Ben Pakulski’s Mass Intentions 40 Inside Out

MI40 stands for Mass Intentions 40, a reference to this particular number as a foundation to all the aspects of the program and to the conscious effort required in performing the exercises. The program is the creation of Ben Pakulski, a world renowned pro-bodybuilder with a degree in Kinesiology and Biomechanics, the science of movement and muscle function, who is also author of the new program MI40X, which you can read a review of here.

With over 14 years of expertise and top achievements in the bodybuilding world, he has developed a training and nutritional system focused on the body as a whole and on the importance of correct exercise execution for anyone willing to build muscle fast, particularly for natural bodybuilder with normal recovery abilities.

The importance of correctly performing exercises for optimal results goes in stark contrast with the common mistakes that, he says, we all have witnessed in the gym now and then. The guy throwing the weight around with excessive poundage in an attempt to convince himself and and onlookers of being stronger than he really is or simply applying the heavier, the better approach in the mistaken belief that heavier weights will lead to bigger muscles.

This approach leads to stagnation and even injury, we have all seen these guys coming in the gym day in, day out for months without a single extra inch to show for while other guys seem to get twice as much results in a short time, and that’s not genetics, but correct approach, he argues

According to Ben, muscles do not “know” pounds but only “feel” torque. It does not matter how many pounds are loaded on a bar, what is important is the way muscles move the bar in a full range of motion under tension, better still, maximal tension.

The techniques Pakulski devised to implement this challenging approach are two: Mass Intentions and Neurological Overload Sets (more on these below). Instead, the number 40 is the constant factor that refers to anything involving this program: 40 seconds to complete a set, 40 seconds of rest, 40 minute workouts, 40 exercises, 40 days program and so on. 4 is also the number of the last drop set in a group of 4 sets.

This means that 40 is not a fancy number trick born out of fantasy, but the net result of years of experience and real life results to support this practical approach.

MI40 Intentions – What Are They?

Time Under Maximal Tension With A Twist

As the name implies, Intentions and Mass Intentions are just that, a unique voluntary and neurological input applied when performing a resistance movement against weights that consists in creating an extra artificial torque in compound movements by pushing outwards on the bar with your hands while pulling and by curling inward on the bar while pushing.

This mean that while you perform lats pull downs, for example, you should consciously push with your hands outwards on the bar while at the same time pulling down as normal. This creates a complete new stress to the muscles, increasing the torque and forcing you to drastically reduce your normal poundage for any given number of reps.

Conversely, while you perform a bench press or an over head press, you should also push inward your hands on the bar while pushing away from your body. Again, this requires a complete adjustment of your normal poundage.

According to Ben, torque and tension through the range of motion are more effective for muscle and strength building that heavier weights thrown around with poor form, in complete contrast to what you often see in the gym.

The whole point of this approach is to throw away your ego and disbelieve the heavier the better approach but focus on quality resistance instead, so as to feel your muscles really working and see them growing. This approach has already worked very well not just for Ben, but also for scores of his customers and friends, first of all world renowned expert and buddy Vince DelMonte.

We think that whatever technique requires movement control and correct execution is more effective for muscle building that ego filled “free weight put shots”, so thumbs up for MI40.

NOS – Neurological Overload Sets For Mass Building

Revisited Drop Sets For Extra Muscle Gain

The second key technique used in the MI40 program for optimal muscle stress and testosterone and growth hormone, hence muscle growth, is a revisited version of the good old drop sets repackaged in a more scientific way.

How many times we have walked out of a gym feeling that we did not really gave everything we had, or that our typical straight set workout sure challenged our muscle to some extent, but not really that hard.

This is because neurological adjustment sets in, the endocrine system is not stimulated enough to produce extra testosterone and muscle growth, our muscles are not really challenged and stagnation sets in.

The Neurological Overload Set, a drop set performed as the fourth final set of a group of 4 sets of a given exercise, pushes the muscles to a level of complete failure way beyond the limits of a mere straight set. Total failure is achieved by dropping the poundage 20% off the previous poundage every subsequent drop for a total of 4 sets without rest between them.

The repetitions are also performed in a 4010 fashion, meaning 4 seconds in negative and 1 second in positive without stopping at the top or bottom, bringing every rep up to 5 seconds and a set of 8 up to 40 seconds.

Every subsequent 20% decrease in weight should be performed as strictly as possible for as many reps you can get and even performing half reps (the lower part of the range with the muscle fully stretched) until the next drop in allowed.

This is a drastically hard technique that, according to the author, is guaranteed to kick endocrine system, testosterone, growth hormone into overdrive and muscle gain.

The program is also structured around variation. No workout is the same so as to keep you motivated and your muscles challenged even within the foundation basics of time under maximal tension, torque intentions and extended drop sets for neurological overload.

  1. The 40 Day Mass Intelligenge Training Manual: a 33 page PDF manual with all the basics of Ben Pakulski’s training system and the foundations of his workout methods, where he explains the concepts of Time Under Maximal Tension, the Intentions, which is the deliberate manipulation of the torque needed to perform any lift by adding extra inward force in pushing movements and outward force in pulling movements. And of course, NOS, which stands for Neurological Overload Sets, an updated and more accurate version of the good old drop sets.
  2. The 40 Day Mass Consumption Nutrition Manual: this is a complete 53 page guide to nutrition for optimal muscle growth and fat loss structured in a 3 phase way. Phase 1, Intra Workout Nutrition, describes what you should eat during the workouts. Phase 2 is split in 2 main components, pre workout and post workout nutrition.

Does MI40 Work? Who Is It For?

Is It And Effective Muscle Building Program?

Ben Pakulski’s MI40 program is a well structures muscle building, workout and nutritional regime that requires commitment and discipline. While the workouts last only 40 minutes, they are very demanding not just on your muscles but also on your nervous system.

The combination of high intensity techniques like NOS (drop sets) and Intentions (additional inward and outward torque with your hands on the bar on a given exercise) are designed to exert continuous maximal tension on your muscles in a full range of motion and to exhaust them to utter failure, the like of which is not possible to achieve with regular, straight sets.

Not only does this mean that this program can be unusually hard even on someone who regularly works out, but it can be a real challenge for beginners. In our view, IM40, though sound and valid, takes for granted that you should have some sort of workout experience and have already gone through regular training routines to be able to withstand it.

We also think that the implementation of these techniques could be too much too handle for some people, not just beginners. To control the bar pushing outward or inward while also pulling or pushing in a controlled way for a given tempo sounds a bit too much to control.

The mental effort required to perform these extra tasks while pushing or pulling could detract from correct weight progression because you have no way to exactly know how much torque/resistance you apply inward or outward on the bar while performing the exercises, it can fluctuate.

By contrast, straight, regular movements never lie. You know that if you have a 200 pound bar to push up or pull down, it is 200 pounds. Always. You know that if you go to 210 pounds you are getting stronger. But pushing out or pulling in, you do not really know where you are on progression, at least to start with.

We think that for building an accurate feel for the extra stress involved and get the most out of these techniques takes time and effort and that if you are a beginner you should do a beginner program first to prepare yourself for the high intensity techniques described above.

But if you are an advanced or at least intermediate bodybuilder you have better chances to adjust to these extra neurological and muscular stresses. In any case, NOS and Intentions require a drastic reduction on the usual poundage normally used.

The workouts too, while being just 40 minutes, are based on a 5 a week split routine. This leaves little room to flexibility. You have to really plan you weekly activities well in advance, or else if you skip a workout you’ll have some body parts lagging behind others on the schedule.

Having said all this, MI40 is an effective program for intermediate to advanced bodybuilders for extra muscle gains. There are tons of testimonials with graphic before and after pictures that leave no room for doubt. Ben Pakulski himself is the best embodiment of his own expertise and knowledge.

MI40 Pros And Cons

What’s The Bottom Line?

Here is our opinion on this program:


  1. Created by an author and professional top bodybuilder with 14 years of experience on the field and a degree in kinesiology and biomechanics. Ben knows everything on how to challenge muscles for maximal mass gain in the shortest time.
  2. Very comprehensive program. It comes in 8 parts in PDF, Video and Audio formats covering everything from exercise execution, workout plans, nutrition, supplements, you name it.
  3. Effective. There are tons of testimonials to support this program effectiveness, including Ben himself and buddy Vince DelMonte.
  4. It works both for men and women. Many females also enjoy excellent results.
  5. It is accurate. Nothing is left to chance, it is articulate but also simple because it revolves around the “magical” number 40 that leaves little room for error, from exercises to set time, rest time, number of days to complete the program, number of exercises and so on.
  6. It is not just theory but also very much hands on and practical, the videos and the pictures in the execution manual are crystal clear.
  7. It comes with a 60 day money back guarantee.


  1. The program is not suitable for beginners. The techniques involved are really challenging and in our view it requires a solid training history first.
  2. It lasts for 40 days, but while results are almost guaranteed, providing you work hard, it is not very flexible because it is structured on a 5days/week split routine. You really have to commit yourself before you start it.

Final Verdict: MI40 is a program designed to achieve maximal muscle gain in the shortest possible time with the use of high intensity techniques like NOS and Intentions that require commitment and a desire to break through the “comfort zone” of regular straight set workouts.

MI40 is therefore more suitable to someone with experience in bodybuilding or weight training rather than a beginner. However, it pays off big time for those who use it with above average muscle gains and fat loss, helping cut through plateaus and stagnation.
