We just got a treadmill from Sears. Not the most expensive one on the market but it'll hold my 260 frame easily.
Lift weight, do cardio 2 times a week. Do abs, this helps more than you think. Watch what you eat. Don't starve yourself, you can go on a 2000 cal diet and if you are still starving, eat celery or carrots or some other fruit or veggie.
Cut out coffee. But I have read that if you drink 1 cup, thats 1 measuring cup, of black coffee, no sugar, flavoring, creamer, etc, before you workout that it actually jump starts to metabolic process and give you a small energy boost to get going.
Don't buy those diet pills, 99.9% of them are crap. I've tried a bunch of them for reviews online. The only one I saw benefits from was a ECA stack. But even then that is not reccommended for beginners or even average lifters/ workaholics. Trust me, its not fun.
If you have limited time, I reccommend you do cardio for 30-45 minutes, maybe 1 hour 2-3 times a week. For lifting, lift 2-3 times a week. If you can get your hands on some free weights, a bar, and a good rubber mat, do olympic lifts. Snatch and clean & press. These end up being nearly complete body workouts and will help you gain flexibility and stamina. Which helps in other parts of your life
But if you have time to kill and want a structured workout to help you say lose 30 pounds of fat and turn it into 15 pounds of muscle, then go to a board like bodybuildingforyou.com and ask around there for workouts. You can use the search feature and probably find it without even asking. People are on there all the time uploading workout schedules and making public posts about what their workouts are doing for them.
