The formula for calculating training volume during a workout is expressed as repetitions multiplied by weight. This is because training volume considers the total amount of work performed in a workout session, which is influenced by both the number of repetitions completed and the amount of weight lifted.

When you multiply the number of repetitions by the weight used, you arrive at a total volume that gives you insight into the intensity and workload of the exercise. For instance, if an individual performs 10 repetitions of an exercise with a weight of 50 pounds, the training volume would be 500 pounds (10 reps x 50 lbs = 500 lbs). This total volume helps in assessing the effectiveness of a training program and can be useful for tracking progress over time.

The other options do not accurately represent how training volume is defined within the context of strength training and fitness assessments. Adding, dividing, or subtracting repetitions and weight does not yield a measurement that reflects the actual workload performed.
