Diane is one of the classic CrossFit girl workout, also one of the best short time domain ones as well because of how the muscle groups needed for each of the two movements are completely opposite.
This the perfect recipe for jacking up somebody’s heart rate because different parts of the body are being used, especially with relatively low rep schemes. The heart is what is challenged most because it needs to pump blood everywhere.
Over the year I have programmed quite a few different variations of Diane. A few examples is the one above, three others either contained wall balls, t2b, or pull up. All these additions did was change the workout from a cardiac demanding sprint to a more enduring upper or lower body “sprint”. I use that loosely because it is likely that most will not be able to perform the whole workout unbroken with the addition of the other movements.
