If you consider treadmill workouts not quite tough enough, then hop on the BodyEnergy ($3,999). The motor-free, self-propelled treadmill works both your upper and lower halves, integrating elliptical-machine-like resistance arms to enable high-intensity, full-body workouts. Manual treadmills can be tough to control, but BodyEnergy’s addition of an arm-drive system makes it simple to modulate speeds up to 12 m.p.h. And while motorized treadmills may take several seconds to power down, this stops instantly once you stop running, lessening your chance of taking one of the approximately 22,500 treadmill-caused trips to the ER per year. —Jesse Will
