mike wants to improve his endurance because he wants to try out for the cross country running team in the fall. he works out at the local gym a few days each week and does a variety of activities, but he still feels like his cardiovascular fitness needs improvement. what would be the best thing for mike to do next?
Work up more then a couple times a week every day but not Sunday for al long as you can and if you want to run base all of you extra time on leg work
