Is it possible to train your internal organs?
Cardio is a workout for your heart
HGH x F
liver growth: alcohol (10am x 7 days a week)
brain growth: putting your head in a microwave (5x5)
lymph growth: any infection will do.
and other organs, hgh + insulin
i don't know man, get on a cycle and thicken your blood to see if strain on your heart makes it stronger
