Box jumps are used for explosive training, with a reported best height of 50 inches.

“I got my boom box here and because I'm sort of on this quest to get rid of EMFs in my house and home environment. You guys will laugh at this. I actually hardwire the boom box into my phone so that it's even bluetooth thing but that's because I'm crazy. I don't know. I listen to all kinds of stuff when I'm working out. Sometimes rap, sometimes hip-hop, sometimes electronic music but that thing cranks man. I've got my boxes for box jumps. My best height I think is 50 inches 5-0.”
