A friend was describing a movie they saw but didn’t know the name. The only scene description I have is that a guy was trained to jump really high by being put in a well with ankle weights and trying to jump out. Eventually he was allowed to remove the weights and jumped out easily.
Kickboxer by JCVD? I don’t recall a lot of details but he had all kinds of crazy “rocky 3” style training like having coconuts dropped onto his abs while he flexed and stuff.
Yeah I originally thought Kickboxer too, but I don’t remember any jump scene like that and I watched the training section on YouTube and it wasn’t there.
I remember that scene in a movie, but I cannot find it. I know that’s no help to your request, but I thought it would at least let you know you’re not imagining it. My google-fu was weak!
I took the liberty of posting your question elsewhere. Ask your friend if it might be this 1976 movie, which was released under the titles “Shaolin Temple” and “Death Chamber” in the US.
