Training Biceps & Triceps on the Same Day: What you need to know

by Mike

Hello, fitness enthusiasts!

If you’ve come to this post wondering if you should train your biceps and triceps on the same day, let me tell you that you’re in the right place!

There’s a lot of conflicting opinions on the internet about getting bigger guns, but we’re here to help you out! Keep reading to find out how to maximize your gains the right way.

A Little Anatomy of the Biceps & Triceps

To benefit from the targeted exercises, you need to understand a bit about the functional anatomy of these two muscle groups.

The triceps is the muscle located on the back of your upper arm. It has three heads (hence “tri”-ceps) that originate from your shoulder blade, and insert somewhere near your elbow. Triceps work to extend your elbow. In flexing the shoulder or lifting overhead, we recruit the long head of triceps.

The biceps is the muscle located on the front of your upper arm. It has, you guessed it – two heads. Incline curl variants or extension of your shoulder focuses on the long head of the biceps and moving your elbows in front of your body (preacher curl variants) focus on the short head.

Biceps and Triceps are called agonists and antagonists because their functions are essentially opposites of one other. The biceps flexes, whereas the triceps extends your arm.

Should You Train Biceps & Triceps on the Same Day?

Is it okay if I work these two muscles on the same day?

In one word – yes.

Most professional weightlifters and fitness coaches prefer “supersets” which means doing a set for biceps, immediately followed by a set for triceps. For example, hitting a set of heavy barbell curls and then super-setting with the seated tricep press would be a great alternating workout for the bi’s and tri’s.

While this yields good results, you have to keep in mind that they essentially work opposite to each other.

Training them together would be like driving a car forward, and then backwards, over and over.. This is supported by “Reciprocal Inhibition” which means that when one group of muscles is activated, the opposing set of muscles are shut off.

If I train them on the same day:

  1. What muscle should I work on first?
    If you’ve decided to work these two on the same day, doing Triceps before the Biceps is a better idea.
  2. How many sets should I perform?
    12 to 15 sets for each muscle group are enough if you are training them on the same day.
  3. How many rest days should I take between each workout?
    Depending on how many days you can go to the gym, you should aim to keep at least 48 hours between each workout if you’re doing triceps and biceps on the same day.
  4. Track your progress

What Should I Do to Get Maximum Muscle Growth from My Biceps & Triceps?

training biceps with triceps

To get maximum muscle growth, you have two options. The first is to couple biceps with your back, and triceps with your chest and shoulders.

Why? Because the biceps are recruited in the “pulling” movements of the back exercises, and it makes sense to train it on the same day. A similar logic works for the triceps and pushing exercises for the chest and shoulder.

You can also train biceps with your pushing muscles, i.e. chest and shoulders, and triceps with your pulling muscles, i.e. back. The logic here is that by the time you are done with the pulling exercises, your biceps have already finished training during these pulling movements, and will be pre-exhausted. So now, if you want to focus on your triceps, they would still be fresh.

You also need to make sure you are getting enough nutrition and protein in to fuel your recovery. You can supplement with a meal replacement shake like kachava or some other protein powder to increase your protein intake.
