At 17 you should be able to progress on full body routines 3 times per week. You could vary this over 2 workouts, e.g. week 1 A-B-A; week 2 B-A-B, etc. You seem switched on regarding the big compounds, e.g. squat, deadlift, dips, chins, etc. I wouldn't over-complicate things with elaborate splits unless you are extremely active outside the gym.
alright. So At 17 I would make more progress on a total body training rather than on a split? When do you think I should addopt splits then? I can dedicate up to 4 days of training per week.
How does this full body split look?
Squat 5 x 5 DeadLift 5 x 5 Some type of Bench Press 5 x 5 Some compound rowing movement 5 x 5 Seated Shoulder Press 5 x 5 Bicep Curl 5 x 8 Dips 5 x 8 Weighed Crunches 5 x 15
Squats 5 x 10 Deadlift 5 x 10 Some type of Bench Press 5 x 10 Some compound rowing movement 5 x 10 Seated Shoulder press 5 x 10 Isolation exercise 1 5 x 10 Isolation exercise 2 5 x 10 Hyper Extensions 5 x 15
you could do a three day split, a four day split, three day full body or four day full body. it really doesnt matter... most people like to hit each muscle group twice a week though. if 4 days a week are available to you i would suggest going with the traditional BB'ers split (hitting each muscle group twice a week).
You said that you over did the last year of training. In my opinion, this plan is WAY too much volume. I really like the principles of the 5/3/1 program because it presents a workout that has you emphasizing the core lifts (squat, DL, bench, overhead press) followed by 2-3 exercises that are used to support everything else. You may want to look into that program for guidance.
As a side note, I know that EVERYONE is told this when they begin training (I was) and that you most likely won't listen, but you need to stick to compound movements for now. Isolation isn't of any great importance yet. You need to learn how to train before you can learn how to be a top notch bodybuilder.
When I started training, I did curls and skull crushers and the like for arms. Six months later, I had minimal results, so I dropped them and started to work up to heavy weighted dips and chin-ups, and now my arms are much bigger, and my strength in other lifts went up as well. Plus, having a few 45 pound plates between your legs and doing chins makes you feel like a true "badass."
Hit up CC's How do you train thread... he's got all sorts of splits listed for various members. Most of the splits are listed in the middle-to-latter part of the thread, but you should definitely be able to find one which suits your needs (3-6 days per week). Either do that or visit Iron Addicts -> Beginners -> Beginners Routine to get a split or follow Wendler's 531 or BBB.
Also, look into the Best of T-Nation thread for some very valuable info from experienced members. Whatever you do just pick one split, stick with it, and get progressively stronger on the exercises over months to years. Make small adjustments over time only when you are not getting stronger on a particular exercise.
EDIT: props to the mods for moving this to the beginners forum. :b
NO ABSOLUTELY NOT(see blufinga's avatar above)! that is not for beginners! Seriously... its a good template but do not train that style. use the base of the template and do like 3x8's or whatever. DC is for experienced lifters ONLY
One year lifting experience isn't typically enough to prime you for DC. It takes more than drive and enthusiasm - you really need to develop mind muscle connection. Additionally, you should probably make sure that you're completely done growing. I know that's not what you want to hear but I think that's the best advice there is to make you grow.
