Workout flow

Routine, player, log, result.

SoundsFit is organized around the path from planning to training to review, so a workout does not have to scatter across separate apps or unfinished notes.

Build once, then start from the routine that fits today.

Create custom routines, adjust sets and rest, add notes or exercise images, use guided templates, and keep quick starts available for unplanned sessions.

Routine Player

Move through Set → Rest without rebuilding the session in your head.

The player keeps timers, goals, progress, skip controls, and music controls in the same workout surface so the next set is always clear.

Results

Finish with a log that is ready to review or sync.

Record weight, reps, duration, assist, rating, and notes, then review targets, actuals, session time, per-exercise cards, and Google Sheets sync status.

Training with music

Playback is part of the routine, not a detour.

SoundsFit can keep music choices attached to the workout structure: sets, rests, blocks, whole routines, playlists, local audio, and SoundsFit DJ surfaces all stay near the player.

Assign Apple Music, Spotify, YouTube, or local audio files to sets, rests, routine blocks, or whole routines so training and playback stay in the same flow.
