I've haven't trained regularly in some time and want to start getting back into shape. Had a quick physical before joining a gym and they said that my oxygen intake is really low. I'm a smoker and I know that is a huge part of the problem. Basically stopped the cigarettes, just the occasional one plus weekly cigar and pipe smokes.
Is there any training I should start with to increase my oxygen intake before doing anything else?
