I'm 38 years old and started strength training from 20 14. Because of the eagerness for success, excessive compression caused lumbar disc herniation, which has now recovered to 60%. But in order to make myself stronger, I have to be self-reliant in this insecure country, because I have neither a backer nor a golden mountain. No matter how strong I am, I can seek self-protection and protect my family in some dangerous and sinister situations. Now the recovery training is under way, and the strength is steadily improving. I believe I can exert my extraordinary strength. Remember not to overdo it when you start training. Keep it a little bit to ensure that the strength and pressure are within the range that musculoskeletal tendons can bear. Step by step, let it gradually adapt and then add weight. The best interval training is to practice three times a week, one day at a time, and then another day, so that all tissues of the body can be buffered and recovered without being particularly tired. Finally, I wish you success! I also hope we can communicate with each other in the future!
