So back in 2009, at age 17 weight 120, i used to run for 15 minute straight. And after that i have stopped running until recently. Now i cannot manage to run for one minute without feeling chest pain short of breath, and legs pain.. i weight 165 now. I don't smoke cigarettes, i only vape for the past 2 years if that matters. So my question is what can i do to get back into running? I am willing to do anything that's possible to get back.
