Endurance
Cardiovascular stamina is built in layers
Easy aerobic work, purposeful intervals, strength, and daily movement each have a place. The right mix depends on history, goals, climate, and the ability to recover between sessions.
Rather than chasing a single score, readers can look for steady breathing, repeatable pacing, and a gradual return to calm.

| Focused work | Explore controlled challenge | Is recovery planned afterward? |
| Strength | Support force and economy | Does technique remain stable? |
