Thanks Scott for the answers. First I'd like to mention that video you just posted I think is the, or one of the best and most important videos you've made, I made every single mistake that is mentioned there and that's why I only got stronger but pratically gained almost no muscle first couple months! So hopefully that will help other guys too since that advice is literally what has helped me start gaining weight finally.
Anyway, of course I have a few new questions I've come across :)
1. Do I need to do cardio? I ask because I have never considered it as a good idea since my goal is too put on as much muscle as possible atm, so cardio seems to be completely irrelavent and even counter productive since that will burn more calories. However I recently saw a video by someone who so far has given pretty good videos but this is something I'm not sure about: He said that even if you're someone in my situation you still should do a bit of cardio (like HIIT) for cardiovascular health. I thought any exercise lifting, running, swimming counts as being good for keeping the heart healthy, which is why this was surprising. So do you think doing cardio is necassary for me as I do want to have good heart health? I honestly don't like cardio much and highly prefer lifting almost everyday, and either taking one day off after PLP or doing a ab workout (Does this count as cardio?).
2. What is the main difference (in terms of building muscle), when using an ez-bar vs straight bar, I see Steve Cook especially in some videos he uses Ez-bar for heavy bicep curls and for skull crushers etc... so what is your opionon on straight-bar vs ez bar for building muscle, or do just suggest to alternate between those sometimes?
3. For dumbbell chest press regardless of incline/flat whatever, do you like to turn the dumbbells as you go up to the top position, or just press directly up? Seems to be a lot better activation in the chest when you turn them as you go up? Yet I see almost no one suggesting this and I don't ever see you doing it in any video with a dumbbell bench press.
4. And lastly another thing is, what is the difference between a dumbbell (or barbell) bicep curl vs doing the same thing except starting in a neutral position and supinating the hand as you're going up? I see many people doing this and I don't understand which one is more effective? Or is it one of those things you alternate? I always thought that barbell or dumbbell you should start in the supinated position...
Anyway, thanks again for all the help and more good questions coming soon :D
