2. Don’t jump right in
If you haven’t exercised after your college or have never ever really exercised in your life then you need to realize that you might face stern difficulties in the beginning, as the body needs time to get accustomed to new routines, especially after forty when any change is not easy. Changing lifestyles require greater effort but don’t be disheartened by this fact as nobody is a born runner and everyone experiences the awakening at different stages in their life. So what you can really do is, start your running regime with brisk walking, devote few days of beginning to walking and warm up exercise, slowly pace up towards running by increasing your stride rate. Do not try to be a hard runner, in the beginning, it will only take your muscle pain to a level that will require you to take a long rest to be back to running. The key, in the beginning, is to start running slow, let your body adapt, develop stamina in slow-paced running first and after a while when you feel that you have reached a certain level, then aim for a higher level. This will not only keep you consistent but will also increase stamina for future runs.
