Does the site mine at the expense of visitors?

Question

Malware

Hello.
I came across a site that loads the processor by 100%.
The first thought is mining through the browser.
I would be grateful for help in determining if this is really mining and in describing how to determine this script.
Site: fitness-apelsin.ru
Screenshot of CPU loading: https://habrastorage.org/webt/59/d4/c4/59d4c4d5039...
PS AdBlock solves this problem
PPS I already wrote to the VK group about this problem on their website
