I get asked all the time how I stay motivated to exercise. I tell people that it's not about motivation - it's about commitment. I compare it to work. I have a great job. I am well paid and work in a comfortable office with lots of freedom to do my own thing. Not to mention great benefits and a fantastic boss. BUT - I HATE getting up in the morning to go to work. I am NEVER motivated to go to work. If I won the lottery, I would be out of here in a New York minute. So I am not motivated to go to work, I am COMMITTED to go to work. Why? Because there is no other choice! I can't just decide to not get up and go to work in the mornings. I look at exercise the same way. I don't give myself an option. I work out during my lunch hour because I HAVE to.
There is, believe it or not, a certain freedom in this. When you have a choice taken away from you and you just do it. I have never gotten back from a run and thought "Damn, I wish I had never run and burned 500 calories today." Nope. I always feel great afterwards. Or lifting weights - sometimes I hate lifting weights. But afterwards, when my arms or legs are exhausted, I know that muscle is building. And when I see myself in a sleeveless shirt and can see real muscle definition even with the loose skin - damn, that looks good!
Maybe someday I'll be the person that itches to go out for a run and get all sweaty and tired or can't wait to get my hands on weights and lift. I'm not that person today, but I am a COMMITTED person.
Don't wait for your mind to give you the ok. Our minds tend to talk us out of things, not into them. Just do it! I know it sucks. Eating right and exercising is HARD. Being fat is HARD. Choose your HARD.
