So whats the difference in single muscle group lifting vs full body?

I feel like it's too much resting on my other body parts for the week if i target single groups at a time.

Would it be better to do full body conditioning everyday?

Yes, always.

The truth is that you cannot physically target a single muscle when you lift, and when you try you end up using lacklustre isolation exercises that are usually only difficult because of poor leverage rather than actual muscular effort.

Even with a curl, you are utilising the forearms to grip the bar, the bicep as a prime mover, the brachialis as a synergist, the tricep as an antagonist, and the shoulder girdle to stabilize the arm.

Not to mention the core to stabilize the trunk.

Training with large compound movements will elicit a greater hormonal response, and thus larger cause for the body to adapt and grow simple because they utilize large amounts of muscle across multiple joints.

Why accomplish an inferior amount of work with 4 isolation movments, when you can achieve even more with a single compound?

I.e. - Hyperextensions, shrugs, reverse flys, leg curls and calve raises....or deadlifts.

Thats just a real no brainer

"Pencil necks" is what we used to call guys who did a lot of isolation exercises. Their necks (and usually the traps too) were greatly underdeveloped.

Balance should be the key word in your training. You should balance the isolation with the full body work; you should balance all the muscles; you should balance in endurance, strength, stamina and power. How you finally decide to balance it is your decision, but make it a decision and don't just let it happen to you.

It is one thing to have a body that looks good; it is another to have a good looking body that functions well. You should seek out a balance that emphasizes the latter, rather than the former.
