RVDWResearch comparing resistance training alone with resistance training + cardio generally finds no meaningful difference in whole-muscle growth. So yes: you can run, cycle or do other forms of cardio while building or maintaining — muscle. But there’s an important nuance. This is where the so-called “interference effect” comes in. When endurance training creates a lot of additional fatigue especially in the same muscles you’re trying to grow it can interfere with your ability to perform and recover from your resistance training. Running may cause slightly more interference than cycling, but the overall effect on muscle growth appears to be small. So if maximizing muscle mass is your main goal: • Keep resistance training the priority • Avoid turning every cardio session into a hard endurance workout • Manage your total training volume and recovery • If possible, separate demanding cardio and leg training • If you have to do both in the same session, lift first when muscle and strength are the priority • Eat enough calories and protein to support your training #hybrid #fitness #running #weightlifting
