WJR Trainer
WJR Trainer Support
WJR Trainer is a soccer conditioning timer for Walk, Jog, Run drills. The app uses large on-screen pace cues, color-coded backgrounds, and soccer-style whistle sounds to help coaches guide players through interval training.
How It Works
Players move between endlines, sidelines, cones, or marked field distances.
Each minute follows this pattern:
Walk: 0 to 29 seconds
Jog: 30 to 49 seconds
Run: 50 to 59 seconds
The timer can run continuously, or coaches can set an optional end timer to stop the drill automatically.
