It might not be the most glamorous way to work out, but the elliptical trainer is one of the most reliable, safe, and effective machines. The key advantage of the elliptical machine is the dual-effect of both upper and lower body cardio and strength building, something that can't be said for bikes, treadmills, and climbers.
Ellipticals require you to walk, run or climb with your lower body while "pumping" your arms back and forth with an alternating push and pull motion. The result is a considerable amount of calories burned – between 200 and 400 in just 30 minutes, depending on intensity and settings. Regular workouts will boost endurance, strengthen muscles from top to bottom, and burn stubborn belly fat.
An elliptical is also a great low-impact exercise method, especially compared to running on pavement or even a treadmill. You'll save your joints and tendons strain by opting for an elliptical session over a jog.
Finally, an elliptical is arguably the safest machine for at-home exercise, requiring less intense focus or coordination than a treadmill. You've got a firm grip on the handles, a platform for balance, and total control over speed and intensity.
