The person, probably female, is doing a behind-the-neck lat pull-down, strengthening the trapezius and upper lats. She is grabbing the bar with an overhand grip extending toward the bar. If she is still doing this, don't you think her shoulders go up slightly? That is bad for the shoulders. Anyway, your shoulders are at risk whenever you can't see your hands.

I have been working out for nine years but am still an intermediate. Keeping a good form is all. Squeezing your shoulder blades together and not going up your shoulders are essential in most workouts for our safety. Also, when carrying equipment like dumbells, we should be careful of doing it not to drop or fall. Suppose you aim to work out effectively; you need to lift heavier weights little by little or perform more repetitions. It would help if you regularly considered whether you have plateaued or can lift more. That's exactly about me. I've been on a plateau.

I realized my plateau this morning. I used to feel sleepy after workouts, but now I hardly do. Changing some exercises about the chest is necessary. For my reasons, benchpresses should be changed into another safety exercise that doesn't have the risk of dropping onto the body. Heavier weights are required to break my plateau.
