I bought one package of these dice for each of two friends of mine who asked for some advice on workouts. I don't have a package of these so can't describe the quality, but the concept is similar to some dice I do use. Roll one die for the number of reps or minutes and one for the exercise. This gives 18 different exercises that could be done for a total of 54 ways. With the variety here, you could just roll the dice each of the dice and do that set of 3 exercise several times. However, there are some "cooler dice" out there - 12 sided dice - but they are more expensive. Those have the number of reps/minutes on die face and a picture and a name of the exercise.
