90 second timer

A ninety second timer with a sound at the end. A minute and a half is the standard rest between working sets in strength training, which is the main reason people time it.

How it works

  1. Finish your set, tap Start, and rest until the tone.
  2. Ninety seconds is a common rest for moderate strength work. Heavy sets often want longer.
  3. Resting by the clock rather than by feel keeps sets consistent, which is the point.
  4. On your phone the timer keeps running in your pocket, so you do not have to watch it.

Frequently asked questions

How long should I rest between sets?
It depends on what you are training. Roughly: thirty to sixty seconds for higher-rep conditioning work, around ninety for moderate strength sets, and two to five minutes for heavy low-rep lifts where you need the recovery to hit the same weight again.
Why time the rest at all?
Because untimed rest drifts. It stretches when a set was hard and shrinks when you feel rushed, and then your sets are not comparable week to week. A fixed rest is one less variable.
Is ninety seconds the same as a minute and a half?
Yes, and you can set it either way. The one and a half minute phrasing is the same countdown; this page just uses the seconds people search for.
