Mountain Dog Arm Training

How many times per would should I follow this Arm Training routine? Should I just add it in once per week and make it my only direct Arm Training? My goal is to add muscle mass in overall but want to increase my arm size right now. Are there any other hypertrophy programs you can recommend while following this arm training? Thanks

What’s your current program?

Just finished a Strength hypertrophy cycle using 4 to 6 rep range for all lifts 4 days per week.
