How it works
Weight = BMI × height(m)² for a low healthy BMI band
Endurance athletes tend to perform near the lower end of the healthy BMI range. This gives a sensible target band from height — a guide, not a prescription, since bone and muscle vary.
Worked example
At 175 cm (male), a BMI 20–22 band is roughly 61–67 kg.
Frequently asked questions
Should I really race at the low end?
Only if you can reach it healthily while fuelling well. Under-fuelling to hit a number hurts performance and health.
Does muscle change this?
Yes — very muscular athletes may sit above the band and still be lean. Treat it as a starting reference.
