6 days a week because I absolutely love working out. I didn't at first but i really love it now.
Yea, but you can do too much ya know. The more is not always the better. An important part of training is recovery.
Also, breaking your body up into specific body parts to train each day is a very inefficient way of training. We don't isolate our bodies in the real world. We shouldn't train that way in the gym either. Following your basic body part split takes the functionality out of your training.
Also, tons of volume and worrying about your arms and neck is stupid at this point. You are dieting. That means you're in an energy deficit. Adding any new muscle isn't going to happen, so why focus on such ineffective exercises. Rather, you should be focusing on compound exercises. Something like "the basic lifts" stickie would serve you well.
Specific muscle groups each day so that i can rest some groups for a day or two after i work out with them.
That's the entire premise of full body training. Train 3 days per week to give your muslces a break.
My suggestion to you is to erase all the stuff from your mind and break it down into why you do what you do in the gym.
What is all that volume and blasting each and every body part with isolation movements going to do for you?
That's not what creates muscle growth and/or maintenance.
What does?
Progressive overload of the compound lifts.
That means, get stronger in each of the basic lifts.
Most people don't need more than 3 full body sessions with a handful of compounds, low reps, and a focus on adding weight to the bar. This is what generates the majority of your gains until you reach a point where that doesn't work. Don't muddy the waters until you have to.
About the legs, my legs are huge (all muscle) and they are not propotionate to my body. I really don't want them any bigger. I guess carying all that weight all those years has really built them up. My calves are the biggest I've seen.
Again, if you are dieting, you aren't going to add any appreciable amounts of muscle.
Your legs are genetically big. That doesn't mean you shouldn't train them. Think of your body as a unit. Leaving out one particular section of the unit leads to inefficiencies across the board.
A couple of compound exercises for a handful of sets isn't going to cause you any hare, each week. You could simply do squats and deads and be done.
