The Never-Ending Belt March

Trail Log · Movement Breakdown

The treadmill — humanity's ingenious solution to the problem of wanting to run without actually going anywhere. It's the exercise equivalent of a hamster wheel, except the hamster is you and the wheel has a digital display that tells you exactly how far you haven't traveled.

You step onto the treadmill, select your desired program from the console, and start moving. Most machines offer manual settings where you control the speed and incline, or pre-programmed workouts that simulate hills, intervals, or steady-state runs. You can enter your age and weight for calorie estimates, adjust the elevation to make things harder without going faster, and monitor your heart rate through the handles.

Treadmills offer the cardiovascular benefits of outdoor running with less impact on your joints — the belt's slight give absorbs some shock that pavement would not. A 150-pound person burns over 450 calories running at eight miles per hour for thirty minutes, which is an impressive return on investment for an activity that requires no coordination, no skill, and no particular talent beyond the willingness to keep putting one foot in front of the other. Maintain proper posture while running — upright torso, relaxed shoulders, natural arm swing — and only hold the handrails when checking your heart rate or dismounting. The treadmill is the reliable workhorse of cardio: always available, adjustable to any fitness level, and completely indifferent to the weather outside.
