...but I actually enjoy my workouts - the days I don't work out, I just feel blaaaah.
I haven't always been an exercise nut - gym rat- whatever you want to call me!
I've said this before but it's important to find an exercise that you ENJOY doing, preferably two exercises - a 'cardio' type of exercise and a 'sport' type of exercise (for instance, I enjoy the Precor EFX for cardio, and bicycling for 'sport'). And don't forget weight training - it's easy to get started and there are a lot of books and resources out there with easy to follow routines - I would recommend Joyce Vedral's books right off the bat.
If you don't feel comfortable enough exercising in public (fears of being in an exercise class with a lot of very slender women!) I highly recommend finding an exercise class especially geared towards larger-sized women (and men!). At 265 there was
no way I was going to go into a 'normal' aerobics class - luckily Kaiser Permanente had a "Great Shape" movement class that helped me to rediscover my body!
A terrific book to read if you're fat and haven't really exercised in awhile (or want to learn more) is titled "Great Shape: The First Fitness Guide for Large Women" by Pat Lyons and Debby Burgard. It doesn't focus on weight loss, but on living an active lifestyle regardless of your weight.
I've also mentioned Jazzercise frequently. You can get a coupon for a free Jazzercise class at their website -
www.Jazzercise.com - what do you have to lose? It's great fun!
If you're going to purchase accessories to motivate you to get moving, I suggest two 'musts' - a heart rate monitor and a portable CD or tape player! Burn your own CDs or make some tapes with the kind of music that will keep you moving and motivated. Or try "books on tape" if you like to read while you work out (most people's workout intensity goes wayyy down if they're working out while reading).
Set an exercise goal - my goal last year was to do a metric century and climb Half Dome in Yosemite - I did two metric centuries (62 miles each) and didn't get to the top of Half Dome BUT we did make it to the shoulder before acrophobia set in on my part!

There are lots of exercise-related events for charity - runs, bike rides (from 11 miles to 600+ miles in length!), etc. Jazzercise does lots of "Workouts for Charity" each year, and I'm sure they aren't the only ones who do so!
Whoops, going on too long again - have to start dinner...
