A common formula is 220 minus your age, though this is an estimate with individual variation.
Typically zones range from light activity (50-60% max HR) through peak/anaerobic (90-100% max HR).
Often cited as the moderate zone (60-70% max HR), though total calories burned matters more than zone alone for fat loss.
Often the higher zones (70-85% max HR) are associated with cardiovascular fitness improvements.
It's a widely-used estimate, though individual maximum heart rate can vary - more precise methods exist but require testing.
