I have killed quite a few bears with my bow, and know how to bring em in right quick and close! Burn some maple smoked bacon in a frying pan on a coleman stove.
If you want exercise, smear the residual grease all over your clothing and when the bear shows up, taunt the bear. Guaranteed he or she will chase you!
If you don't bring a gun then you
start running, as fast as you can! Now that is an exercise program in bear country! hehe
