Yeah, I'm a little surprised that the box just tumbled from beneath her without much prompting. If you're going to do a jump like this, I'd want it to be on something very heavy/secure that won't tip.
The box is designed to be useable at 3 different heights... The lowest height is a 20 inch jump on the long end where the box is most stable.
There's a 24 inch mid point.
In most CrossFit workouts, men are asked to use the 24inch side and women the 20inch side.
She is using the tallest and most unstable 30inch side, and I have no idea why.
The boxes are heavy and fairly secure for the most part... But she's a heavier girl jumping with poor form onto the most unstable side of the box.
All of that said.. rehabbing an ankle injury is no joke. I rolled mine going down a set of stairs with the dogs and it took me about 9 months before I felt enough stability and strength in it to go running again, it was over a year ago now, and it still hurts if I overstretch it.
Not only is she jumping on the 30 in side but also off of a plate. If you are going to stand on a plate to jump on the highest side just jump on a lower side
Right!? What a weird choice. I've seen some strange exercise choices in open gym before but that seems like an wildly unnecessary risk and has no functional benefit other than increasing general risk of danger lmao
There is a functional benefit. She probably already did the 24 inch jump and wanted to try going a little higher but the 30 inch side is a bit too much. The plate is about 2-3 inches so she gets a more doable height this way
This goes back to CrossFit being an issue. 24 is easy in warmups and doing 4-8 probably isn't a problem by itself, but is after 3 sets of amrap and a lactic buildup for 15 minutes.
A ton of people do stupid stuff in the gym every day, CrossFit is the only place where the stupid stuff is celebrated.
Second that on ankle injuries. I'm 35, when I was like 10 I just twisted my ankle in a hole running through our yard. To this day, I call that one my tricky ankle because it still randomly locks up on me. This video made me recoil and put my phone down to try to get away from it. She is a trooper for sure, but I wouldn't be shocked at all if she will also have a tricky ankle forever.
I've rolled my ankles multiple times, once to the point it touched the inside of my leg, and I have no issues with them. Granted, I constantly flex and rotate them out of habit, so maybe that'll help.
Because of Muay Thai, grappling, and other martial arts and sports, I've dislocated/sprained both ankles, all my fingers, hyperextended elbows and knees, have had partial dislocations in both shoulders, tendonitis in both shoulders, dislocated jaw multiple times, slipped discs, and a dislocated patella in my left knee and none of those have caused any lingering pain because I've been big on stretching over the years.
Stretching is really, really going to pay dividends. Hot yoga as well, but that's not inexpensive. I'd just recommend 30 mins of stretching every day and I promise it'll at least help.
It's her left ankle, the first part of her body that hits the ground is the toes on her left foot, I'd say it's much more likely to be a sprain or a tear than a break.
All it takes is some over extension in the wrong direction.
Her toe tried to take the brunt of it while the rest of her body, and crucially, her left shin, kept falling forward, stretching or tearing the ligaments around the ankle
The bruising on her mid foot looks like she may have injured that as well. Toe first and twist is a really quick way to both midfoot and ankle injuries. I got a Lisfranc fracture from a similar motion.
It most definitely is. Rogue, and others, advertise the three different heights. While it might not be the safest, it is intended to be used like that.
Box jumps are like any other workout. They are safe if you are doing it right. I have seen more serious injuries from deadlifts than box jumps.
Edit: the downvotes need to take two seconds and Google rogues box, the tag in the Google results is literally 3 heights, 1 box.
No, it is not. If it was designed for that usage then it would be designed with a base that is at least as large as it's height.

They may be advertising this usage but it's not an appropriate design. I'm not going to bother checking out the marketing material. If they are advertising them as you are saying then anyone injured should sue them into the ground.

Yes and that means using properly designed equipment.
I was a dumbass kid who did this with stacking chairs. I get the impulse to test yourself with improper equipment. But just because people can do something dumb without getting hurt doesn't make the equipment properly designed for the use.
This is the same versatile 3-in-1 wood plyo box utilized for years in CrossFit Games competition, with built-in height options of 20”, 24”, and 30”.
American-made, battle tested, and backed by a year-long warranty, the 56 LB Games Box is designed for safe, effective plyometric training at any skill level. Add a box to a garage gym for a new workout dynamic or order in bulk to equip or upgrade a large scale strength and conditioning facility.""
I also remember all the taller plyo boxes are taller than they are wide.
Lots of inappropriate equipment doesn't make the equipment suitable for the activity.
It would be better to use vault training equipment that has been properly designed with safety in mind.
Can you show me plyo boxes taller than say 24 inches that are wider than they are tall?
No. I'm not in the market but I guarantee that if I was I'd never buy and use a box that's taller than it's base for this type of activity.
Can you pull up safety standard that agree with you?
Based on my knowledge of CrossFit injury rates their safety standards are meaningless.
If you're interested in seeing how to properly design for a similar activity check out gymnastic equipment. They're designed with either an extra wide footprint or a fixed weight distribution system that ensure that the equipment won't fall when a person jumps off.
You are moving the goalpost. The claim you were disputing was "The box is designed to be useable at 3 different heights...". You said "No, it is not" twice, "If it was designed for that usage then it would be designed with a base that is at least as large as it's height." He provided proof that it was DESIGNED TO BE USEABLE AT 3 DIFFERENT HEIGHTS, now you are just saying it's not safe.
These boxes are advertised this way, used this way, and are perfectly safe if used correctly. This girl is both too short and too heavy to do a jump on the highest side. step ups on the 20" side would destroy her after a few sets of 20 reps.

You don't know how strong her legs are that's a foolish assumption.

They're not. The box setup like that is a big lever with no weight distribution system to prevent them from toppling over when a person lands on the edge. If it was perfectly safe the box wouldn't have moved out from under her.
The box did not fail, her trainer did.
No, both failed. You can see the box fail as it goes off balance when she lands on the edge rather than on the center. But you're right her trainer should have stepped in and stopped her from using that setup.
It actually is. You could build an internal frame that attaches to a foot, build a harness that attaches to the top, or build the boxes to be interlocking where you add more at the base to add height.The box remains a cuboid for aesthetic reasons while the equipment is still safe.
Wasn't trying to blame her weight.. but it certainly didn't help.
She also landed at the edge of the box with most of her body weight in front of her toes, I was more blaming it on trying to do the 30inch jump...
Especially considering that I've now noticed she's doing it from plates.
If she had put the box on its side and did 24inch jumps from the floor, the height differential would have been almost the same and the box would have been harder to flip.
I rolled my ankle badly playing basketball when I was in high school (over 20 years ago now). I was certain I’d broken it, thought I heard a crack, and I’d broken my wrists a few times so I knew what that sounded like. Went to the ER, got X-rays, and it surprisingly wasn’t broken. My orthopedist then explained that I may end up wishing it was broken, because a clean break will 100% heal in 6ish weeks, while a bad sprain could take months or more to heal. Can’t remember how long it took to heal, I was young, it was maybe a few months because I only played basketball in the winter, and was back playing soccer in the spring.
Now, at 40+ years old, I roll my ankle slightly, not even bad enough to stop playing, and it’ll be sore for ages. :(
I rolled mine while sprinting, heard a crack, went to the hospital because it looked like I'd put a baseball under my skin then decided to go home because we'd already waited an hour.
Two days later I was playing basketball on it. I miss being 14.
The whole point of box jumps is landing in the proper way so that the box does not want to tip. You essentially want to ‘float’ onto the box. I 42F have been doing box jumps regularly and safely for 15 years. You have to build to that height and ability.
Without much prompt? She landed on the edge of the box then flicked it by jumping forward. Same thing as putting your finger on the top edge of a dice, pressing down hard, then pulling your finger towards the edge. Sends that shit flying.
