We’re all busy these days and it can be hard to find the time to fit in a workout. For some, an occasional jog or bike ride is enough. But for most of us, we need a personalized schedule that gives us time for exercise. Working out can start at your desk with an office-based exercise program like The 30-Day Workout Challenge or at home with a workout DVD like Jillian Michaels’ Inner Strength Workout. But there are also many apps and websites out there that offer advice on exercising around your lifestyle and different fitness plans, depending on what’s important to you.
