Modes of Operation
- Walking Mode (Under Desk): When the handrail is folded down, the treadmill operates in walking mode, with a speed range of 0.5 to 4.0 mph. This mode is ideal for working while walking.
- Running Mode: When the handrail is raised and locked, the treadmill can be used for jogging and running, with a speed range of 4.0 to 7.5 mph. This allows for more intense calorie burning.
