I'm a commuter and just plain pooped!

Wow! Thanks for all the replies and encouragement. I do go to the gym on Saturday for an 8:15 spin class followed by weights. I also usually take a nice hour long walk on Sunday with my neighbor and his dog. And on my lunch hours I try to take a walk depending the weather. Taking the stairs is out. They are strict on security and only used for fire drills.

Some of my co-workers do work-out at lunch but the thought of quickly exercising of 30 mins and taking a 2nd shower doesn't appeal to me. The same with lugging extra clothes to work.

I used to go to the gym 5 days a week before work when I didn't have this commute. I think menopause is the big issue. My metabolism just isn't the same anymore.
