You can find a boy with abdominal muscles in the gym, but his chances of becoming your boyfriend are very low. Because people in the gym actually practice by themselves, if you look at people too much, you may think that your motives are impure. Generally, gyms are not easy to get caught. Recommend a new gym, HITIE, which has a selfie area, a restaurant and a party. Good-looking, you don't have to be teased for minutes.
