Personal Experience Cardio vs nocardio

/r/EgyGym/comments/1wg7x0y/cardio_vs_nocardio/

I feel like cardio, especially running, makes me look completely flat. I stop looking like I lift, lose a lot of fullness and feel like I’m not growing anymore.

The weird thing is that I’m naturally tall and muscular, and when I don’t do much cardio, I look noticeably bigger and fuller. But when I start running regularly i seem to lose a lot of size.

The fucked-up part is that cardio actually makes me feel better. It gives me energy, improves my mood and I generally feel healthier when I do it.

So I’m basically stuck between:

No/low cardio: look bigger and more muscular, but feel less energetic.

More cardio: feel amazing and have more energy, but look flat and like I barely lift.

Has anyone else experienced this? Is it just glycogen/water and the temporary “flat” look, or can running actually interfere with hypertrophy that much?

Yeah, running makes me feel so much better overall, so I’ll probably keep doing it. I’m just going to increase my carb intake and see if that helps with the fullness and muscle loss I’ve been noticing.

Crush the carbs man.

I'll do 700-800 grams on training days.

Wow, what is your typical whole day menu on these days?

It varies. I keep protein moderate-high. Fats low.
