Weight - A measure of resistance expressed in pounds. Weight is displayed on a per-handle basis.
Reps - A rep is counted when the cable travels forward and back (concentric and eccentric) at least 6 inches. Anything less and it will not count. Therefore, partial reps at the top or bottom of a movement will not be counted.
Energy or Work - The amount of energy needed to move a force a certain distance. The formula is Weight x Distance and is expressed in Joules on the touch screen display. Since “time” is not a factor, the user does not need to move fast to increase Work. Work is only calculated in the positive direction when pulling the handle away from the pulley.
Power - The rate of doing work. The formula is Weight X Speed and is expressed in watts. Power is only calculated in the positive direction when pulling the handle away from the pulley.
Power Use Case: Power is a great metric when explosive moves are being done. Improvements in power are not only great for the athlete but for anyone looking to improve quality of life. One example of measuring power is to ask your client/class to put the hip belt on and attach the right and left carabiner to the loops on their hips. Hold the plus and minus buttons down together to reset watts, reps and joules. Now ask participants to do as many jump squats as they can increasing and decreasing the resistance as needed and asking them to go all out as fast as they can jumping as high as they can. After they complete the set look at the reps completed and the watts created. Let them take a break and when they are ready, ask them to do the same number of reps and attempt to increase the watts. Track the best score and see if they can beat it next time they attempt the exercise.
