I’m actually curious about your nutrition/diet vs. what you’re lifts/program are.
At your age, almost anything from a weightlifting standpoint should help stimulate muscle growth.
How many calories are you eating each day? Is this something you’re able to track? How about grams of protein per day?
Skinny fat is a tricky place to be because if you cut down a lot of weight, there isn’t much muscle to make it look good/worthwhile.
These guys did that and more! You’ll be fine.
