Zone 2 Cardio
Zone 2 cardio is easy conversational aerobic work that builds your aerobic base; most training weeks need more easy minutes than hard intervals.
Zone 2 cardio is easy aerobic training where you could hold a conversation—often roughly sixty to seventy percent of max heart rate, though personal zones vary. It builds mitochondrial density, fat oxidation, and aerobic base without the joint stress that back-to-back hard intervals can add.
Most weeks need more easy volume than hard days; one long Zone 2 session plus shorter walks often beats cramming all aerobic work into one weekend day. Use a heart rate strap or talk test and keep pace modest on tired legs.
Common questions
-
How long should a Zone 2 session be?
Forty-five to ninety minutes is common for base building; beginners can start with twenty to thirty. Frequency—three to four easy days weekly—matters more than one long session.
-
What if your heart rate runs high on easy days?
Heat, caffeine, stress, and poor sleep raise heart rate. Slow down, shorten the session, or walk hills until talk-test pace feels truly easy.
