What Is a Stretch Timer?
A stretch timer is an interval timer that alternates between a hold phase and a short rest, repeating for a set number of reps. The point is simple: you stop watching the clock and start focusing on the muscle. Static stretching research consistently shows that 15–30 seconds is the effective minimum for a hold, and most people under-time their stretches without a dedicated tool keeping count. This timer handles the counting so you can close your eyes and actually breathe into the stretch.
Physiotherapy Hold Timing — Why 30 Seconds?
Physiotherapy protocols typically prescribe 30-second holds with 15 seconds of rest between repetitions. The 30-second threshold is where most research places the minimum effective duration for increasing muscle length through viscoelastic deformation — shorter holds produce a stretch reflex response without lasting change. The Physio Hold preset here uses exactly that timing: 30 seconds on, 15 seconds off, six reps. If you're working a post-injury rehab programme or following a physiotherapist's instructions, select Physio Hold and the timer will match your prescribed protocol. For general flexibility work, the Standard Hold preset (30s hold, 10s rest, 8 reps) is a solid default.
How to Use This Stretch Timer
Select a preset, adjust if you need a different hold duration or rep count, and hit Start. Audio cues fire at every transition — hold to rest and rest to hold — so you can keep your eyes closed and maintain position. The sequence runs through all your reps and stops cleanly at the end. If you're mid-session and need to pause, the spacebar or pause button holds your place.
