Cardio Fitness Without All-or-Nothing
Build aerobic capacity through repeatable effort and recovery.
What to know
Moderate and vigorous activity are relative to the individual.
Conversation, perceived exertion, and clinical guidance can help set intensity.
Intervals can be adapted to many modes and abilities.

Questions to take into care
“Should I use heart-rate targets?”
“Do my medications change how exertion feels?”
Why this chapter matters
