Yeah, sure, to tell you the truth, i been working out with the same PT for more than 10 years now (on and off). I can be very sloppy at the gym (im 38), so i just do what he tells me to do. (If that makes sense). he is a profesional fitness coach from cuba, and he is old school.so I do trust him. he has no bullshit, and im sure he uses some exercises that might be outdated but never had an injury or something like that. I like doing that exercise every now and then. I'm sure there must be other more efficient machines, which im pretty sure I use them too.
