… workout programs

The equipment gives you seven workout programs to choose from.

Program One – Manual – Just press start and begin your workout.

Program Two – Target Distance – This program gives you the flexibility to select your distance in either miles or kilometers. The machine will count down while you adjust your speed and incline manually.

Program Three – Target Time – Users can set time to count up or count down from a pre-specified, manually adjustable program.

Program Four – Target Calories – Simply enter the number of calories you want to burn and begin. Adjust the speed and incline level at any time to meet your needs.

Program Five – 15 Minute Pike’s Peak – After a short warm-up, the 4.25 will progressively increase the speed to a peak speed in the middle of the program and begin to taper down to a one-minute cool down at the end. There are five levels of intensity to choose from.

Program Six – 30 Minute Diamond Head – After a short warm-up, the 4.25 will progressively increase the speed to a peak speed and hold that speed based on the level (1-5) you have selected. The program will very slowly lower the speed until it reaches the two-minute cool down.

Program Seven – 45 Minute speed intervals – This is the perfect cardiovascular training program for athletes, fitness enthusiasts or those looking to lose weight. Select your level (1-5) and the 4.25 will alternately increase and decrease the speed.
