The Sunny ASUNA 7700 Treadmill from Sunny Health & Fitness is the best manual treadmill for running and more intense workouts. HIIT and Tabata enthusiasts love it. At 167 lbs., with transport wheels and a soft-drop system, this unit is portable and compact—with a fold-up length of 27.5 inches. Surprisingly, it has a very high user weight capacity of 440 lbs.
The ASUNA 7700 has two heavy-duty magnetic flywheels at the front that give a smooth ride with eight different resistance levels—you can control the resistance by a gear shift that is easy to reach the user’s right side. Also, the incline is adjustable in 1-degree gradients from 10 to 14 degrees.
Even as it has no fitness console, it does have a rubber gripping surface to hold an iPad/tablet—many users might prefer this. Furthermore, the handrails— made of sweat-resistant, grip-able material—are extensive to allow eight different holding positions.
With the ASUNA 7700, you can walk/run forward, backward, and sideways—you can even do a series of squats on it. In addition, you can do sled-push/drive movements. You can also do climbing exercises—with the hands-on floor, pushing with legs, or hands walking on the treadmill, with feet on the floor.
