The exercise library

Mettle ships with 263 curated exercises. Each is tiered as core, common, or novelty, which is why traditional staple lifts lead your program and unusual variations stay available as a swap rather than being prescribed at you.

• Instructions and form cues for each movement.
• Animated demonstrations for nearly all of them, bundled offline at around eleven megabytes and aware of Reduce Motion.
• Full search, and indexing into Spotlight so you can find a lift from the Home Screen.
