Might be other threads arounf but couldn't find it. Always struggled with arm pump and after got into dirt riding it's worse to the point might have to give it up. So intersted in any tip that could help me redice the problem. What I do today: Do streching several times a day also during breaks during riding Do exercises (mostly hand grips) Try to use legs and be in balance to not strain arms...but not easy for a beginner Try focusing on relaxing grip while riding...but again not easy when bumpy and loose Taking breaks (even short ones hep) Tiger balm (actually a stick lasting way longer, really works) Muscle relaxing, anti-inflammatory drugs (normally take before riding) Try not to use PC too much Will reduce weight and get in better shape, less mass to control and easier having correct technique when not tired Get sme more basic technique training, still not that confident riding standing up Quick action throttle, less rotation=less train Just ordered leg pegs leg pegs (www.legpegs.com). Guess with proper teqhnique, balance etc it's not neccessary but having problems during hard acceleration not hanging onto bars. Worth a try.
