Moving your body everyday is very important to your health, especially if you have a desk job. Sitting at a desk has a detrimental effect on your posture and health. Even if you work-out 30 - 60 minutes a day, that work out is basically voided if you sit at a desk all day. Consider taking up jump roping. It is portable and you can do it anywhere, even at your desk job. Just close the door! Check out these instructional videos. It is simple and you will improve quickly. You will also carve your arms and back, what a bonus!
