Heart rate between sets

By · ORCID · LinkedIn · Updated

Short answer

Your heart rate rises a little after the effort and stays up for a while after it. Between sets it works as a readiness cue, not a timer: you watch the number fall and start when you are ready. Beatcast's rest coach does the watching for you.

Last checked: 21 October 2026.

What the number does

Heart rate lags effort. It climbs after a hard set has started and keeps going for a moment after it ends. Your breathing usually settles before your heart rate does. So the number in the minute after a set is the tail of the last effort, not a verdict on the next.

That is also why a single reading is a poor rule. Your own numbers vary from day to day, with sleep, heat and what you ate. Look at the direction, down and flattening, and ignore any one value.

We are not going to tell you what your heart rate should be between sets, or how long to rest. The sources give no single answer that fits everyone, and a made-up one would be worse than none.

What a strap adds

Between sets, you want a number now. A sensor on a strap or arm band sends about one reading a second, and the phone propped on the bench shows it without you touching it. A watch on a wrist that is gripping a bar is a harder place to read from, and we have no study to cite for what that does to the reading, so we leave it there.

The rest coach

Your lifting app counts sets and reps, and stays quiet about your heart rate. Beatcast runs alongside it.

  1. After a set, tap Start recovery. The floor sits beside it: the heart rate you rest down to. Tap it to change it.
  2. Beatcast times the rest and says when your heart rate reaches the floor.
  3. Or switch on Start recovery automatically, and it spots the drop after an effort by itself, whether that was a set, a climb or an interval.

A rest ends when your heart rate holds at the floor, or at the max rest you set. Each zone profile keeps its own rest coach settings, on its Alerts page.

The Lock Screen and the Dynamic Island keep the number in view while your other app is open, so there is no app swapping between sets. See the Lock Screen guide.

Setting it up

  1. Connect a sensor. See how to connect a Bluetooth heart rate monitor.
  2. Start a session in Beatcast, then switch to your lifting app.
  3. Check the floor on the zone profile's Alerts page. Each rest ends there.

Where Beatcast fits

This is the one place where a Beatcast feature is the answer. Most strength apps ignore heart rate, so Beatcast runs next to them. Beatcast on the App Store. Fourteen days free, then one purchase.

Questions

Should I wait for my heart rate to drop before the next set?

That is your call. We show the number and the trend. Rest advice belongs with a coach.

Does the rest coach work without a sensor?

No. A sensor is required.

Is a drop in heart rate a sign of recovery?

It is a sign your heart rate is lower. Beatcast says no more than that.
