What you can do from the watch

  • Log each set: adjust reps and weight and mark it as done.
  • Control rest with a countdown between sets.
  • Log meals and supplements without taking out your phone.

What to look for when choosing an app

  • That it has its own watch app, not just notifications from the iPhone.
  • That logging a set is quick: few taps, with the crown or by touch.
  • That rest times itself and you can skip or extend it.
  • That it works well with the iPhone, where you can calmly see your history and progress.
  • What it requires: the watchOS version and whether it needs the iPhone nearby.

How FierFit Gym does it

FierFit has its own Apple Watch app. You adjust reps and weight by turning the Digital Crown or tapping (voice dictation for sets is Premium), control rest with a countdown, and can log meals and supplements from the watch. There are also watch-face complications.

It requires FierFit on your iPhone and watchOS 10 or later.

Tips for training with the watch

  • Prepare your routine on the iPhone before you walk into the gym.
  • Let the watch handle rest and use that time to breathe and drink water.
  • Check your progress on the iPhone afterwards, on a bigger screen.
