I'm in Tulsa and spend most Sundays planted in front of the TV for Rams games, and my back has started complaining about six hours in one chair. I want to keep moving during commercial breaks without leaving the room, so I'm looking at walking pad treadmills, specifically the Redliro JK06F with the long handrail. The long handrail is the draw for me since a bar to grab would make me feel steadier than the tiny ones, but I have questions. How stable does the handrail feel if you lean on it at all? Does the deck stay put on carpet, or does it creep? And is the walking surface big enough for a full stride without feeling cramped? I don't need to run, just walk at a slow pace with a coffee in hand. If anyone here has used a compact walking treadmill at home, what should I look out for before buying? Thanks.
