Work = Force x Displacement. It is the distance you have lifted a load multiplied by the force required by your muscles to do so.
Power = Work / Time. This can be thought of as "how fast" you completed the work endured, or the intensity of a training session.
In a workout with multiple rounds (repetitions of a series of movements), it is the time required to complete each round.
The amount of work completed compared to the amount of rest taken; expressed as a ratio.
The average number of repetitions completed over one minute of time. This is displayed individually for each exercise in a workout.
