1.
Start small - but do start and start everyday - even if it's 5 minutes a day. You will improve over time, give yourself that chance to keep improving - it's critical.
2.
Build slowly - chances are if you're overweight/obese, you're out of shape. Keep that in mind at all times. Too much too soon will more than likely result in stoppage or failure and in the worst case, injury or possibly death.
3.
Selection - It's pretty critical. You have limits and you also want something that keeps you interested. It's pretty easy to see why walking the is the standard choice, most everyone can do it and it's not too difficult to walk 5 minutes to start, virtually no expense and it can be done just about anytime. Walking is rarely boring (with music) and the progress to expand this exercise doesn't take long.
If you enjoy any exercise, you will do it more often - plain and simple.
4.
Don't be embarrassed - Even though you will be and yes, people will be watching. You have to set it aside. You will get the final laugh - eventually. You'll also be surprised that there will be a mutual respect after awhile, the thin people will eventually smile or nod and wave - not all, but you will become one of them in time. We're not there for their acceptance or approval however you will feed off of their acknowledgment and it can give you added drive to keep after it.
The embarrassment factor will turn full circle - I know, it's a hard one to swallow.
5.
Motivation - The desire to look better and feel better, add in the prolonging your life factor and you have a good recipe to get off your ass and do it. Again, if you enjoy it, the motivation rarely needs to be enticed. I wake up every day wanting to exercise on
my level. Results will enhance your motivation as well, just give it time.
