I've always worked out and always will. I generally enjoy it although I have the odd day when I'm not in the mood. I've always put daily exercise before almost everything in my life, career etc.
I'm sober just over 100 days and I feel exercise gives me a mental boost for the rest of my day. I try to take at least one day a week off (sometimes don't/can't though) and never exercise when I go on holidays any more.
