Stretching both side of the forearms and massaging to top of the forearm helped me heaps. Do it as often as possible through out the day. Also been generallty fit helps too.
Breathing was big thing I learnt a few years back. You tend to hold your breath when the body is stressed (riding shity tracks or lifting heavy things). Next time try to concentrate on breathing deep and conrolled when riding the nasty stuff. Also loosen your grip on the bike at every opportunity, down hills grip the bike with your knees (thanks Crash) and relax your upper body. Makes a big difference to getting through the day.
Bike set up is important too Eags, as Gav said costs you nothing to move bars around. Pick a section of track you don’t like much and do a few times with different bar setups.
The Dynaflex is a cool thing. I had a go of one at Suttos once. Really works the arms but big muscles only let you lift heavier things not have the endurance to ride all day.
Oh yeah and RIDE MORE!!!! :laugh: :laugh:
