Your question is difficult to answer. If you are dealing with people who have been in the gym longer than you, then you can't fight any of them. If you are dealing with a man who has been practicing Sanda for half a year, then you can't beat him. If your opponent has been practicing traditional foreign boxing for two or three years, you can't beat it in the gym for many years. If you are dealing with one or two thin thugs, then you can't beat them, because their actual combat experience is much richer than yours. You can probably hit someone who goes to the gym for three days to fish and two days to dry the net. However, if the other side attacks you, you can't win. Ha ha. Strong muscles are not the same as fighting.
