Interval – the Interval program changes "Speed" to raise your heart rate for a short period and then reduces the speed to bring your heart rate back down again. The starting and maximum speeds vary depending on the level that you chose but range from a starting speed of 1 MPH in Level 1 to 4 MPH in Level 5. At each level, the speed will increase by 3 MPH during the sprint portion of the interval. The length of the sprint period will depend on the length of the workout that you choose.
Hill Climb – the Hill Climb program lets you set the Speed that you want to walk or run and adjusts the Incline to increase and decrease the intensity of the workout. At Level 1 the incline ranges from 1 to 6 degrees and at Level 5 it varies from 5 to 10 degrees. This program tends to keep the level of Incline higher than the "Weight Loss" program and is an effective program to improve strength.
Weight Loss – the Weight Loss program is similar to the Hill Climb program in that they both vary the incline and keep the speed constant. The difference in this program is that rather than being set for a specific time period, the workout is based on distance. During
