Start jogging to increase your stamina and energy. In the beginning, it is best to start slowly. This will allow you to prepare yourself both mentally and physically to go the distance. By taking the time to really learn proper jogging strategies and techniques, you will reduce your chances of straining muscles.
Gradually shift from walking to jogging. Do this by alternating between jogging and brisk walking. Continue alternating between the two for 20 minutes. Remember to walk immediately after you finish jogging. This will keep the muscles you used during the jog from feeling worn down and it will improve your endurance, allowing you to jog further. Over time, you can gradually increase your running time and decrease your walking.
Give yourself a cooling off period. Get into the habit of doing a cool down routine at the end of each jogging session to help your body gradually slow down from your jog. Start with a brisk pace and then walk slowly for about five minutes, followed by five minutes of stretches.
