Sorry I didn ' t mean that to be insulting , I meant it like , I think it ' s too simple of a task to really benefit from it . But of course anything is possible . I don ' t think anything exists but I should think the Arduino can do something like that . <| sep |> Smart enough to know when I don ' t know something . You ' ve never heard Smart people question everything , idiots are always certain ? I think it ' s hilarious the only place anyone ever dares to insinuate I ' m stupid is on the internet . <| sep |> One of the reasons people arch is because their shoulders are closed and tight . If you open the shoulders by working on flexibility in that direction , you ' ll be able to hold a straighter line . This will help put your core in a stronger position and the bones will stack a bit better . It ' s also an admirable goal to do HSPU ' s with a straight body hollow body as it ' s very difficult and looks amazing . Also , if you ever want to do any OneArm HSPU progressions , you need to have a straight HS to have success with them .
