It certainly screws my knees up when I run, so I stick with walking 6-10 miles a day at work instead.Its not terrible for your knees urban myth. The body compensates for whatever injury you have and backs and knees take the brunt of that.
What is terrible and bad for you is sitting in your car doing nothing
So you run 4km or so, your legs are burning as are you insides. You stop and spend 5 mins recovering convincing yourself that your now fitter and healthier.
I would pick running most days as it's higher intensity than cycling and you still get to the parks etc.
You're not cycling hard enough then. You can cycle at any intensity you want
I dont run, but thought I would input my experiences here, several years ago I was just over 18st at 5'9". I was driving to work, then sitting at a desk all day and then driving home, so my exercise was basically walking to the toilet or the kitchen or the printer. About 4 years ago I stopped driving to work and started getting the train which forced me to walk to and from the stations which whilst only about2 miles in total started making a difference. I was slowly knocking the weight off and by the time the first lockdown came I was at about 14st. I then spent 3 months in lockdown doing nothing and put on half a stone again. So then I started doing walks at lunch or after work, starting with a couple of miles around my local area. Since then I have increased those walks and now do a minimum of 4-5 miles a day (at lunch or after work) and on weekends I will do a 7-10 mile walk, so am averaging about 50 or so miles a week. I've experimented with adding jogging in but my knees hate it (years of excess weight), so have kept with walking but at about 4/4.5mph to ensure its actually exercise and not just a nice stroll. I am now at 11st13lb and feel much better in myself.
Well done.
I found walking and lost a lot of weight too. When the weight came down I started running and I've been doing it for 5-6 years now. I've done a couple of marathons and countless half marathons. What I will say is get the correct trainers for you. Not the nice looking ones you see but the correct ones for you and your running style. Proper running shops can help you with this.
Hmm I thought that was a generally acknowledged fact. Although my first google hit seems to dispute that https://www.medicalnewstoday.com/articles/biking-vs-running#muscles-used
Still I would say I feel less destroyed after 4 hours cycling than 4 hours running, not that I've run for 4 hours for a long time
Problem with cycling is that you need much more time to do it. I would say for an equivalent 10 mile run you would have to cycle at least 30 miles. I run 10 miles in about 1hr 12 mins so a cycle would take about 2.5 - 3 hours depending on speed. Having that kind of time after work is not really achievable for me. Luckily for me I cycle to and from work anyway so it's a bonus. It's certainly not a problem at the weekends but during the week it takes to long.
Cycling is very good exercise especially if you are unable to run for various reasons. It's far less stress on your joints but it's the time needed that's the problem for me.
