God that guy sounds awful.
Often men are conditioned with a “work through the pain” attitude and raised with a lack of emotional IQ. They’re taught to push themselves at all costs. All they know how to do is push push push, to the point of getting injured.
That workout sounds brutal.
What gets me the most about it, is the speed, with the weights combined!
I’m no fitness expert, but what I’ve found personally is that when it comes to strength training I get more results going slow. Lifting a weight slowly and feeling the resistance usually gives me a way better workout rushing through a set as fast as possible. Plus then I have enough time to actually feel my body and become aware of what part of the exercise is the hardest and know my weakness to better work on them!

If you’re going as fast as possible, that sounds more like cardio, but with the number of weights you had, how is that cardio? Also for me, going that fast can lessen the quality of form if you’re doing cardio. I love cardio, but not at the expense of harming my body with poor form or too much weight.
