Find the first moving component
Walk at the normal pace while another person observes the treadmill, floor, desk feet, lifting columns, desktop, clamp, arm joints, and screen. Tightening the arm will not fix movement that begins in the floor or desk frame.
Level and tighten the desk first
Confirm that every foot contacts the floor, leveling pads are adjusted, frame fasteners are torqued according to the desk manual, and the desktop is secured. Test at seated and standing heights because column extension can change stability.
Shorten the arm's lever
Move the arm post closer to the monitor, reduce forward extension, and center the display over a stronger section of the desktop. A screen held far forward amplifies small movement at the clamp.
Tune tension without overtightening
Adjust lift and tilt tension using the arm instructions so the monitor holds position through its supported range. Do not force adjustment screws beyond their limits or treat extra tension as a substitute for correct monitor weight.
Reduce walking speed before changing hardware
A slower pace and shorter stride often reduce transmitted motion. If the screen is readable at a practical pace, replacing the desk or arm may offer little benefit.
Separate walking tasks from precision tasks
Use walking sessions for calls, reading, or light work and pause for detailed design, spreadsheet, or cursor-intensive tasks when movement affects vision or accuracy. An adjustable workstation should support changing posture, not require continuous walking.
