Work is force multiplied by displacement. It's the distance you have lifted a load multiplied by the force required by your muscles to do so.
Power is work divided by time. This can be understood 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.
A ratio comparing the amount of time spent completing work with the amount of time spent resting or transitioning between movements.
The average number of repetitions completed over one minute of time. This is displayed individually for each exercise in a workout.
