MMM, this describes me to a T, I run around 40-45 minutes, I must be a relic of the past, old school ie. run until you vomit, I usually have to sit under a cool shower for a few minutes to recover. Should I run within myself for better results?aerobic work is interesting too. if you ask someone to run 20mins (as an example), they'll run that 20 as fast they can so they're practically rooted at the end. the belief that each and every workout needs to leave you in a sweaty mess is rife, and it's why so many folks don't improve or burnout.
