Best Deltoid Workout Routine
These five moves are the best deltoid exercises for effectively building strength and size in the shoulders. To enhance muscular strength and hypertrophy, perform these exercises two to three times weekly.
Lift at an intensity of 60%–80% of your one repetition maximum, or 1RM, for each. 1RM refers to the amount of weight you can lift a single time with good form.
| Exercise | Sets | Reps | Rest (Between sets) |
|---|---|---|---|
| Cable Standing Y Raises | 3–6 | 8–12 | 1–2 minutes |
| Cable Lateral Raises | 3–6 | 8–12 | 1–2 minutes |
| Dumbbell Bent-Over Face Pulls | 3–6 | 8–12 | 1–2 minutes |
| Dumbbell Reverse Flies | 3–6 | 8–12 | 1–2 minutes |
| Dumbbell Arnold Press | 3–6 | 8–12 | 1–2 minutes |
Anatomy Of The Deltoid
Anterior Deltoid
The anterior deltoid is the front portion of the shoulder muscle. It originates from the collarbone and inserts on the upper arm bone. This muscle section moves the arm in front of the body and turns the upper arm bone inward.
Exercises like the front raise, Arnold press, and push-up all work the anterior deltoid. The muscle activation rate for the anterior deltoid in a traditional push-up is 78.54%. This tells us how hard the muscle is working during the exercise.
Lateral Deltoid
The lateral deltoid is the middle portion of the shoulder muscle. It connects to the outer edge of the collar bone and inserts on the upper arm bone. This muscle moves the arm sideways, away from the body.
The lateral deltoid is highly active in moves like the shoulder press, overhead press, and lateral raise. The muscle activation rate for the lateral deltoid ranges between 40%–60% in a lateral raise which is significant engagement.
For more lateral deltoid exercise, try these cable shoulder workouts.
Posterior Deltoid
The posterior deltoid is the back section of the shoulder muscle. It runs from the shoulder blade to the upper arm bone.
The portion of the muscle moves the arm behind the body and outwardly rotates the upper arm. It also helps bring the arms toward the sides of the body from an overhead position.
Deltoid exercises like reverse flies, band pull-aparts, and face pulls target the posterior deltoids. In horizontal resistance band pull-aparts with the palms facing down, the posterior deltoid muscle activation rate is 48.3%.
Benefits Of Deltoid Workouts
Deltoid exercises can create strength, size, and stability in the shoulders. Additionally, performing shoulder strengthening exercises can reduce shoulder pain and the risk of injury.
Protects The Shoulder Joint
The shoulder is the most mobile joint in the body, which also makes it the most vulnerable. Research shows an annual rate of up to 62 cases of shoulder pain per 1,000 people.
Shoulder injuries are also prevalent in sports, especially in those with overhead actions. Studies found that 23%–38% of swimmers develop shoulder injuries within one year. Additionally, shoulder pain was found in 23% of volleyball players and 44%–75% of handball players.
Shoulder exercises improve shoulder strength and joint function. Performing shoulder mobility exercises increase flexibility which will facilitate building strength. This is because it will make it easier to control force production through the full range of motion. Performing shoulder exercises has also been found to decrease shoulder pain.
Furthermore, the deltoids directly impact the rotator cuff muscles that are responsible for shoulder stability. Muscle loss in the deltoids causes increased stress on rotator cuff muscle tissue. Chronic stress on the rotator cuff can lead to degenerative rotator cuff injuries.
Building shoulder strength with deltoid workouts can reduce rotator cuff stress. That being said, healthy rotator cuff muscles promote shoulder joint stability and decrease the risk of injury.
Sculpts The Shoulders
The deltoid muscles are what give the shoulders a sculpted aesthetic. Building hypertrophy in the deltoids will give the arms more definition.
Both dumbbell and cable lateral raises are effective at increasing lateral deltoid hypertrophy. The Arnold dumbbell press shows high anterior deltoid muscle activation. This makes it a good choice for sculpting the front of the shoulder.
Performing between 12–20 weekly sets per muscle group can build muscle mass. Using a combination of exercises that work all three sections of the deltoid muscle will produce a well-rounded definition of the shoulders.
If you are looking to gain shoulder hypertrophy, try the best shoulder workout for mass.
Improves Shoulder Strength
Functional strength in the shoulders aids in everyday tasks like reaching for items on a high shelf. The deltoids produce 70% of the shoulder’s strength when reaching overhead and 75% when extending the arms sideways overhead. Therefore, strengthening the deltoids makes overhead tasks easier and safer.
Cable dumbbell workouts and deltoid workouts with dumbbells or resistance bands can increase shoulder strength. For example, the bench press can build strength in the anterior deltoid. The strength developed from executing this push exercise can transfer to other everyday activities with a pushing motion.
How To Maximize The Benefits Of Deltoid Exercises
- Actively concentrate on engaging the target muscle group during the exercise. Mind-muscle connection can increase muscle activation, allowing you to get more out of the exercise.
- Perform the exercises with control. Avoid swinging your arms, as this uses momentum and decreases muscle work. Aim for a slow to moderate speed. Perform the up phase in 1–2 seconds and the down phase in 2–4 seconds.
- Adequate rest between sets and workouts is crucial for optimal performance. A 1–2 minute rest between sets is advised for hypertrophy goals. Between intense workouts, the targeted muscles should have 48–72 hours of recovery time.
- Hand position when executing shoulder exercises can alter which muscle head is targeted. A palm-down hand position during the up phase of a frontal raise increases anterior deltoid activation. A standard hand grip best works the posterior deltoids in a rear delt raise.
- Advanced training techniques can help progress your shoulder program. Shoulder supersets involve performing two exercises consecutively. Drop sets can aid in hypertrophy. They consist of performing an exercise until muscle failure and then, completing another set with a 25% load reduction.
- Performing shoulder exercises with specific joint angles can increase deltoid hypertrophy. Research shows that the lateral deltoid is most active in exercises performed with the following combination of joint angles:
- The shoulder joint — 90 degrees.
- The elbow joint — 180 degrees.
Conclusion
Utilize a mix of these shoulder exercises to create the best deltoid workouts. Combine exercises that work all three muscle heads to increase shoulder strength and muscle mass. By strengthening the deltoids, you are also supporting the rotator cuff muscles, contributing to joint stability.
Building strong shoulders can aid in daily tasks, especially overhead actions. This functional strength can also decrease the risk of shoulder injuries.
Frequently Asked Questions
Building hypertrophy in any muscle group, including the deltoids, requires high-volume training. To bulk up, performing 12–20 weekly sets per muscle group is recommended. Because the deltoid has three heads, choose 1–2 exercises per muscle head.
The standing cable Y hits all three deltoid heads in a single exercise. Many deltoid exercises activate two heads. For example, performing a dumbbell Arnold press hits the anterior and medial deltoid. Follow that up with face pulls to get the posterior and medial deltoid.
Deltoid strengthening consists of resistance training to make the shoulder muscle stronger. The deltoid is the muscle making up the bulk of the shoulder. It has three sides: anterior (front), lateral (middle), and posterior (back). It is important to create balanced strength on all three sides.
Like any soft tissue injury, the healing time is dependent on the extent of the injury. If you have an injury or experience pain in the deltoids or shoulder joint, seek medical advice. Discomfort from post-workout is called delayed onset muscle soreness. This typically peaks between 24–72 hours and subsides within 7 days.
