  2. Start the workout on your Apple Watch or iPhone.
  3. Start set, Complete set, and the rest timer starts, counting down from your planned rest.
  4. Finish the workout: your sets, Total rest and volume are on your iPhone, week by week.

Questions

Can I log a strength workout on Apple Watch?

Yes. Your plan’s workout runs on the watch set by set: Start set, Complete set, and the rest timer starts. The next Start set ends the rest.

Does the rest timer start on its own?

It starts when you tap Complete set. It counts down from the rest your plan sets, or up if it sets none, and carries on past zero (+0:12) so you see how long you really rested. Each rest is kept with its set, and Total rest adds them up.

Can I log sets by time as well as reps?

Yes. Each exercise is measured by sets and reps, or by sets and seconds for holds, with an optional rest between sets.

Does Treblew show how to do an exercise?

Yes, for 129 common exercises: an illustration of the movement with the muscles it works, and four to seven steps taken from the sources each entry names. It’s general guidance, not medical advice.

Is it free?

Workouts on iPhone are free, with one plan at a time on the Free plan. Running your plan’s workout on Apple Watch is part of Treblew Pro, and the Free plan includes one try.
