Here is one consideration before I visit Decathlon: a. I have no interest in running up hills or stadium steps as I once did 50-years ago. b. But, I need an inclined walk, every other day, to avoid atrophy, which everyone suffers eventually. c. So, if I never plan to use the treadmill for running or jogging, but exclusively for normal-paced walking, but wishing the same "hill-climbing" benefit, then What is the minimum-capacity treadmill machine that might suffice? The machine must last for 2 years, minimum. Reliability is a must, but any unnecessary addons are not appreciated? Any suggestions you can make, based on your experience evaluating machines, at the time you made your purchas?
