When I first started on SparkPeople, I used walking for my exercise. Walking is a great way to introduce some fitness into your life, when you aren't used to it. It doesn't require a lot of special equipment (although a good pair of shoes doesn't hurt), and can be done any where.
But really, anything that gets your heart rate up and lasts for ten minutes is beneficial. Dance to three songs on the radio, do some lunges while vacuuming, or climb up and down your stairs at home. Once you get the hang of adding more activity into your day, you will find many opportunities waiting for you to "grab" hold and go!
