Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
A faster start
Getting set up is quicker and clearer. Answer a few short questions and
see a real training week built around your goal, your schedule, and the
equipment you actually have.
Training that fits your gear
Tell us what you own and your workouts will use it, so you stop getting
moves that call for machines you do not have.
Better workouts
Total body sessions now work more of your body in every movement. Warm
ups and cool downs are more reliable, better matched to the session ahead,
and more varied over time. Exercise selection is cleaner across the board,
so the moves you get are the moves you expect.
Audio coaching you can rely on
Your cues arrive when they should, including the halfway call. Your music
stays at full volume between cues and comes back properly once a cue ends.
Apple Watch
A new Recovery Compass complication puts your readiness on your watch
face. Recovery detail is easier to read at a glance and updates as soon as
new sleep and heart rate data arrives. The watch app is also steadier in
the background.
Saved workouts
Your saved workouts are now one tap from the main screen, with clearer
names and simple options to edit, duplicate, or delete.
Smoother account handling
Signing in, restoring purchases, and managing your subscription are all
more reliable, with clearer messages when something needs your attention.
Plus a long list of stability and performance improvements throughout the
app.
