The Lifestyle That Changed Nicholas Galitzine’s Body For Masters of the Universe

Many actors have to undergo intense physical transformations in order to portray their characters with accuracy.  The same can be said for Nicholas Galitzine in the five month stint preparing for his role of He-Man in Masters of the Universe.  He-Man is famously huge, and his costume reveals his extraordinarily defined figure.  Galitzine had only a few months to take his previously athletic frame and convert it into the hulking mass that is He-Man.  How did he accomplish this and how can the individual athlete pack on serious muscle in a shortened time frame?

Intense Weightlifting

Obviously, the key to building muscle mass is intense weightlifting.  All other forms of exercise are beneficial for one’s mind and heart, but strength training is the only activity that will generate the muscle mass that many seek.  It is not one gym session that accomplishes this, rather, it is consistency over time that builds one’s lean mass.

Hitting the Gym Everyday

Galitzine did strength training everyday for five months in order to transform his lean physique into something more hero-like.  Strength training daily encourages one’s lean mass to be in a near constant state of synthesis, hourly repairing and rejuvenating new muscle tissue.  Daily strength training for Galitzine allowed him to hit every body part at least twice per week, maximizing his strength output.

Three Hour Sessions

Galitzine reported that his daily gym sessions lasted three hours each!  If this is attainable for the average athlete, then making the most of one’s time in this way will yield big results.  However, many individuals are not able to spend three hours per day lifting weights.  Even if one is not able to spend three hours lifting weights like Nicholas Galitzine, one hour per day is sufficient for adequate muscle growth.

Consistency Yielding Results

One may not be able to lift weight every day per week (and often one should not, as rest days are essential for muscle care and recovery).  The athlete should not feel discouraged that he cannot hit the gym at the same frequency as Galitzine, but the point remains the same: consistency yields results.  Even if one is only able to go to the gym three times, as long as these three days are completed every week, muscle mass will be built.

Burning Calories Throughout the Day

A necessary part of health and wellness is cardiovascular exercise alongside strength training.  If one only does strength training without cardio, one will have excess fat and will not have the healthiest heart.  Galitzine performed cardio between scenes, as well as during the stunt training when he was not lifting weights.  Additionally, Galitzine moved and burned many calories while shooting the different scenes.  Constant movement and dedicated cardio sessions kept He-Man lean while packing on serious muscle.

Cardio Between Scenes

Galitzine reported that between shooting scenes, his trainer had him doing rounds on an assault bike.  The constant HIIT-like cardio kept extra fat off of his body, while keeping his muscles pumped for shooting scenes.  The same principle applies for the everyday warrior: keep moving!  Constant movement, whether it be cleaning, walking, standing or fidgeting will burn extra calories each day, fighting fat gain that accompanies seasons of bulking.

Stunt Training

A necessary part of preparation for Masters of the Universe was stunt training.  Galitzine performed many of his own stunts, including the many fight scenes.  This MMA-style training offered Galitzine additional cardio sessions alongside his usual workouts.  Having dedicated time to perform cardiovascular activities is essential for heart health as one packs on muscle mass.

Constantly Moving During Scenes

The scenes that were filmed included activity and consistent movement.  This is similar to one living an active lifestyle throughout the day.  If one works at an office, purchasing a standing desk and taking one’s breaks to go on walks are easy ways to increase movement.  If one works from home, the same advice applies; for one who works a physically demanding job, including cardio sessions throughout the week is still necessary.

Diet

When one’s goal is to pack on serious amounts of muscle, dialing in one’s diet is absolutely essential.  One can train extremely hard, but if one is not eating enough quality food, one’s muscle building progress will stall.  Galitzine had his diet calculated to provide the most muscle synthesis; one must evaluate how to eat when desiring to build muscle while burning many calories.

5,000 Calories Per Day

To support the daily strength training, consistent cardio and constant movement while filming Masters of the Universe, Galitzine reported that he had to consume 5,000 calories per day.  Odds are, the everyday athlete is not currently in a state that 5,000 calories are necessary.  One must calculate how many calories to eat in a surplus in order to pack on as much muscle as possible.

How To Build Muscle with Constant Activity

Whether one is working a physical job or is able to engage in constant activity while working in other occupations, eating enough calories is essential to build muscle mass.  Often, athletes will work exceptionally hard yet see little progress.  This is frequently due to not eating in adequate quantities for muscle growth and recovery.  Galitzine had to eat 5,000 calories per day to build muscle based on his activity levels; use a Total Daily Energy Expenditure (TDEE) calculator online to find out how many calories one must personally consume in a day to maintain, lose or add weight.

Bulking vs. Cutting

During the five months of Galitzine’s preparation for his role, he was in a state of bulking.  When bulking, one will put on both fat and muscle.  Galitzine’s prerogative was not to be cutting weight, as that would decrease visible muscle size and he would have lost the water retention that gave his lean mass such definition.  Whichever one’s goal is, one’s visible mass will fluctuate depending on the amount of food consumed.

Fighting Fatigue

Through shooting active movie scenes, intense weight training and cardio sessions in between both, Galitzine was constantly working his body.  Throughout anyone’s strength training and cardio sessions, muscular wear and tear is part of the game.  This can be mitigated through proper stretching and care for one’s body, including obtaining enough sleep to recover.  Without these preventative and responsive actions, Galitzine would not have been able to sustain the rigorous training that he chose.

Wear and Tear is Real

Through intense strength training and cardio throughout the day, He-Man’s body experienced much wear and tear.  This remains true for all committed athletes.  As one works out consistently, the body will become weakened.  The muscle synthesis process is what remedies weakened muscles, however, the athlete may benefit from a few extra rest days each month.  One’s joints and tendons will benefit from extra rest when training has been intense and consistent for a long period of time.

Proper Stretching and Muscle Care

The simplicity of stretching and warming up is often the reason why this practice is so frequently skipped.  Preparing one’s body for exercise will allow for less injuries and will also lend itself to post-workout recovery.  Stretching after one’s training session and tending to any minor injuries or discomforts will serve one’s longevity and will keep one’s body in tiptop shape!

Obtaining Adequate Sleep

Many individuals obtain poor sleep, and then wonder why they feel so tired each day.  Especially if one is serious about training, sleep is critical for muscle synthesis, as recovery occurs at the highest rate when the individual is asleep.  Giving oneself adequate sleep allows for more energy during the day and during future workouts.

How to Put on Muscle Like He-Man

Through Galitzine’s intense training and diet, he transformed his lean body into that which resembles an action hero.  This was only accomplished through a consistent strength training system alongside a diet that matched his energy expenditure.  He also had to be mindful of cutting down fat so as to appear more toned.  The delicate balance between these three facets are what creates a hero-like body.

Consistent Weight Training Program

The individual will only be able to put on muscle mass when adhering to a strict weight training program.  Going to the gym and sporadically doing random exercises will not yield any desired results.  Find one of the countless resources online that can provide one with a detailed, day-to-day plan for intentional weight lifting.

Consuming Enough Food

While one is working out with consistency and drive, adequate amounts of food must be consumed.  The body needs enough protein and calories to create new muscle mass.  The body will feel constantly drained and tired if not given enough food with which to synthesize new muscle.  When the athlete eats to build muscle, fat will develop as well, necessitating fat-burning measures.

Cutting the Fat

To achieve a He-Man-esque figure, one must cut the excess fat so as to display lean mass.  Cutting involves eating slightly below what one needs to consume each day, while prioritizing cardio alongside consistent strength training.  Burning extra calories through cardio will encourage one’s body to shed the fat that is visibly blocking one’s dream physique.

Essential Amino Acid Supplementation for Intense Transformations

Throughout the process of strength training and cardio, the body must have enough amino acids for recovery.  However, one often will not be able to obtain enough amino acids through food for optimal recovery.  Essential Amino Acid supplementation will keep one feeling energized.  With electrolyte consumption alongside EAAs, the athlete’s muscles will avoid cramping and have energy for each training session.

EAAs for Muscle Recovery

Protein consists of amino acids, but protein is not always consumed in ratios that provide the most efficient recovery.  This provides the need for supplementing with Essential Amino Acids.  When the body has extra amino acids in the system, muscle recovery will be quickened and the athlete will have more strength during workouts.

The Importance of Minimizing Fatigue

If the body has enough amino acids to appropriately care for worn lean tissue, one will have more perceived energy throughout the day.  This spills over into one’s workouts, providing enough energy for the athlete to perform each day.  Heightened fatigue during workouts increases injury risk, necessitating the need for consistent amino acid supplementation.

Added Electrolytes

Many athletes wish to add electrolytes to their supplement routine due to its benefit for muscle contraction and hydration.  Galitzine needed to stay hydrated throughout each day due to his intense workouts, cardio sessions and work environment.  For the individual wanting to look like He-Man, taking electrolytes will facilitate more energized workout sessions and less fatigue in recovery.

Frequently Asked Questions (FAQs)

How do I know what is a sustainable amount of exercise?

If one’s body is not overly fatigued and one’s tendons are free from pain and soreness, then one’s current workout routine is likely sufficient.  Keep pushing oneself to harder goals, but do so in a way that keeps the body from unnecessary fatigue and pain.

How can I burn more calories throughout the day?

To burn more calories during each day, one must increase hourly movement.  If one works a sedentary job, this can look like using a standing desk and taking a five minute walk each hour.  At home, one can burn more calories by cleaning instead of sitting for hours, utilizing a walking pad when watching TV or walking through neighborhoods or parks during the evening.

What if my appetite does not match my activity levels?

Many struggle to eat enough food to supply current activity levels.  If one is struggling to consume enough protein, taking an Essential Amino Acid supplement like our Muscle Synthesis Activator will support the protein that one has already consumed.

How long does it take to feel the effects of Essential Amino Acid supplementation?

Most users of our Muscle Synthesis Activator experience less soreness and more energy within seven to 10 days.  Some have even reported feeling less sore after the first day!

Does Oh!mino have other supplements that can assist in my goals?

Yes!  In the effort to continue building muscle volume, one should inspect our dual-form Creatine Complex.  If one is desiring to increase their muscle pump and endurance while reducing inflammation, our Nitric Oxide Booster is the perfect assistant.
