I like jumps on to a box. Great exercise for people playing sport but they shouldn't be overdone.
I also think the idea of doing them for conditioning is retarded. They are an explosive movement and should be done with complete rest. To do them for conditioning gives you minimal explosive training benefit, high injury risk and a shitty conditioning exercise.
