The smallest blood vessels in the body are your capillaries. They deliver oxygen and nutrients to your organs and muscles. Through exercise, your capillaries increase in number and size, which in turn, helps oxygenated blood reach areas it may have not gotten to before.
This increased and improved circulation:
- Reduces fatigue;
- Helps you heal from workouts faster;
- Helps build new lean muscle tissue;
- Boosts white blood cell production, keeping you healthier; and
- Helps your lymph nodes flush waste out of the body.
All of this helps to create a stronger immune system, which means less sick days!
