Re: What's a good max box jump?

how about 66" (not on box, over bar).

In college, I worked for the NC State football team and he was a beast then. I have not seen him close up since he graduated, but I can only imagine by the video. 3rd year Arizona Cardinals now.

Re: What's a good max box jump?

So after my C&J lifts today, I decided to try out some box jumps on the biggest box I could find. I managed to hit a box that was about 41"-42" high today (it came up to the bottom of my bicep). I got in 2 good jumps and then I went for the 3rd one without enough recovery and I whacked both of my kneecaps with some really deep cuts. I decided to call it quits after that. Just a word of warning to jump onto something soft and not a hard wooden box.

Re: What's a good max box jump?

Thanks for the anecdote Shane, sorry to hear you hurt yourself. I have definitely said that the "injury to usefullness" ratio of max-height box jumps seems pretty high, but I'm still glad I tried it. It gave me mental confidence and made me realize I could nail way more height that I thought. Because of that I was able to show up my non-crossfitter racketball partner today.

We were warming up (I was doing overhead squats and hang snatches with a 45lb bar, I think he was standing around?) and he saw a 36" box and goes, "man, I don't think I could jump onto that!" and my reply is something like "I guarantee you can jump on that."

Long story short, we found more boxes to stack on the first box and I easily nailed a ~48" jump ("dude, I don't know if you can make that, that's like four feet!") while he (at about 3 or 4 inches taller than me) was freaking out trying to get about 44". Muahaha. Box jumps, and crossfit, for the win!

Re: What's a good max box jump?

How do you think one-legged box jump height would correlate to regular box jump height?

Only one way to find out, right? My gut says the 1 legged box jump would be limited mainly by leg extension strength, and not as much by flexibility and post jump leg speed like a standard box jump, but I could be wrong. A trainer at the box was talking about messing around with these but I'll probably pass as pistols (at least the way I've been able to do then thus far) disagree with my knees.
