I don't think it is a good idea to completley remove cardio, it has many benefits.
However you don't need to be knocking your pan in every day to see those benefits. There's no way you should be going for runs or whatever.
Something like going for a brisk walk for 30 minutes, 3 times a week is perfect. This should actually improve recovery and help you gain.
Getting your heart rate in the 130-150 range is the aim. You should be comfortable whilst doing it and feel fine afterwards.
This will not be a problem, as you will be stuffing down even more beef and eggs to compensate.
That's my two cents anyway,
