One of the most popular use cases for the f1 is indoor walking — on treadmills and walking pads. On a treadmill, start at a slow speed (2-3 km/h) to get comfortable with the four-point rhythm. Place the stick tips on the belt, not on the side rails. For walking pads, the compact f1 (starting at 62cm when collapsed) is perfectly sized for home and office setups. Many users combine walking pad sessions with standing desk work. The upper body engagement transforms a passive walking session into an active full-body workout. Pro tip: Start with 10-minute sessions and work up to 30 minutes.
