I started running around 3 weeks ago and today I finally hit one of my goals: running 10 km without stopping.

I ended up doing 10.1 km with an average pace of 6:29/km.

I’m 15 and mainly do strength training, so I’m still pretty new to running. At the beginning even a few kilometers felt hard, so I’m honestly surprised I managed 10 km already.

Does this sound like good progress for a beginner? And should I keep focusing on slower Zone 2 runs for now or start adding faster runs too?

Hey, I’m 15 years old, 190cm tall and currently around 76kg.

I train at home 4x a week with adjustable dumbbells + a bench and also jog 2x a week. I’ve been cutting for a while and lost a decent amount of weight already, so now I’m relatively lean but still have a bit of a skinny-fat look around the lower belly.

I’m planning to start a lean bulk/recomp at around 3000 calories with ~150g protein daily. My goal is to build muscle while keeping fat gain as low as possible.

My question is:

How bad is it really if a decent part of your diet is “junk food” (for example eating a frozen pizza almost every day), as long as:

- calories are controlled

- protein is high enough

- you still get fruits/vegetables and enough nutrients overall

I don’t only eat junk food, but I do eat a pizza pretty often because it’s easy and fits my calories/protein. The rest of my diet is usually pretty protein-focused.

Have any of you still built good muscle and stayed relatively lean eating like this, or does it noticeably hurt progress/body composition long term?
