This program provides the ultimate fat burning workout.HR Hill (65-75-85%)HR Hill simulates hill training by changing the Target Heart Rate thru 3 different percentages. The changes will occur as follows: 65% - 75% - 85% - 75% - 65% -75% - 85% etc. Each percentage will be held for 3 minutes before changing to the next percentage.HR INT (Hill Interval)The HR INTERVAL program alternates between 65% and 85% of your Max HR.
