Might I suggest you begin a workout regimen, IF you currently do not. You could join a local health club for a trial period before possibly buying some equipment for home use ?? If you are social, the club setting may work better and extend your circle of friends. I prefer home workouts- do it anytime of day/night, catch up on ESPN, etc. You could become a runner- requires no real investment, can do it almost anytime, etc. I ran almost daily for nearly 20 years, even living in the Midwest. You start easy and work up...it takes little time and is an excellent stress reliever. Your endorphin's surge and you feel great afterward.Recent research indicates that only a few minutes of cardio per day provide good protection.
Like you, my brother is self-employed and begins his day early enough to sneak in a quick elliptical workout and work on a ball for his bad back.It helps him relieve stress, keeps him in pretty good physical shape (thus extending his working life) and it helps him qualitatively pass the time, since he is single. He works until late in the evening writing reports so early morning workouts are necessary, before he is off to his first job.
For those of you who are "antsy" when not working every second, you might give this a try in the new year. It helps you burn off extra energy, is healthful for mind/body and a productive use of your time. I have adopted a workout regimen daily over the last 34 years and it has helped me immensely. In my former job, I had to take required physicals every six months and maintaining good health was critical to remaining employed.
Best wishes.Give it a try- you have everything to gain and pounds to lose...
