after a long day of unicycling i try to relax as much as possible but as i do so i have really achey pains in my stomach. this only occurs when i have been doing trials and have been bending forwards to hop around on stuff.
is this just where i have strained a muscle or is there something wrong with me?
my guess is you just have sore abs. this is normal after a big trials session especially if your going bigger than you normaly do. try doing a warm up and warm down, if you allready do, do slower long ones.
