I was a competitive 400 runner in high school when I fell in love with the gym. However, I have yo-yoed my way in and out of workout routines ever since. I never made as much progress as I wanted to as either my workouts or my diet would take a nose dive. But each time I learned more and more, and was more successful each time as a result. At age 29 I still weighed under 130... It was rough... I made a promise to myself that I would only give myself one more chance. I was either going to pass the 150 lb mark (which was CRAZY since I had never cleared 132) that I would never allow myself to step foot in the gym again. I simply could not waste my time failing and restarting again and again, I had been doing that from age 16-29... and it ended.
It's a control thing. Any time my life spun out of control I found myself being pulled back into the gym. The results are controlable. If I succeeded it was because I worked hard; if I took a step back it was a direct result of MY failure to do something. Where else can you get that? Where else can your efforts ALWAYS be rewarded and your failures never go unnoticed?
