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?
Mike would need to do activities that improve his cardiovascular system (i.e your heart.) He needs to do activities such as running, jogging, bike riding, etc.
