Workout Description

Last month, we shared with you a beginner version of High Intensity Training.

HIT is a style of training that involves a single work set to ultimate failure and places emphasis on both the preparation for that work set as well as the recovery after training.

If you tried it, we hope you saw gains as a result.

Now we’re going to step it up with both 4 and 5 day versions of HIT.

As you will see, the biceps and triceps are what differentiates these splits from the three day versions.

We’ll go over why these splits are designed the way they are and give you sample workouts so you can try HIT out for yourself and see how you can improve.

Before we do, there is another twist that is included here.

Intensity Boosters

Most of you are likely familiar with these but we should cover them anyway for those who are new to the iron game. There are ways to extend a set so you can do more work and really exhaust the muscles you’re training. They are known as intensity boosters and they are properly called that here since we are working with high levels of intensity.

For the purposes of this program, you should get to know these three boosters because you’ll be using them often.

Drop Sets

Upon failure with a traditional set, you would normally rack or release the weight. Drop sets require you to continue by lowering the weight you’re using. So if you’re using 200 pounds and reach failure, you would drop to something like 150 or 160 and try to get more reps.

This is taking a normal set beyond failure and maximizing the damage being done to the muscle. Why put yourself through this kind of agony? Because when we recover and eat, there will be more opportunity for growth.

The amount you drop can be up to you based on how you feel.

Rest Pause Sets

Rest-pause training calls for you to extend your set another way. When you reach failure, you would count out 10-15 seconds. After that brief break, you resume your set with the weight you’re using to try to get a few more reps.

If you use 100 pounds and get 10 reps, you would rest for 10-15 seconds and perhaps get 4 more before stopping. That’s 14 reps with what you would normally do for 10. Each of those reps can make a profound difference.

Forced Reps

You MUST use a spotter or partner for this one. Just because you reach failure lifting the weight doesn’t necessarily mean you reached total failure.

With forced reps, your spotter would assist you in lifting the weight but you would be responsible for lowering it under control to the bottom. The spotter repeats this until you can no longer control the weight at all. This is total failure.

A Reminder of Rest

There won’t be recommendations of rest between sets because that’s up to you as the athlete. I would suggest no more than three minutes because you want to stay warm.

If you feel like you can go after 1 minute, great. If you need three, take it. Just make sure you’re ready to go when it comes time to lift.

4 Day HIT MASS Split

For the four day split, we have separated the muscle groups so you’re training no more than two a day. You’ll notice biceps are paired with chest and triceps are with back. This is intentional so you have the most opportunity to train the bis and tris effectively.

If you go all out on chest like you should, then your triceps will be doing work as well. Because of this, it will be harder to maximize the potential of triceps work. So instead, we would target biceps, a pulling muscle, which would be fresh and prepared to work.

Conversely, training biceps after they’ve assisted your back wouldn’t be as effective so instead we would match triceps up with back. While this isn’t a replica of his workouts, this split was made famous by 6 time Mr. Olympia Dorian Yates.

5 Day Split

Let’s face it. Most people who train love arm day. So we also have a 5 day split that includes a day only for the biceps and triceps.

Since this is the only training you would be doing for your arms, you have to make sure each rep counts.

Is the leg raise supposed to be in shoulder day? Also, I am a UX Consultant so I have to let you know that link goes to a leg curl too.

If you've been doing this for a while, and feel you need it, then yes. If you're new to this, then I suggest sticking with it as recommended because you may find what is on the program is enough.

Any light activity that isn't strenuous and promotes recovery. My go to forms are walks and yoga.

Hi Marley,

Each program is a 6 week program. So you'll do the 4 days a week for 6 weeks then the 5 days a week for 6 weeks.

But before you start, be sure to kick things off with the 3 days per week version of this workout here: https://www.muscleandstrength.com/workouts/hit-mass-3-day-split

Hope this helps!

Body part split workouts aren't really that great. Your muscles get essentially 6 days off until you hit them again, and in reality they only need 48-72 hours of recovery. If you look at any scientific studies you'll find that their research supports increased training frequency because it leads to faster results. Training a muscle twice per week with less volume each session is far superior to training a muscle once per week using a ridiculous amount of sets. If you wait that long to train the muscle again, you will actually see a decrease in performance because the certain muscle group hasn't had a stimulus to grow for 6 days. In addition, when you train say back, shoulders, then arms on consecutive days that is overdoing it on your elbow joints, shoulder girdle and the flexor and extensor tendons. So, I don't agree with this or any other body part split programs that muscle and strength posts. An upper/lower split is far superior because you train each muscle group twice per week, don't overuse your tendons and joints and also you still get adequate recovery time.

Hi Jack,

I agree with a lot of the points you've made here. Upper/lower splits have proven to be more beneficial (especially in naturals and those seeking to improve performance).

But, we shouldn't completely take away the benefits that body part splits have to offer. They can and do provide people with results. Could they see better results by training more frequently? Sure. Will they not see results at all by performing a body part split? Of course they will see some sort of result. Any form of training that promotes adaptation will cause a trainee to see results.

The key factor you're missing in your comment is enjoyment. Some people simply enjoy body part splits. And as we all know, enjoyment is the number one predictor of long term fitness success.

The 3 day split can be done 5 or 6 days per week to increase frequency. The reduced volume makes it ideal. I'm on 3 day split M-F hitting each body part every 3-5 days and 5 times every 3 weeks.

Can you explain why it says "Yes, its only 4 work sets per muscle"? I see that there are 3-4 intensity techniques per muscle but are the other sets not work sets? Are we only concerned with the last set and the first 2 sets - 15, 10 reps are just warm up sets? What about the exercises that dont have an intensity technique after the 3 sets are completed? Thanks!
