Is High-Intensity Training (HIT) Good At Building Muscle? – SET FOR SET

Though Excessive-Depth Coaching (HIT) has been utilized in bodybuilding for no less than the previous 50 years, it is solely lately turn into widespread in mainstream health. Often sitting on the fringes of lifting, its methodology has begun to be taken extra critically. 

It appears to instantly oppose conventional bodybuilding, because it emphasizes the depth of coaching reasonably than excessive quantity. As such, many bodybuilders used to excessive quantity are suspicious; can HIT coaching truly construct muscle?

This doubt often stems from misconceptions and exaggerated claims; this text will break it down and present that HIT coaching is usually a viable choice for constructing muscle.

What Is HIT Coaching?

Excessive-Depth Coaching (HIT) is a method of bodybuilding, or muscle constructing, in distinction to conventional bodybuilding. The foundational distinction is that it views effort as the first driver of muscle progress, reasonably than quantity (Schoenfeld et al., 2017).

It was made well-known by bodybuilders corresponding to;

• Dorian Yates
• Mike Mentzer
• Dante Trudell

All 3 practiced barely totally different coaching kinds, however the basis was the identical. In a nutshell, you could possibly describe a HIT coaching program as;

• <10 Weekly Working Units Per Muscle Group 
• 1-2 Units Per Train
• Prioritize Compound Actions
• Usually Decrease Coaching Frequency
• Depth is prioritized, and units are taken to failure or previous failure.
• Use of particular units

Does HIT Coaching Really Construct Muscle?

Sure.

Whereas HIT can look fairly totally different on paper in comparison with conventional bodybuilding, we underestimate how highly effective resistance coaching might be.

In truth, the sooner units are extra highly effective.

We have spoken about this study from Pelland et al (2025) very often, however we predict it does a fantastic job illustrating this. These researchers regarded on the dose-response that weekly set quantity had on muscle hypertrophy and power beneficial properties.

They found:

• Minimal Efficient Dose to detect hypertrophy was 4 working units per week. 
• Highest Effectivity was 5-10 working units per week.
• Intermediate Effectivity was 11-18 working units per week.
• Dose Response as much as 42 working units per week
• Diminished Returns after 18 working units per week

This means 5-10 weekly working units gave the best return.  They discovered that doing extra units led to larger progress, however the return per set decreased with every extra set.

In different phrases, all you want is 5-10 working units to construct muscle, and HIT does this.

Misconceptions With HIT Coaching

HIT coaching is often surrounded by excessive beliefs and practices as a result of that is what’s on social media. This can result in quite a few misconceptions that we’ll focus on now.

HIT Coaching Exists On A Spectrum

Many individuals wrongfully assume that HIT coaching is a selected coaching protocol. It is not.

Quite, it is a coaching methodology with practitioners existing on a spectrum.

• Mike Mentzer, who would solely prepare as soon as each 5 days. 
• Dorian Yates, who routinely used 8-10 working units every week.
• Lifters who use a hybrid of HIT methodology inside their coaching

We at SET FOR SET strongly imagine all methodologies have advantages, and the very best general coaching program often attracts from a number of methodologies.

HIT Coaching Does Not Imply Minimalist Coaching

A typical false impression is that HIT is solely a minimalist type of bodybuilding. Whereas it usually includes decrease quantity and shorter exercises, that does not make it minimalist.

Minimalist Coaching is an method centered on lowering time and complexity within the gymnasium.

HIT Coaching is a strategy constructed on the concept depth is the first driver of muscle progress.

In different phrases, HIT is about the way you prepare, whereas minimalist coaching is about how a lot you prepare.

With that mentioned, HIT methodology is a good choice for minimalist coaching.

In fact, SFS has actually just released a HIT Minimalist Workout Program here!

HIIT Coaching Does Not Imply 1 Set A Week

Someplace alongside the road, the idea of building muscle with 1 set a week was born.

This is not true. Whereas there are some bodybuilders who use these extremes, it is not the norm.

This can be like saying lifters who imagine quantity is crucial variable use 25+ units. In fact, some try this, nevertheless it’s uncommon.

Once more, HIIT coaching is all about coaching every set with maximal depth, not performing the least doable.

HIIT Coaching Makes use of Extra Quantity Than Claimed

You will usually hear some bodybuilders who use HIT declare they use 8 working units. Nonetheless, after we have a look at their program, we notice that is not fairly correct.

This is as a result of most well-liked use of Relaxation-Pause. Rest-Pause training is a kind of particular set frequent in HIT coaching that permits trainees to coach previous failure.

It is carried out by bringing a set to failure, taking a mini-rest, and performing one other mini-set. This is often carried out 2-4 instances.

So let’s examine how this seems within the gymnasium. As an instance you are utilizing 2X8 for an train.

• Set 1: 8 Reps
• Set 2: 8 Reps
• Relaxation 20s
• Mini-Set: 3 reps
• Relaxation 20s
• Mini-Set: 2 reps
• Relaxation 20s
• Mini-Set: 2 reps

A trainee will often declare they only carry out 2 units with some rest-pause. Nonetheless, as a substitute of counting units, let’s rely reps, and we get 23 reps. That is principally 3 units.

So in the event you did this for 4 workouts, you did not carry out 8 units; you carried out 12 units.

Remember that not all lifters use rest-pause on each train, however you get the concept.

Remaining Say: HIT Coaching Undoubtedly Builds Muscle When Carried out Proper

As we noticed, 5-10 weekly units are essentially the most environment friendly coaching quantity for constructing muscle. For the reason that overwhelming majority of HIT coaching plans have you ever do that, there needs to be no query.

With that mentioned, for many trainees, we predict following these rules can maximize their HIT coaching.

• Follow 8-12 weekly units. Possibly you’ll be able to construct muscle with 5 units, however 8-12 units can undoubtedly construct muscle and finally do not take far more time.
• We expect Relaxation-Pause is a good technique. Not simply to extend depth but in addition to extend quantity.
• Use 2 units + Relaxation-Pause for major compound workouts.
• Use 1 set + Relaxation-Pause for smaller accent work and isolations.

SFS has launched its personal model of HIT coaching. 

• Makes use of the first rules of HIT
• Stays on the higher finish of HIT quantity (10 units)
• Beneficiant use of Relaxation-Pause coaching 
• Structured train swaps to make sure regular progress

In the event you’ve questioned about HIT coaching however aren’t certain concerning the ultra-low quantity some applications present, SFS HIT Coaching is an superior selection.
