The BF and I started MTB'ing end of March 2010 and have'nt missed a weekend riding since. The best thing ever... however the hilly parts can prove to be a challenge We are definitely somewhat fitter than when we started out. I'm just wondering if any of you have some tips for us. I have started focusing on my breathing, leaning slightly forward and listening to the voices that scream "Gee hom gas girl!" when starting a climb and must say it does help, but does it really at the end of it just come down to fitness and building muscle (stronger legs)?
