Love this approach so yeah one tweak that helped my knees was aiming for a quicker shorter stride on the treadmill and adding 2 sets of split squats and calf raises on strength days to shore up the hips and lower legs. I also like a 3-up-1-down rhythm: add 1–2 total jogging minutes for three weeks, then hold or back off in week four so joints catch up. Keeping the easy days truly conversational pace made consistency almost automatic.
I had the same thing on a mid size unit. The coating started to bubble at the rim and then flake and i emailed support with photos and a serial number and they sent a replacement basket with no hassle so it is worth a quick try if you are within a year.
While I waited I cooked everything in an oven safe pan or loaf tin placed in the basket so nothing touched the peeling surface. Works great. Also check how the drawer slides line up. If the basket lip grazes the housing every time you push it in you can sometimes reseat the drawer or slightly nudge the rails so it stops rubbing and that alone slows the damage.
