@kalanouc , we’re gonna need some context.
Height, weight, training/nutrition plan, why you’re actually posting a pic when you haven’t even gotten through 20 good workouts, etc.
Based on that pic alone, you’re skinny and naturally lean. That’s about all the feedback you’re due so far. More info can yield more input.
A physique evaluation after 3 weeks of training is like taking a language proficiency exam after 3 weeks of spanish classes.
You need more. More muscle, more time, and more patience. You’ll get there.
Height: 6 feet
Weight: 146 pounds
No nutrition plan
Fix this, immediately.
What have your three weeks of training looked like?
What’s your goal?
