I want to clarify about the legs press as I think it's a bit confusing.
My gym of 15 years was a somewhat specialized gym in Japan. The owner (Japanese) spent several years in the US in the 80-90s bodybuilding scene and worked as a math teacher (!).
He set up the first personal training gym chain in Japan, and caters to executives, athletes, and entertainers.
I like him, he's a good guy, but we don't see much of him these days as he's getting along in years. We used to chat a lot when stopped by the gym. He put me in the same group as his famous people and enjoyed telling his curious and stunned clients that I'm just a regular "salary man".
Much, if not most of the gym equipment he has was custom-made. The benches, cables machines, power racks, smiths, and yes leg press machines were all made to order. They were clearly not blueprinted and one machine varied or so slightly from the next. There is also hammer and cybex equipment, but it all pretty old. The gym is spotless though.
Regarding the leg press (4 in that gym)...it has several design flaws.
No real safety at the bottom, just a bumper donut at the very bottom. Way low. The safety release handles default to off, rather than on, so easy to miss. I knew all this and used those machines for 15 years (Sunday is my 15 years in Tokyo).
As I knew the machines were sub-par, but had little choice of gyms I accepted what I felt was little risk. Though this accident may have never happened on a proper leg press I don't hold the gym responsible.
I know many might find my view overly generous, but that's me.
Since that day however I have not gone back and we cancelled our memberships. I relocated to a relatively new anytime fitness that's a ten minute walk from my house. It has all the usual AF equipment. I just didn't feel like going back.
I'm now using the anytime fitness Precor leg press machine and progressing my weights and deepening the angle week by week. Started at 60lbs, today was 180.
I'll eventually graduate to the Hammer legs press which my wife prefers. My wife also destroys me on the leg extensions, 120 lbs to my 50. Only way to go is up!
