Does cardio REALLY kill gains?

Cardio improves gain by providing more oxygen to muscles and improving recovery time.

Also it strengthens the most important muscle.

It can downregulate shit like mTOR and increase cell apoptosis in muscles. So less muscle growth and more muscle wastage potentially.

Cardio does not kill gains

Cardio also isn't just running

Get off while you can

the dick?

cardio makes gains. it puts blood in the places it needs to be to lift and recover.

the reason why people say cardio kills gains is because you can't recover optimally from both lifting heavy and doing enough cardio to strengthen your heart. conditioning is good because you can do that while lifting heavy, cardio isn't. cardio however is good when lifting moderately because you don't have to worry as much about recovery.

Only if you do intense cardio daily fuck nugget, stop making excuses.

I've never understood the anti-cardio attitude, I always thought that the most impressive people are the ones that can bench more than 1.5x their body weight and still run a 5 minute mile.
