I used to think I did not have enough time to exercise, until I had a heart attack. Now I have enough time - interesting, don't you think?

For me it is lack of motivation. Go to the gym and work out for an hour or go home, sit on the couch and watch my favorite show? Sitting on the couch usually wins. I convince myself that I'll work out the next day, but every day something else seems to come up that I tell myself is more important than working out.

Prioritizing exercise is the issue for me. It's so easy to put all the other things in life in front of it. Having a small child and working a full time job makes it difficult for me to prioritize exercise. I feel guilty spending an hour exercising when that's time I could be with my daughter. I know, I know, healthy moms who take care of themselves are good moms...

I use my lunch hour to walk. I promised myself I'd walk at least 30 minutes 5 times a week. Usually its everyday, then if I miss a day, it doesn't matter so much. It does make me feel better.

Time is the real issue for me. I need to force myself to get up early and get it out of the way. It's the best way to start the day!

I am active, ALTHOUGH, motivation is important. Blue Points was fantanstic, kept me motivated. A girlfriend....keeps you motivated. Discounts, office contests, discounts, any thing to increase motivation.

My greatest barrier by FAR is working a desk job. I mean, one of the many requirements my job has is to sit behind my desk for 8 hours a day. That doesn't exactly promote physical activity. While I understand that it isn't my employers job to make sure I am physically active, they have to understand that healthy and fit employees are more productive and overall happier. You would think all employers and employees would be interested in getting more exercise in during the work day... especially if there were some sort of incentive like lower health insurance premiums for integrating a wellness program.

My greatest barrier to physical activity/fitness is fear of additional pain. I am a chronic pain patient and I am always scared that I will injure myself more and cause more pain. I know this is an irrational fear since I have worked out with very little additional pain but I am still very fearful. Sometimes the biggest hurdles to overcome is our own mind....

Exercise is not an option,since most of have very sedentary life styles. Fast food dominates our food choices and having self control is a day to day battle. With all of these things against us the best possible soultion or least to get on the right track is EXERCISE!

Not only does it help phyically but emotional well being is an added bonus!

I started exercising regularly a little over 2 years ago. I am over 50 and I promise it killed me at first. I was determined to lose weight and I knew that diet would not work alone at my age. When I first started walking on the treadmill I thought 3.5 MPH was FAST! And I tried running at 4.2 and I could barely run 30 seconds. Now I walk at 4.0 MPH and run at 5.5-5.8 MPH for 2 miles. It can be done. You have to be consistent and it takes a lot of determination. The bottom line was this..... I WANT TO LIVE!!!! That's motivation if nothing else is.

And one more thing.... I lost 55 pounds and have kept it off for 2 years.

My employer has an AMAZING gym in our building, but I do not have time during the work day nor am I able to stay after work hours to utilize it... it would be nice if they offered discounts to join a gym closer to home (i.e. YMCA). I feel penalized and am unable to exercise like I want too.

I am active, but I am still limited by pain.

I am active on the weekends, but it is hard when you have a desk job to be active during the week. I love my job, but it does limit me as far as exercise goes. I try to make up for it on the weekends and at night if I can.

"Physical Restrictions" really would have done well as one of the options above. I see that through many of the comments, and know that to be true in my own life. My mom says from the moment I could speak I would say "my head hurts". I remember having my first spinal xray at the age of 12 because of severe back pain. Arthritis is not fun, but the pain reduces upon maintaining a level of gentle activities. But I have to be very careful - it doesn't take much to induce a muscle spasm in my lower back and hips that distorts my frame enough that I can't stand straight. And THAT is no fun, not to mention, impossible to work out in!
