Hormonal

The hepatic lipase (HL) promoter polymorphism (HL-514T allele) modulates the effect of physical activity on HDL-C levels, with carriers of the T allele showing a blunted response to exercise-induced HDL increases.

If you have certain genetic variants (HL-514T), you might not see as big a boost in 'good' cholesterol (HDL) from exercise as others. This doesn't mean exercise is useless, but it suggests you might need a more targeted approach to managing heart disease risk.
