Strength Training Modalities: 3 Types of Strength

Different muscular strength modalities require different types of strength training.

I transform human beings for a living. I make them more muscular and way stronger. My clientele is largely elite athletes and elite military. Pros seek me out to get my advice on how to get stronger and how to become more muscular. Together we riddle out how best to improve on their already otherworldly physique and performance. How do you get results for someone already at 100% of their potential? Let’s explore the three muscular strength training modalities: absolute strength, explosive strength, and sustained strength.

A lot of what I do involves reintroducing these athletic sophisticates to some purposefully unsophisticated ultra-basics; throwback techniques and tactics, the kind a lot of them used getting started at the beginning of their career. Over time those super effective Simple Simon tactics were discarded, replaced by ever-more modern training evolutions.

I take them back to their training roots and invariably some variant of this purposefully primitive simplistic yet sophisticated approach unsticks the progress log jam. Simpler does not mean easier: our method is powered by intensity; intensity, degree of effort, is the force multiplier. Put differently, our short strength training sessions are so intense and physically demanding that they need to be infrequent.

The core tenants of our minimalistic strength training approach were developed by our world champion mentors in pursuit of world records in the world’s strongest sport, powerlifting. Our methods are, coincidentally, extremely time efficient. Our approach was not designed to be short, insofar as session duration, it just turned out that way. There is an inverse relationship between training intensity, session length and training volume. The degree of effort exerted in one of our strength training sessions requires time for traumatized muscle tissue to heal, repair and grow. Do not repeat that workout until fully healed and recovered.

Strength Training Technology and the Racecar Analogy

Our strength-training approach is analogous to racecar technology and how racecar technology filters down to passenger cars. Nowadays it is routine for a 2-liter, 121 cubic inches, turbocharged engine to put out 300 horsepower. When I was growing up it took a 375 cubic inch engine to generate 300 horsepower. Our current technological efficiency, the same power from an engine one-third the size, comes directly from the first wave of turbocharged Formula 1 engines introduced in the 1980s. That ancient race technology birthed today’s super-powerful super-efficient passenger car engines.

Our muscular strength technology, the strategies and protocols we use for our elite athletes, has great applicability for regular individuals with more modest goals and aspirations. Just as racecar tech filters down, our approach shows you how to turbocharge your strength training, making you more powerful and muscular with far greater time efficiency. We get the most results from the least amount of training time.

Strength Is the King Bio-Motor Attribute

Strength is the most important bio-motor attribute. The five bio-motor attributes are speed, strength, endurance, flexibility, and agility. Strength is the premier bio-motor attribute because strength bleeds over into the other attributes. Without muscular strength there is no speed. Without muscular strength there is no sustained strength or strength endurance. Strength is the undisputed bio-motor King.

Strength has many definitions and many expressions; muscular strength is varied and nuanced. How do we define muscular strength? How do we differentiate between different types of strength? For generalized purposes, strength can be broken out into three broad categories.

The Three Muscular Strength Training Modalities

Strength modality Training emphasis Payload Velocity Stroke length Best epitomized by
Absolute strength Maximum force production Maximum payload Minimum velocity Short rep-stroke Powerlifting
Explosive strength Maximum speed with moderate load Moderate payload Maximum velocity Maximum stroke length Olympic weightlifting
Sustained strength Strength endurance and repeated effort Light payload Sustained velocity Rep strokes vary MMA-style training

There are shades and degrees between each of the three generalized muscular strength types. Many training activities will fall in a grey zone between the generalized types.

No one strength system optimizes all three generalized strength types simultaneously. To the contrary, each of the three strength types deserves its own training strategy. Optimally, three distinctly different strength training regimens are created and set into motion; three training templates exist within the overarching training template and are executed simultaneously. Each successive week, a periodized, preplanned game plan is adhered to in three distinctly different modes. Each successive week performance is inched upward.

Why the Complete Athlete Trains All Three Strength Modes

The complete athlete needs to train all three types of muscular strength. The trainee’s strong and weak points will dictate training emphasis and resultant deemphasis. All three modes need be present and trained within the weekly template; all are included in an overarching periodized game plan. All serious transformative athletes preplan. As the old adage goes, “A goal without a plan is a wish.” Each strength mode, absolute, explosive, and sustained, deserves a seat at the periodization table.

  • Absolute strength: for obtaining optimal absolute strength, power training is the ticket. You will need squat racks, a weight bench that inclines, an Olympic barbell, preferably a power rack, and dumbbells.
  • Explosive strength: for obtaining explosive strength, all that is needed is a barbell and squat rack. Rubber bumper plates are ideal. In Olympic weightlifting, the negative of the rep is avoided; bumper plates reduce noise and damage.
  • Sustained strength: sustained strength tools and modes are varied. All-out running up a steep hill, sprint rowing, MMA training and kettlebells hoisted for protracted periods are all valid. The modes for performing sustained strength are limitless. Access aerobic intensity by wearing a heart rate monitor.

Sample Weekly Strength Training Template

How would you weave all three modes into a weekly training template? Here is one hypothetical training split for an intermediate trainee that trains five days a week.

Day Primary strength work Sustained strength or conditioning
Monday Power snatch, hi-bar back squat, calf raises, leg curls  
Tuesday Plyometrics, bench press, dumbbell bench, triceps Sprints, 30 minutes
Wednesday Power clean, kettlebell ladders  
Thursday Overhead squat, deadlifts, Romanian deadlifts, curls Kettlebell swings, snatch
Friday Jerk off racks, barbell press off racks, strict laterals Sprint swim in pool
Saturday Off Jog in the park
Sunday Off Games or active rest

If an explosive lift or drill is to be done, it is always positioned first in the workout, when the central nervous system is fresh. Power training holds down the second position within the workout structure. Sustained strength drills and activities are placed last or done at different times or done on different days.

Ruthless Self-Assessment and Weak Point Training

The template should be adjusted based upon your particular strengths and weaknesses. The idea is to reapportion available training time towards addressing weak points. We all have our likes and dislikes, our preferences and tastes; we like sameness and repetition. However, sameness is the enemy of progress.

Stop continually playing to your strengths. Begin concentrating on weaknesses. The greatest gains lie hidden in plain sight. If a man is big and powerful and forty pounds overweight, it doesn’t take a genius to see the need to cut back on his beloved power training in favor of more sustained-strength cardio-biased training, and he should clean up his eating. If a man has the cardio to compete in marathons but is so weak he cannot lift 100 pounds overhead, that individual will need to reel in his umpteen miles per week and reapportion recovered training time towards hardcore weight training, and start eating nutrient-dense power foods.

Ruthless self-assessment is critical for the serious athlete seeking progress and transformation. A weekend warrior can engage in pretend fitness, doing the fun stuff over and over, staying in the comfort zone, growing ever more disproportional and imbalanced as the years roll by. Left unchecked, imbalance can lead to overuse problems, technique breakdown, and avoidable training setbacks. Untrained body parts are zones of weakness and vulnerability.

If a beginner seeks to become an intermediate, they need to bring up their weak points. At least get the deficits back to zero. Lacking cardio? Emphasize sustained strength while backing off the absolute strength. Are you fit but weak? Time for some explosive power cleans and heavy, deep barbell squatting. A specialization program designed to improve weak points will realistically require 10 to 12 weeks of concentrated effort.

Rules for Training Absolute, Explosive, and Sustained Strength

Once a general balance is achieved, once weak points are attended to, the optimal training template pays equal homage to each of the three generalized definable strength types. Here are a few rules to abide by.

  • If performing an explosive Olympic lift, always do it first in the routine and keep the reps low, 1-2 reps. Avoid the negative. The central nervous system needs to be fresh. Do the explosive lifts first, do them for low reps and avoid the eccentric portion of the rep. Seek maximum central nervous system activation needed to create genuine explosiveness.
  • On the absolute strength exercises, squats, bench presses, deadlifts and overhead presses, use a maximum range of motion and consciously accentuate the eccentric. Muscle, power, tendon and ligament strength are radically increased when perfect technique is paired with intelligent programming. Arm work, biceps and triceps, are not periodized.
  • Make haste slowly with sustained-strength drills. Warm up thoroughly before exerting maximally for extended periods. The tools can vary: a moderate-weight kettlebell hoisted over a protracted period can be highly demanding. An intense MMA training session will have the fighter roll from one all-out effort to the next, linking exercises.

Equipment Pairings for the Three Strength Training Modalities

Training all three strength modalities does not require a warehouse of equipment, but it does require the right tools for the goal. Absolute strength needs sturdy barbell infrastructure. Explosive strength needs a responsive Olympic barbell and suitable loading. Sustained strength needs tools that can be used for longer repeated efforts without turning the session into random fatigue.

For absolute strength training, powerlifting-style squats, bench presses, and deadlifts can be supported by a Body-Solid Commercial Power Rack, a Body-Solid Multi-Press Rack, weight plates, and a serious power bar such as the Iron Cowboy Powerlifting Bar. The rack, bar, and plates should allow the athlete to train heavy, repeatable lifts with technical control.

For explosive strength, Olympic weightlifting and power variations depend on bar speed and safe loading. A facility can build around Olympic weightlifting bars and IRON COMPANY premium rubber bumper plates when power snatches, power cleans, jerks, overhead squats, and fast pulls are part of the weekly training plan.

For sustained strength, kettlebells and dumbbells remain brutally useful. A home gym, school weight room, commercial facility, first responder gym, or military fitness room can compare IRON COMPANY urethane kettlebell sets, IRON COMPANY urethane hex dumbbells, and American Barbell Series 1 urethane dumbbells when programming kettlebell ladders, dumbbell bench work, assistance exercises, and strength-endurance drills.

Training Note

This article is strength training commentary, not medical advice or a universal program. Heavy squats, deadlifts, bench presses, Olympic weightlifting, kettlebell drills, sprint work, and sustained-strength training require appropriate technique, warm-ups, loading, recovery, and coaching when needed. The useful lesson is not to do everything at once recklessly; the lesson is to identify which strength modality is being trained and match the method to the goal.

Strength Training Modalities FAQ

What are the three muscular strength training modalities?

The three broad muscular strength training modalities are absolute strength, explosive strength, and sustained strength. Absolute strength is best represented by powerlifting, explosive strength by Olympic weightlifting, and sustained strength by repeated-effort strength-endurance training.

Why is strength the most important bio-motor attribute?

Marty’s view is that strength is the King bio-motor attribute because it bleeds into the others. Without muscular strength there is no speed, no meaningful strength endurance and no powerful athletic movement.

Can one strength training system optimize all three types of strength?

No single system optimizes absolute strength, explosive strength and sustained strength at the same time. Each strength type needs its own strategy, loading style, tempo, and place in the weekly training template.

What equipment is needed for absolute strength training?

Absolute strength training is built around heavy compound lifts such as the squat, bench press, and deadlift. A practical setup includes a power rack or squat rack, Olympic barbell or power bar, weight plates, a bench, and enough room to lift safely.

Why should explosive lifts come first in the workout?

Explosive lifts should come first because they require a fresh central nervous system. Power snatches, power cleans, and jerks depend on speed, coordination, and maximum velocity, so they should not be saved for the end of a fatigued workout.

How should sustained strength be trained?

Sustained strength can be trained with kettlebells, sprint rowing, hill running, MMA-style circuits, and other repeated-effort drills. The key is to warm up thoroughly, progress gradually and match the sustained-strength drill to the athlete’s current capacity and goal.
