Today at the gym I saw a guy doing box jumps with a barbell on his back. Instead of a plyo box (we have two) he was using a bench. He lifted the bar off a rack facing outwards, took a wide stance, did a quarter squat with his knees caving inwards, and jumped, landing on the bench in front of him with a wide stance. At the end of his set he backed into the rack. Then, as if that wasn't dangerous enough, he placed a plastic cardio step (the kind people use for step aerobics) under each end of the bench to raise it 3-4 inches. Needless to say, these steps aren't made for that, and I was half expecting one or both to crush under the strain (he went up to 155 lbs). The worst part however, is that he's one of the trainers.
There was a gentleman doing barbell jump squats onto adjustable aerobic steps inside a squat rack at one of our locations about 6 years ago. Clipped the step, shattered his humerus against the safety bars, extremely messy compound fracture and it looked like he nearly bled out. Probably never regained full use of that arm. I heard — and this may be hyperbole — that he was in med school too. Dumbest thing is, this was a trainer recommended program.
Last year an older lady was doing dumbbell jump squats onto a bosu ball. She said she was trying to improve her "stability." Broke her fibula.
Saw a young girl trying the same move six months later, made sure to stop her.
Last week saw a 60+ year old guy doing wobble board partial squats in the squat rack with his arms so wide he was touching the sleeves. We just got acquired in a merger so I opted not to yell at him, but I did seek the advise of the regional and got the go ahead to stop him if I see it again.
The fact that you saw a trainer doing it is a touchy subject. If he ever has a client do something so stupid, you really ought to put a word in the ear of his manager. If he's just doing that with himself, he ought to be smart enough to assume the risks.
