Any fitness program is better than no fitness program. It’s really not rocket science or magic: eat fewer calories and exercise more. I suggest teaming up with a friend for workouts, that way you can motivate your partner when they’re sore and want to take a night off/quit and they can do the same for you. It creates a virtuous cycle. The other thing to consider is to make lifestyle choices instead of short periods of physical activity/dieting and then slipping back into old habits.
If this looks like something you can see yourself doing regularly 5 years from now, then it might be a good choice. Personally I’ve lost about 25 lbs since November by cutting way back on takeout/eating out, cooking a lot more, and riding a stationary bike (going up from 55 minutes/day to 60 minutes/day tonight). I started out slowly (like 20 minutes) and added more time each week.
One tip for cooking is to make a big pot of something on Sunday night, portion it into separate containers to freeze/refridgerate, and then you can have fast meals during the week. One dish I’ve been making regularly is stuffed peppers. You can make a nice pot of brown rice, lean ground beef/turkey, Onions, Garlic, chopped mushrooms, crushed tomatoes, and other goodies (e.g.sun dried tomatoes add a lot of flavor). Then you can easily cut and roast the peppers each night, adding your pre-made stuffing and topping with a light sprinkle of cheese, and you’ve got a great-tasting, healthy dinner that you can put together faster than a trip to the local pizza shop.
