  • This app hasn’t received enough ratings or reviews to display an overview.

• Rename your workout and pick its icon in a new, dedicated settings screen — tap the workout's name at the top of the builder. • Background music now keeps playing at full volume during a workout. • Stopping a workout takes you back to its setup screen instead of all the way to the list. • Cleaner builder layout — structure and timing reordered for a smoother setup.
