In fact, you can practice mainly in one place, and the effect will be better. If the difference between the left arm and the right arm is obvious, you can exercise the weak arm more through the method of "learning from each other's strengths to make up for each other's shortcomings", and then exercise the weak arm together when the two arms are almost the same size. If your chest muscles or abdominal muscles are asymmetrical, you can use one-handed push-ups like kneeling (aiming at the asymmetry of the chest muscles), and which side of the chest muscles is smaller, use that hand. If it's abdominal muscles, exercise your weak abdominal muscles by rolling your abdomen and lifting your legs unilaterally. If your lower body is asymmetrical, you can do some exercise, such as riding a spinning bike or jogging. What needs to be explained separately is that it is necessary to pay attention to the symmetrical training of the calf, because it is easy to produce muscle legs. You can exercise your weak legs by jumping on one leg (like the strong push of basketball, which can improve your reaction and jumping ability), and then relax your legs by massage after exercise.
Running is the best way for me to keep healthy. Don't pay too much attention to some comments on the Internet that "running will make your legs fat". However, I tell you, through the combination of running and reasonable diet (remember to stretch after running), your legs will definitely not get fat. So don't have any more concerns.
