Im very new at lifting, but im catching on quitefast (sink or swim) I wanted to know if I should mixup isolation excercises with compound excercises each week or if I should do a week of isolation and then a week of compound.

Whats the most effective way?

I have been making the mistake of only doing isolation excersices, only becuase I didnt know any better and I injured my shoulder last night lifting more weight than my shoulder could take (everything else felt great) so I have been neglecting some serious area of my body to say the least.

I need to make sure this doesnt happen again by training all aspects of my body instead of just one area.

I do a bi/back, tri/chest and legs/shoulder split mon/weds/fri

anyone have any advice?

Thanks

If you are just starting out lifting and don't have a lot of ewel-developed muscle mass now, some would argue that you don't need to/shouldn't do isolation work like curls. I've done compound-only workouts and seen OK gains.

Your split is, however, typical.

I'm sure somebody will come along with more experience.

What exercise caused injury, how did it happen? A mix of compound and isolation with compounds in majority. But all should be done in proper form and at a smooth, controllable speed.

Bah, was pretty stupid to be honest.

I workout at a very crowded gym accross the street from my office and I normally do dumbell workouts for my chest, flat press, incline, ect. but the weights I needed were all being used and I had stood around long enough to become irritated. I headed over to the seated press machine and checked my prior max weight and decided it had been a couple of weeks since I reached that weight and I would bump it up a couple notches.

1st rep; great, 2nd rep; shoulder didnt feel right so I did what any real red blooded american would do.. ANOTHER rep! :tu: 3rd rep, my right shoulder gave out mid rep.

I found a single dumbell at a warmup weight and did a couple of reps to stretch my shoulder and its not good. not bad mind you, but not good.

My right bicep measures 15 1/2'' (left is alittle lower) and I was told I should be doing isolation (not knowing what that meant) I just looked around at all the lifters and said, "i can do that one!" :D

well, after doing some research, they were all isolation excercises which lead me to the question.

Im built pretty well, played football in highschool and lifted, but without a real plan so im not too terribly small, but have lots of room for improvement.

You should have some criteria for "bumping it up a couple of notches", Whatever that is. It must have been alot to make shoulder give out after 3 reps. Structure in workouts pays off.
