Fitness allows your heart to function with less strain placed upon it. Blood circulation gets better and better. We sleep better. Our appetite for food is more manageable and our digestive process works better. Greater flexibility and ease are seen in the joints.
Physical exercise increases the number of calories that are burned.
Choose an activity plan that is right for you. Consider where it will be done, what equipment is needed, whether it will be done with others, if it can be done in bad weather, what it will cost, and most importantly, whether you will enjoy it. Ease into your exercise program. Start off with activities of low intensity, frequency, and duration. Then build up your pace over the next several weeks.
