Yes, you can. World champions are not born world champions, but training day after day. So even if the starting point is low now, you should know that a strong body shape is not born, but needs to be earned every day. You are in poor shape and have no foundation. You won't have no foundation all the time. You can be such a person as long as you are willing to work hard. Your path can't be smooth sailing, and you will lose what you have won so easily. Without the process of hard work, how can there be a good enjoyment? As a fitness instructor, after learning professional knowledge, you will understand how to exercise, how to lose weight and how to gain muscle. Therefore, body shape is not an obstacle to becoming a fitness instructor, and the contribution will be directly proportional to the harvest.
