Did the tempo this morning had a nice warmup and a good 2 mile tempo followed by a cool down. Even tho I ran in the morning it was still hot☀️
Q: Why do capillaries increase with exercise?
A: By exercising muscles they grow more blood vessels by expanding the network of capillaries. Muscle cells boost levels of the enzymes that allow them to use oxygen to generate energy.
