Totally agree with you, what bothers me the most as someone who is regular at the gym is seeing people working out in a completely wrong way! You see that they are trying really hard, but most of them are not performing the correct movement required to activate the right muscle group. And when they don't see any results (of course) they give up, thinking 'it's not possible, I cannot do it'. Like for everything else in life, you need to do your homework before starting, you need to learn how to perform each exercise correctly, and then keep trying to do it until you succeed. People expect to see amazing results in 3 months, but in reality, you need 3 months of regular and correct exercising only to learn how to exercise properly, then you can start thinking about increasing your weights and potential progress and results.
