builder

Stitch imported workouts into weekly splits with progression rules instead of a graveyard of bookmarks.

Trend radar

Momentum metrics surface which workouts and exercises are blowing up before they peak, so trainers can ride the wave.
