Stop doing cardio and you will never lose your gains—this answer seems like the obvious one, right? It’s commonly thought that in concurrent training—the combined training of aerobic and resistance training—endurance training creates some interference that can limit hypertrophy signaling. As a result, bodybuilders all around have been trying to limit cardio to prevent muscle gains from slipping away, but if implemented correctly, cardio won't steal your gains. From a bodybuilding standpoint, cardio must happen sometimes to create the energy deficit possible to get stage lean. From an off-season perspective, there is some merit to continuing cardio for general health reasons, such as aiding sleep and stress management, and allowing those squats to wear out your quads before wearing out your lungs. I am going to cover how to implement cardio with the least impact to strength and hypertrophy gains.
