How to use the stretch timer

  1. Pick a preset — or adjust Hold, Rest, and Rounds with the + / − buttons to match your routine.
  2. Turn on Switch Sides if you want the timer to automatically cue left and right — useful for hip flexors, hamstrings, and shoulder stretches.
  3. Press Start and ease into your first stretch. Keep sound on so you hear the beep when it's time to move.
  4. Breathe slowly throughout the hold — never push into pain. A gentle pull is all you need.

Common questions

How long should I hold a stretch?

Most research suggests holding a static stretch for 20–60 seconds is effective. For general flexibility, 30 seconds is a good starting point. Older adults often benefit from slightly longer holds of 45–60 seconds, as muscles take a little more time to relax into the stretch. Always stay within a comfortable range — you should feel a gentle pull, never sharp pain.

Is this interval timer free?

Yes — completely free, no sign-up or account required. You can use it directly in your browser on a phone, tablet, or computer. It runs entirely in your browser with no data sent to a server.

Can I use it for chair exercises?

Absolutely. The timer works well for any seated or standing stretching routine. Try the "Gentle" preset (30s hold, 10s rest, 6 rounds) for a calm chair-based mobility session, or mix in our printable chair exercises alongside the timer.

How many rounds should I do?

A typical gentle routine covers 4–8 rounds, which usually takes 6–12 minutes depending on hold and rest times. Beginners can start with 4 rounds and shorter holds. If you are working on a specific area — like hip flexors or shoulders — 6 rounds of the same stretch on each side gives a thorough session.
