I like to exercise after smoking. It's never made it difficult for the activity I choose. I just throw on my MP3 player and do whatever it is I want to do. Just make sure you've been drinking a lot of fluid as well as have some on hand. Because smoking then exercising makes dry mouth about 5 times worse then smoking or exercise by itself. At least that's what I've experienced. After hydrating and getting rid of the initial dry mouth, it's all relaxing again.
