I'm going to include a picture because this could mean a lot of things.
First off, if you are in a fully-equipped gym surrounded by equipment and weights of all sorts and sizes yet you choose to do calisthenics that could be done anywhere you are a bell-end to begin with. If you are in a busy gym you are also an asshole because you are taking up about 3 times as much space as you should be and also occupying a bench, which is one of the main things that people in the gym use.
That's 2 reasons to stop doing this exercise but there is also a physiological reason why you should stop doing this as well.
You are causing undue stress on your shoulders in a very unnatural position
Think about it for a second: Is there any real life situation where this motion would be used in lieu of some other, more efficient method of getting up? I can't think of one. If you were getting up from a sitting or even lying down position there are a myriad of ways in which a person could get to standing without using this motion. Therefore, our bodies through the wonders of evolution never really developed a reason to be in this awkward position.
In extreme situations with bodybuilders who really need to do a little more research and will almost certainly have pain issues later in life you will see someone using 2 benches for these and place a weight or even a stack of weights on their legs in order to make the movement even more difficult.
Now I"m not trying to say that guy isn't in good shape, although he should probably do a few leg days here and there judging by his arm to thigh ratio, but even though he doesn't know it now, he is creating shoulder problems for himself in the future.
The the bottom part of this motion you create a huge amount of stress and strain on the front of your shoulders. The silly part about this is that the entire purpose of this exercise is to work out your triceps and I don't know how much time you spend in a gym, but there are usually a TON of different machines and exercises that a person can do to work out their tri's.
Instead of being a fool and causing damage to yourself, try these exercises instead
- cable pulldown (using a bar or the rope)
- face-smashers (lying down and lowering a bar or weights towards your face)
- close grip bench press
I'm not trying to tell you what to do and since I am a normie I am quite certain that there are many people out there that are in far better shape than I am. I lift conservatively and with a purpose and after having done some research because I know some older guys that have chronic problems because access to information of this sort wasn't so easy "back in the day." If you are doing bench dips seriously reconsider because you could be setting yourself up for shoulder pain / injury in the future.
Now get out there and get some work done!
