How about prisoner's fitness? Has anyone practiced successfully? I don't like big men, but I like Bruce Lee's figure. My weight 155, and my height is one meter.
Of course, prisoners' fitness is mainly concentrated in places with small space to achieve the purpose of keeping fit. Bruce Lee's figure looks thin, with little fat and strong muscle strength. Your requirements are height 170cm, weight 155 kg, and figure on the side. If you insist on losing weight to130 ~135kg and keep exercising, according to the book, you can reach the same figure as Bruce Lee by strengthening strength training and flexibility training.
