Slowly step back out.
I bought a peddle bike and found I couldn't even make the trip 5 miles to a gas station for air in the tires. I have taken karate and paced myself but I tend to push to hard and over do. I went back to playing adult soccer ( both indoors and out) Softball leagues would be a nice way of getting back into things as well. Thing with the leagues... so many I see use the game as a reason to share a case of beer after. Golf, bowling, a ref., a walk in the park, swiming at the Y or on the beach. A pulled muscle from getting back into things fast or a heart attack.... watch and think of the risks and get back in slowly. Be mindful of what happens when that last out has the winning team go for the coolers. 19th hole, or just a stop at a local as a group. When we look ahead we can better prepare and stay on track with our recovery as we remain sober.
