Cadence is your pacing. NEXUS provides this data for each exercise independently as you cannot complete heavy Barbell Cleans at the same Cadence as you can doing Double Unders. Depending on the exercise or workout, you may choose to increase or decrease the amount of repetitions you complete per minute. A higher cadence will give you higher power output, but will also fatigue you quicker. Find your optimal cadence to minimize the rest required to complete the exercise or workout in the shortest time possible.
