Muscles

The skeletal muscles that move you and that you can build and keep with training and protein.

Muscle is the system that responds most reliably to deliberate effort: resistance training tells muscle to adapt, and adequate protein gives it the material to do so. Both are trackable. You can log strength sessions and their progression, and you can log protein against a target worked out from your body weight.

Muscle matters beyond the gym. It is metabolically active, it protects against falls and frailty with age, and it is the tissue a sensible weight-loss plan tries hardest to keep. Protecting it is mostly about two things you can see in your own data: enough protein and enough resistance work.

The mechanism that builds it is progressive overload — gradually asking the muscle to do a little more than last time, then recovering. That is exactly the kind of thing a log is good at holding: the sets, the reps and the load, week over week, so that "a little more" is a record rather than a guess.

Metrics that relate to muscles

• Strength workouts and progression
• Protein intake vs target
• Body weight and composition trend
• Active minutes

Calculators and reference pages that apply

Each of these is a real page on this site, chosen because it relates to this system:

The everyday levers

• Resistance training two or more times a week.
• Protein spread across the day toward a body-weight target.
• Enough total energy and sleep to recover.

What tracking can and cannot tell you

You can track training and protein, which is most of what builds muscle. A tracker cannot measure muscle directly, so treat strength progress and how clothes fit as the real feedback.
