The summer time is a GREAT time to get your workouts done outside!
For those who do not have a gym membership this is also a great option for you.
Working out in your neighborhood or at your local track give you the chance to do a variety of exercises!
If you can not run jog for 30 seconds and then walk for 45 seconds. You can try sprints, lunges, squats, or do a circuit training workout. You can even run up/down stairs. There are SO many different things that you can do outdoors.
