What respiratory systems do you use when weight lifting?

Answer 1

if you do a lot of running and cardio work then you have a healthy heart leading to a healthy respiratory system. but if you lift weights and hold your breathe during your repetitions then it is bad for you because your heart keeps pumping but you don't breathe and you keep harmful toxins inside your body. Not a big deal but still something to think about. make sure you inhale and exhale when your lifting, whether it is heavy or light.
