For each case study, you must develop an appropriate exercise prescription.  Use the FITT recommendations from the ACSM guidelines. You will need to calculate a workload for the particular type of mode of cardiovascular exercise you choose utilizing the metabolic equations. Once you pick an appropriate intensity, use the VO2R equation to calculate the oxygen consumption. Then use that to solve for the workload on the treadmill or cycle, whichever you think is best. Don't forget to indicate frequency and duration...
