If anyone could advise me on the following I’d be very grateful. I am significantly overweight (17 stone) and recently bought a running machine to help shift the flab. I started out doing fast walking - 4 miles per hour - but I’ve recently started to crank it up to 5 mph and higher which means I’m running properly. That’s great but I suddenly recalled people saying that running when overweight can damage your knees very badly, sometimes even to the point where an operation is required. So it would good to know if anyone thinks my knees might be an issue given my weight - ie should I stick to fast walking until I’m down to, say, 15 stone? And, because they’re ‘sprung’, are your average running machines better for your knees than running on the street etc?
Sorry for all the questions and thank you!! Ed
