Welcome to Mettle

Most strength apps tell you what to lift. Mettle tells you why: because you topped the rep range, because you are four weeks from a deload, because your squat needs volume your bench does not.

It also meets you where you are. On day one the language is plain and reassuring. A year in, the same program gets described in the terms an experienced lifter actually wants. What changes is the explanation, never the quality of the plan underneath.

The four tabs

• Today: the session waiting for you, or a recovery card if you have earned one.
• Plan: the program, the training week, and the ability to edit any day.
• Coach: a conversation grounded in your own program and history.
• Progress: volume, duration, heart rate, tempo, records, and set-by-set history.
