"Tell me that is not genius" suggests to me that they are saying "it is genius" (and you should think so, too!) "make it to" - the end result here is the same. The first is implying that you can travel to the gym. The second is implying that the gym will come to you (not literally; you can have a home gym) "work out" means exercising, specifically with equipment. EG. "Animals do not exercise at the gym" "Bears get jacked" - get jacked is slang for 'get strong' (e.g. with extra muscle). EG. "Can you imagine a bear that has become very strong?" "Over for us" - likely that animals will take over the world / end our lives, as they would become so strong.
