The exercise library

Mettle’s development build includes a curated exercise library. 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 becoming the default in your plan.

• 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.
