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
