In reply to jackda21:
Yoga would be great for improving flexibility to help you climb better. About 20 years ago I did yoga for 5 years and thoroughly enjoyed it. But I stopped doing it and lost my flexability.
At the moment I am on sick leave and three months ago I started doing palates, 5 days a week, at my local Sport Centre. I was not too sure what it was at first, and thought that it would be a poor imitation of Yoga. I was wrong and found it more beneficial to me than yoga.
When I started 3 months ago I had very poor upper body strength, which was why I was off sick. I discovered that Palates is quite a recent activity which I think started in the 80's. This means that a more scientific approach has been put into the exercises to isolate specific muscle groups to work on at a time. Palates mostly works on your core body strength which is an excellent foundation to improve your upper body muscles.
During my stint at Piletes one of the teachers went on holiday and we were given a Yoga teacher for the session, which I was looking forward to as I enjoyed yoga many years ago.
The whole event left a bitter pill in my mouth and I doubt I will ever do yoga again. Normally the Pilates would come around the class and correct your body posture to ensure that you were doing the exercises correct and not injuring yourself. The Yoga teacher just sat at the front of the group and directed. She had no desire to correct our body postures or explain what it was that we were to achieve. As a result I left that class with a sore back where I had to stop exercising for a week.
Looking back on my Yoga days, no instructor ever came over to correct people's body postures. It was assumed that if you wanted to progress then you would research the subject yourself on the correct form.
Yoga is a very noble form of exercise with thousands of years under its belt and you will indeed become more flexible which will aid your climbing.
From my own personal experience, I much prefer Pilates as it does the same thing but works more on your core abs and back muscles than yoga does. The tutors correct your posture and more importantly the class is not always full of retired women. Sometimes I get to exercise in the company of some hotties. They may not think the same about me, but it does make the pain of stretching my muscles all the more worthwile.
