I had a thoracotomy in 2008, and my chest muscles were cut horizontally. Now I want to continue to keep fit and exercise my muscles. What should I pay attention to when practicing chest muscles? How to practice? It is recommended to consult the doctor again and practice under the guidance and advice of the doctor. Fitness is for health. If you hurt your body for fitness, you will put the cart before the horse. I'm sure you don't want to see such a result. You've only had chest surgery, and it doesn't affect the exercise of other parts. You can start from other parts, such as arms, deltoid muscles, biceps brachii, core strength exercises and lower limb exercises. Fitness is a whole systematic project, which requires comprehensive planning. It is easy to grow up after you go up to practice bench press. Then there are the old diet problems and sleep problems. I believe you understand these two points, so I won't go into them one by one. Good luck.
