The number on the cardio machine is almost certainly wrong. Treadmills, ellipticals, and stationary bikes consistently overestimate calorie burn — sometimes by 30 percent or more — because they do not account for your body weight, fitness level, or actual effort. This workout calorie calculator gives you a more accurate estimate.

Starting an exercise habit is hard. Not because the exercises themselves are hard, but because the habit does not exist yet. There is no groove worn into your daily routine, no automatic pull toward movement, no identity of “someone who exercises.” The 30-day starter plan is designed to build that groove, one small step at a time.

Most people plan their workday around tasks and meetings. Movement is an afterthought — something that happens when you remember or when you have time. The desk break planner flips this logic by building movement into your schedule as a non-negotiable, just like any other appointment.
