You picked a great time to start exercising. The spring, summer and fall allows you to take your exercise outdoors which is not only better but is also free!
The components of an exercise program should include some form of cardio, resistance training, core training, and stretching. Cardio could be walking, jogging, biking, an exercise class, playing certain sports, etc. It really doesn't matter what you choose. Just find what you like! Resistance training can be simply using tubing and would be a very effective workout. Basic crunches are a great beginner core training workout. A great time for core training and stretching is after a cardio workout when your muscles are warm and pliable.
Other low cost options can be joining a gym, purchasing used equipment online or at garage sales, borrowing DVD's from your local library, visiting motivational and "how-to" websites, or purchasing some inexpensive home equipment such as exercise tubing, a medicine ball, weighted bars, a stability ball, hand weights. You don't need to purchase all of these pieces. You can start a great exercise regimen with just exercising tubing.
