1.5 years in the gym, currently 19 years old! Can you tell me my current percentage of fat and tips with the best exercises for abs?

1.5 years in the gym, currently 19 years old! Can you tell me my current percentage of fat and tips with the best exercises for abs? I am currently in a lean bulk with a certified trainer and the truth is that everything has gone well with the reverse diet (before I was overweight 30 kilos above my height but from pure fat I was sedentary but now I usually study how I train and sleep I have almost forgotten I love Gregg Doucettw videos 😎)
