The Opposing Muscle Groups Workout Routine For Massive Size Gains

arnold flickrIf you’re looking for a great workout routine to pack on muscle as fast and efficiently as possible, you won’t go far wrong with the opposing muscle groups routine.

Also known as agonist/antagonist training, this type of routine was a favorite of Arnold Schwarzenegger (and many of the other 70’s bodybuilders), who always believed that training opposing muscle groups made sense. And you certainly can’t argue with the results it gave him.

So what does an opposing muscle groups routine involve, and what makes it such an effective way to train? In this article I’ll answer those questions and I’ll also give you a sample workout routine that you can use to get started with straight away.

What Is The Opposing Muscle Groups Routine?

As its name suggests, an opposing muscle groups routine is one where antagonistic muscle groups are trained together in the same workout.

So that means chest and back are trained together, quads and hamstrings are trained together, and biceps and triceps are also trained together.

Calves and abdominals are usually trained with quads and hamstrings, and shoulders are normally trained with biceps and triceps.

So that makes for a great three way split routine where chest and back are trained in one workout, legs and abs in another, and shoulders and arms are trained in a third workout.

The three workouts are then alternated over however many weekly training sessions you choose to do.

So if you can only get to the gym three days per week you would simply do each workout once per week on its own set day, e.g. Monday, Wednesday and Friday. This is not the best way to do it however as each body part is only being trained once per week, and as I’ve said before this is not optimal for muscle growth.

So a better way would be to train four days per week, and alternate the workouts over your four training sessions. So you might do Monday, Tuesday, Thursday, Friday, or Monday, Wednesday, Friday, Saturday. It doesn’t matter as long as you never train more than two days in a row.

Or alternatively you could use the rotating five day cycle, where each workout is done over a five day period, i.e. 2 on, 1 off, 1 on, 1 off. This is probably the best way to do it as it means that each body part is being trained once every five days, which is about ideal for the more experienced trainee. It also ensures that you never have to train shoulders and arms the day after chest and back – or vice versa.

Why Use An Opposing Muscle Groups Routine?

By training opposing muscle groups in the same workout you get better intra-workout recovery than you would if you were training related muscle groups, like in the push/pull/legs split.

This means you’ll be able to put maximum effort into each body part; something which may not always be possible when training related muscle groups.

For instance if you are training shoulders after chest, your shoulders will already be pre-fatigued to some extent by your chest work. This does not happen in a routine that focuses on opposing muscle groups.

Another advantage of using an opposing muscle groups split is that it ensures you’re doing roughly equal work for both sides of the body so that you build and/or maintain muscular balance. Muscular imbalances are common amongst gym goers who do too much pressing and not enough pulling, or perhaps too much quad work and not enough hamstring work.

There is one small disadvantage though, and that is that there is more of an overlap between workouts. But this should not be a problem if it’s set up properly, as it’s only an indirect overlap. And, as I’ve said before, some of the smaller body parts (particularly biceps) respond well to more frequent training anyway.

A Sample Opposing Muscle Groups Workout Routine

Here’s a great example of an opposing muscle groups split that’s well structured, properly balanced, and sure to give you exceptional results…

Workout 1 – Chest & Back

Bench Press 3 X 5 – 7
Bent-over Row 3 X 5 – 7
Incline Dumbbell Press 3 X 8 – 10
Pull Ups 3 X 6 – 8
Dumbbell Flyes 2 X 10 – 12
Face Pulls 2 X 10 – 12

Workout 2 – Legs & Abs

Squats 3 X 6 – 8
Romanian Deadlifts 2 X 8 – 10
Leg Press 2 X 10 – 12
Leg Curl 2 X 10 – 12
Calf Raise 4 X 8 – 10
Hanging Leg Raise 2 X 10 – 15

Workout 3 – Shoulders & Arms

Overhead Press 3 X 6 – 8
Side Lateral Raises 2 X 10 – 12
Barbell Curl 3 X 8 – 10
Triceps Pressdowns 3 X 8 – 10
Dumbbell Hammer Curl 2 X 8 – 10
Overhead Triceps Extension 2 X 8 – 10

The sets listed are your work sets. Always make sure you warm up properly before these in order to prepare your body for the heavier work, and to help prevent injury.

Alternating Sets

Another useful aspect of opposing muscle group workouts is that they lend themselves perfectly to doing alternating sets.

Alternating sets, where you alternate back and forth between sets of one exercise and sets of another, are a very time efficient method of training, and they also help you maintain strength between sets more effectively than you would if you were doing straight sets of a single exercise.

So for example you could do a set of bench presses, rest 1.5 – 2.5 minutes, and then do a set of rows. Again rest 1.5 – 2.5 minutes and then do another set of bench presses – and so on.

You’ll note that in the above workouts all the exercises can be paired up in this way, except squats and Romanian deadlifts which should be done as straight sets.

The opposing muscle groups routine is an excellent training method for both intermediate and advanced trainees. But it’s not really a beginners program, and if you are just starting out you’d do better with a full body workout performed three times per week.

Then when you’ve been training a while and have made some good gains, you’ll probably find you’ll make better continued progress if you switch over to doing upper/lower splits.

But at any time past the beginner stage you may find that the opposing muscle groups split suits you better. Or you may wish to alternate upper/lower splits with an opposing muscle groups split in order to experience all the benefits that each has to offer.

Either way the opposing muscle groups workout routine is an extremely effective method of training that is certain to give you exceptional results if you apply yourself to it diligently.

  1. Hi,

    Thanks for providing such an useful information.

    I have been working out since 10 months and I weigh 64 kgs. My body contains lean mass and it seems to me that gaining weight is very hard for me.

    I have read your book titled “The 4 Best WORKOUT ROUTINES To Build Muscle FAST!”, can you please suggest which work out routine from this book should I follow ?

    Thanks and regards,

    • From what you say I’d suggest you do the full body routine and continue with that until your strength gains plateau. Then switch to the upper/lower split. Make sure you eat at a calorie surplus and avoid too much extra strenuous activity in order to gain weight.

      • Thank you very much for your reply. Actually now I am following the workout routine of Mike Mathew, that is “Bigger Leaner Stronger”. But when I came across your workout routines then I realise that I should give a try to your workout routine as they are all based on compound lifts.

        As far my strength is concerned now I can do bench press with 42.5 + 42.5 kgs that is 85 kgs in total for 4 to 5 reps.

        I can do overhead press with 45 kgs in total for 4 to 5 reps.

        Now please suggest still do you think I should do the full body workout or doing full body workout may slow down my recovery process?

        Thanks and regards,

        • When you are working out the weights you are using, don’t forget to add in the weight of the bar. If you are using a 7ft Olympic bar, it weighs 20kg. So that means you’ll be using 105kg in the bench press and 65kg in the overhead press. If you are doing them properly (i.e. bar touches chest in bench press and goes below chin in overhead press) those are decent lifts and you are quite strong. So on that basis you should probably go straight to the upper/lower split. Best of luck.

          • Thank you very much for your help. Your book is better than bigger leaner stronger. I wish it should be in amazon for sale so that maximum people can get benefits from that book.

            Regards,
