Start small and work up.
I was 55lbs over weight this time last year. I was fed up with the way I looked, and the way I felt. I was tired a lot, and couldn't sleep right to save my life.
I started running. I am 28years old mind you but a full time job working nights, spending most of my time behind the wheel of a car did NOT do wonders for my physical conditioning.
I started a half a mile at a time, and just increased the mileage. I run 15 miles a week now, and work out lifting weights monday-thursday.
I am down to a solid 200lbs, and feel like I used to in High School. Except I like running now way more than I ever did back then.
I don't think that you need to do my routine, but small changes like getting out from in front of the TV and riding a bicycle is a great way to get started. Making small changes like taking the stairs instead of using the elevator. I realized that I had allowed my sedimentary life style to ruin any sort of physical fitness I used to have. I started to be conscious of the foods I ate. Making choices like avoiding fast food joints and eating at home made a huge difference in how I felt. Fast food really takes the energy out of me now when I eat it. The amount of crap in fast food is just ridiculous these days. It also amazed me just how much money I saved from eating at home compared to out. All the money I saved now goes to the ammo fund
. Small changes such as drinking sodas vs water. It took me a month of solid cravings before I could quit drinking sodas and just drink water. Thank goodness for Ice Tea! Now I strictly drink water, and avoid sodas like the plague. I haven't gotten rid of my beer taste though.
Small changes in diet and behavior will go a long way to your personal well being. You are seeing the results of your past behavior. Now you just need to set some goals for yourself in the near future to attain. IE: Getting to your truck without breaking a sweat. Try walking around your neighborhood for 15 minutes a day everyday. See how that works out. Try upping your distance later. Keep your mileage comfortable for you.
Commit your self to attaining your goals and you will see a difference. It just takes the first step to getting there. Once you see the results of your labor its addicting.
