Kris Gethin's Ultimate Guide to Shoulder Training

Almost everyone wants bigger shoulders, but very few people actually train them effectively.

The reason is simple. Most people approach shoulder training the same way they approach every other muscle group. They load up the weight, chase numbers, and assume heavier always means better. Kris Gethin has spent decades proving that shoulder development doesn’t work that way.

According to Kris, shoulders are one of the few muscle groups that often respond better to intelligent volume, longer tension, strategic repetition ranges, and multiple training angles than they do to simply moving the heaviest weight possible.

That doesn’t mean heavy pressing has no place in a shoulder workout. Kris still believes in using compound pressing movements to recruit high-threshold motor units and stimulate overall shoulder growth. However, relying exclusively on heavy presses often leaves a tremendous amount of potential development untapped.

For Kris, shoulder training is about understanding how the deltoids function in real life and then building a training strategy around that reality.

Why Shoulders Need More Volume Than Most People Think

One of the biggest mistakes Kris sees is people underestimating how much work the shoulders can handle.

Unlike many other muscle groups, the deltoids are active throughout the entire day. Whether you’re reaching for something on a shelf, carrying groceries, lifting a bag, grabbing your shaker bottle, or simply using your arms during daily movement, your shoulders are constantly working.

Because they are exposed to frequent low-level activity, the deltoids become highly resistant to fatigue. In practical terms, this means they often require a greater training stimulus before meaningful growth occurs.

This is why Kris has consistently favored high-volume shoulder sessions throughout his career.

Instead of performing a few heavy sets and calling it a day, he often recommends accumulating significant training volume through multiple exercises, shorter rest periods, and extended workloads that force the shoulders to stay engaged for longer periods of time.

Over the years, he has seen this approach work across a wide range of body types, training backgrounds, and experience levels.

The Importance of Time Under Tension

If there is one concept Kris repeatedly emphasizes in shoulder training, it is tension.

Every muscle must spend sufficient time under tension if growth is the goal. While this principle applies to every body part, it becomes especially important when training shoulders because other muscles frequently try to take over the movement.

The upper traps are often the biggest culprit.

Many lifters perform lateral raises or other isolation movements using excessive weight. As soon as the weight becomes too heavy, the traps begin assisting the movement, reducing the amount of tension placed directly on the deltoids.

The result is predictable. The traps get more work while the shoulders receive less stimulation than intended.

Kris often encourages lifters to temporarily forget their ego, reduce the weight, slow down the repetition tempo, and focus entirely on keeping tension where it belongs. Relaxing the traps, controlling the movement, and concentrating on the contraction frequently produces better shoulder growth than adding more plates to the dumbbell rack.

In fact, Kris has witnessed countless athletes experience noticeable shoulder development after simply reducing the load and improving the quality of each repetition.

Why Higher Repetition Ranges Work So Well

Traditional gym culture often promotes moderate repetition ranges as the universal answer for muscle growth. Kris takes a more flexible approach.

Because shoulders perform significant amounts of low-intensity work throughout daily life, he believes many people possess a high percentage of slow-twitch muscle fibers in this area. As a result, moderate-to-high repetition ranges can be extremely effective.

Some shoulder workouts may include sets of 15 to 20 repetitions. On other occasions, Kris has pushed repetition ranges dramatically higher.

The objective isn’t simply to create fatigue. It’s to generate substantial blood flow, maximize cellular swelling, and keep the muscle under prolonged stress.

These higher repetition sets often create an intense pump, but more importantly, they expose the deltoids to a completely different growth stimulus than traditional low-rep strength training.

When applied correctly, this combination of volume, blood volumization, and extended tension can produce outstanding improvements in shoulder size and density.

The Power of Training From Multiple Angles

Another principle that separates Kris Gethin’s shoulder philosophy from conventional routines is his emphasis on angles.

The shoulder complex is unique. Rather than functioning as a single muscle, it consists of multiple heads that contribute to overall shape, width, and appearance. Because of this, attacking the shoulders from only one direction rarely delivers complete development.

Kris frequently uses cables to solve this problem.

One of the advantages of cable training is the ability to quickly manipulate resistance angles. By adjusting cable height, changing attachments, and altering body position, a single exercise can become several different exercises targeting the muscle from multiple directions.

This approach also makes supersets, tri-sets, and giant sets incredibly efficient.

For example, Kris may perform a cable front raise from one position, immediately change body placement, repeat the movement from another angle, and then finish with a third variation from a completely different position. Although the exercise appears similar on the surface, each angle creates a slightly different stimulus for the anterior deltoid.

Over time, these small differences accumulate into more complete shoulder development.

Kris Gethin’s Shoulder Training Philosophy in One Sentence

If there is one lesson to take away from Kris Gethin’s approach, it is this : Shoulders grow best when you stop treating them like a strength exercise and start treating them like a muscle-building exercise.

Heavy pressing still has value. However, the greatest shoulder development often comes from high training volume, strict execution, longer time under tension, higher repetition ranges, and intelligent exercise variety.

This philosophy has been a cornerstone of Kris Gethin’s training methodology for years and remains one of the reasons his shoulder workouts continue to produce exceptional results for athletes, bodybuilders, and transformation clients around the world.

The next time you train shoulders, focus less on how much weight you’re lifting and more on how effectively you’re making the deltoids work.

That’s where the real growth happens.
