I am very excited, yet a little tenative about joining this group. I had a right THR 1/15/2010. The procedure went well & I had an excellent recovery and have been working out since 12 weeks post-surgery. Mostly biking, elliptical & fast walking. I have managed to lose 25 lbs in that time, but really want to lose 20 more. With that in mind I started adding a little bit of running in with my walks. I was told by my doctor to never run. Wanting to not believe him I started googling about running on a THR . Most articles said NO! However one thing I read made me reconsider running as an option. It was about the load on your hips during certain activities- the load with walking 3 mph was 3.75 & running 7 mph was 6. Well I was walking @ 4 & running @ 6- so I didn’t see a significant difference! Still I was afraid. I kept running a little & surfing the net for info. About 4 months ago I googled again and that’s when I found hiprunner.com. I bought the e-book & was convinced it wasn’t as risky as I was lead to believe. So I bought a new pair of running shoes (Nike Pegasus) and started a Couch to 5k program. I ran into a little trouble once I started running- but on the non THR side. I got a bad case of Piriformis Syndrome & was forced to back off. Currently I am doing a run 1 min/ walk 1 min routine for 45 minutes 4-5 times a week. Hoping to do more in the future. Glad to find a group of like-minded & brave (lol) people.
