Ugh, the digital art girls are back with another derivative gimmick...
It's basically just another attempt to cash in on internet culture by slapping some glow sticks and vampire faces onto a tired gym aesthetic. How original. Apparently this is supposed to be 'edgy' but it's the same boring schtick rebranded as 'Spite Transylvania'. Groundbreaking. I've seen this exact thing done a thousand times before on DeviantArt.
