Heart Rate Zone Calculations
Zone
% of Maximum Heart
Rate
Perceived Exertion
Benefits
1
50–60%
Relaxed, easy pace, rhythmic breathing
Beginning-level aerobic training,
reduces stress
2
60–70%
Comfortable pace, slightly deeper
breathing, conversation possible
Basic cardiovascular training, good
recovery pace
3
70–80%
Moderate pace, more difficult to hold
conversation
Improved aerobic capacity, optimal
cardiovascular training
4
80–90%
Fast pace and a bit uncomfortable,
breathing forceful
Improved anaerobic capacity and
threshold, improved speed
5
90–100%
Sprinting pace, unsustainable for long
period of time, labored breathing
Anaerobic and muscular endurance,
increased power
