Re: Any ex-smoker CFers out there?
I must second Robert's feelings. CF cured me after 17 years. I listened to Coach's advice about getting the mechanics of the exercises, then increasing my consistency, al the while getting stronger and seeing effects of doing CF, when I finally began to work on intensity, within two days I knew there was no way I'd ever do a CF workout as Rx'd with any chance without quiting. I put it down almost 2 years ago.
Think of yourself and be selfish. If you don't want to die, if you think you're worth it, if you want to continue seeing the effects of all the work you're doing in CrossFitting, why smoke?
