Tap a rest length, then Start. It beeps and vibrates (on phones) when the time is up and counts your sets. Keep this page open during the session - nothing to install.

How long should you rest between sets?

Longer than most people think. For heavy compound lifts - squats, deadlifts, bench, rows - 2 to 3 minutes lets you lift more total weight over the session, which is what builds strength and muscle. For lighter isolation work like curls, raises and machines, 60 to 90 seconds is plenty. If the goal is fitness or fat loss with circuits, 30–60 seconds keeps the heart rate up.

Why a timer helps

Without one, rests drift - short when you are keen, long when you are on your phone. Both hurt: too short and your fifth set is weaker than it should be, too long and a 45-minute session becomes 80. A timer keeps it honest and, as a bonus, counts your sets so you do not lose track between exercises.

Using this one in the gym

Pick the rest length, hit Start after each set, and put the phone down. It beeps and buzzes when it is time, tries to keep the screen awake while it is running, and changes the tab title so you notice even if you have switched apps. There is nothing to install and it does not need signal once the page has loaded. Save the page to your home screen and it opens like an app.

Not sure what weight to be lifting in those sets?

The one rep max calculator gives you training weights by percentage, and the plate calculator tells you what to put on the bar. For a full plan with sets, reps and rests already worked out for the week, that is what the coach does.

FAQs

How long should I rest between sets to build muscle?

About 2–3 minutes for big compound lifts and 60–90 seconds for smaller isolation exercises. Research shows longer rests on the heavy lifts lead to more muscle growth because you can do more quality work.

Is 60 seconds rest enough?

For isolation exercises and circuits, yes. For heavy squats, deadlifts or bench press it is usually too short - your later sets will suffer. Give the big lifts 2 minutes or more.

Does resting longer burn fewer calories?

Slightly, during the session, but it lets you lift heavier, which builds more muscle and raises what you burn all day. For fat loss, the calorie deficit from food matters far more than rest length.

Should beginners rest less?

No - if anything beginners benefit from full rests while they learn technique. Short rests are a tool for conditioning, not a rule for progress.
