Step 1: Determine you goals. If you want a stronger heart, lungs, or want the pounds to drop, choose something "cardio." (FYI- cardio can be slow and steady or quick and sweaty) If you want to get a little more tone or definition, focus on strengthening exercises.
Step: Find the time. If all you've got is 10 minutes, use it! Do that two or three times a day and mission accomplished. The harder you push yourself, the quicker you can be done and vice versa.
Step 4: Make movement social. Social time does not have to revolve around eating. Take walks with friends and family. Walk around the mall. Play Frisbee or ladder ball at the park. Play a dance game or hide or even tag- you might wonder why you stopped as an adult.
Step 5: Use your body. Weather permitting, you can walk or bike anywhere. Also try milk jugs for dumbbells, resistance bands, or even having a friend push steadily against you for weight resistance.
What other exercise ideas do you have? I would love to share them.
