I don't ride much other than my commute but try to run 3-4 miles plus 100+ crunches 3-5 times a week [Should be doing push-ups too, but bum shoulder for last couple months says no]. Being in the USAF I pretty much train to stay healthy and specifically toward the Physical Fitness Test (PFT) requirements (30% Body Comp [BMI<25], 10% Push-ups, 10% Crunches, 50% Aerobic [1.5 mile run for time]). Used to really hate running [especially when I lived above 6,000 ft], and while I won't say I like to run, at least I don't hate it now.
