Yeah what people can do when determined is pretty crazy. I know several years ago I watched a documentary about Super Max prisons and some of the inmates they house. One of they guys they covered was doing life with out possibility of parole and was like in his 40s and had been in prison since he was like 19. He was only moved by a full team of 5 correction officers in a straight jacket and shackles. They showed multiple prison surveillance videos of him injuring corrections officers when he literally tore his way out of a full on straight jacket like he was Hulk Hogan ripping of his T-shirt. The guy was not even that big, He was on the larger side but nothing massive. He was absolutely ripped though. He basically spent every day doing nothing but working out, like seriously not joking he did like 500+ push ups, Situps, Leg Lifts, and chin ups a day, and I mean 500+ of each 7 days a week. The officers said he spent most of his time in solitary because hes generally only out for 2 or 3 days before he gets in a fight and generally seriously injures a couple guys and goes back into solitary. But watching that guy go from being in a straight jacket to punching out a corrections officer in less then 10 seconds was pretty chilling.
