Just like our gym, I really can't compliment those fitness instructors. Either bring a beer belly to tell you how to lose fat and gain muscle, or bring a thin monkey to talk to you about how to make yourself stronger.
Please, can you at least make your figure look more symmetrical, and then come and sell me your fitness classes? Your theory is more than practice, isn't it? Strong mouth is king?
Anyway, when I went to our gym, these fitness instructors stood together in groups of three or five, with their hands on their chests bragging to each other.
Then I laughed and felt like two idiots. If you have time to practice your strength, maybe someone will take the initiative to ask you to be a tutor.
