Hey all. When I first joined (about 3 years ago) there were lots of posts about cycling but not so many nowadays. I went bonkers with it and cycled a lot (stationery). My machine at home struggled to get to 80rpm but I thought that as long as I went 70/75 I'd be ok. I did worsen. Not a lot but definitely did. Then I realised that the commercial bikes at the gym did the job much better and managed to get over 80. But I noticed that I tended to hover at the 80/82 rpm range and I was pushing hard. I didn't think anything of it. I was over 80 after all but again I noticed a slight increase in symptoms despite pedalling like a madman. I also developed a really odd symptom whereby my right knee (affected side), started to stick outwards after as little as 15 minutes. Some said 'push through it' but I couldn't. It was so ridiculous cycling with a knee about 2 feet away from the bike. I was very disappointed as I thought that cycling would really help, but sadly it didn't (although who knows how badly I might have been without it to be fair).
Then somebody on the HU site commented on how much easier and quicker all this was on a spinning bike. I thank that guy whoever he was! I went back to the gym and went into the empty spin room. I managed 15 minutes before wonky leg stopped me but got to 85/90 with ease. The next time I tried I managed 18 minutes and so on until today I reached 40 minutes which is where I used to be when I started with this shitty disease. It's definitely doing something so I thought I'd write a post on this. The key is a spinning bike and one MUST reach a very high rpm (85 even up to 95). Good luck all. BTW: if I stop with this high rpm, within a week or so my knee starts jutting out again. I'd better not stop then!
