How to Do the Dumbbell Z Press for Muscle & Shoulder Strength

The Z press increases deltoid activation. 

Shoulder press exercises are particularly beneficial for those who aim to sculpt solid and robust upper body muscles. They warrant significant attention during workout sessions. According to a study by the National Library of Medicine, comparing three upper body exercises (bench presses, incline presses, and shoulder presses), shoulder presses emerged as the superior choice for developing the trapezius and anterior deltoid muscles (1). The Z press, an advanced variation of the upper body press, elevates shoulder muscle and enhances strength to remarkable levels. While it poses a considerable challenge, the rewards include extensive gains across multiple muscle groups for athletes willing to persevere.

This article delves into the Z press, spotlighting its advantages and the specific muscles it targets. It provides a detailed, step-by-step guide on executing this exercise with the correct form. To help athletes maximize the benefits of their shoulder training, the article also recommends several alternative exercises to diversify and enrich their workout routines.

Techniques & Muscles Worked

The Z press is a functional exercise that works your traps, triceps, pecs, and deltoids (lateral and anterior). It isn’t just limited to strengthening these muscles; Z-presses also work the shoulder joints, strengthening and stabilizing them. This routine equally places constant tension on core muscles like the abs and obliques, using them for stabilization.

Powerlifters and strongmen popularly used this exercise, a more intense variation of the shoulder presses, to strengthen their upper bodies. You can do this with a machine or using free weights like dumbbells, kettlebells, or barbells. However, in this guide, we shall be discussing how to perform the Z press using dumbbells.

The Z press requires a full range of motion and an insane amount of strength and technique. Remember to keep your body sturdy and brace your core to reduce the risk of injuries. Here is a step-by-step guide to performing this exercise.

1. Sit on the ground with your legs straight while grasping the dumbbells with a neutral grip. 
2. Bring your elbows forward, keep your back straight, and brace your core muscles. This is your starting position. 
3. Next, slowly push the dumbbell overhead until you fully extend your arms.
4. Pause for about one to two seconds and slowly reverse the movement back to the starting position to complete a rep. 
5. Perform for as many reps as you desire.

Benefits

The Z press is a compound movement that works more intensely on multiple muscles than regular shoulder presses. This causes lots of muscle hypertrophy in a short time. Below are more benefits of this exercise.

Builds & Strengthens the Shoulders

The dumbbell Z press is an exercise that primarily targets your shoulders. It focuses particularly on the lateral and anterior deltoids. This helps improve mobility and reinforces your upper muscles, giving them that aesthetically pleasing look. 

Activates Core Muscles

This exercise requires a lot of stability, so it recruits the core muscles. They help maintain the right form and equal load distribution throughout the body. Your core also helps keep the shoulders and torso stable and prevent injuries, especially when exercising.

Treats Muscle Strength Imbalances

The Z press allows you to strengthen your shoulders and body unilaterally. This means you can train each part differently, addressing any strength and muscle imbalances and enabling you to point out your weaker side. You can also use this unilateral training to work through injuries.

Improves Your Range of Motion

When performing this exercise, you use a full range of motion, working the shoulder joints, rotator cuffs, and scapular stabilization. This helps improve your upper body movements and allows you to lift heavy objects through different ranges of motion.  

Better Mind-Muscle Connection

Focusing on the target muscles requires a lot of concentration. This helps you build a better mind-muscle connection, and studies show that focusing on specific muscles and building a mind-muscle connection can increase muscle activity (2).

Transitioning to Other Exercises

The Z press is a prime upper body and core-building exercise. Working these target muscles can improve your form for CrossFit and Olympic lifts. It also enhances regular exercises like pull-ups, bench presses, and deadlifts. 

Dumbbell Z Press Alternatives

Dumbbell Z presses are excellent exercises for bodybuilders to develop strong shoulders. However, experts have advised integrating other exercises that build similar muscles to improve your training regimen and avoid a plateau. Here is a list of alternative exercises you can try.

Mike Tyson Pushup

Mike Tyson pushups are bodyweight exercises that primarily work the upper body muscles. It combines the downward dog pose and traditional pushups, giving you the best two-in-one exercise. If you’re looking for more resistance, add resistance bands.  

Landmine Press

Landmine presses work similar muscles to the Z press. They can also be done unilaterally, allowing for separate training on one side of the body. This exercise places less stress on your shoulders.

Kettlebell Front Rack Hold

The kettlebell front rack holds are excellent isometric exercises that work the upper body muscles. They also help strengthen your grip and activate core muscles. You can use this exercise to perform a variety of movements and improve your mobility.

FAQs

What does the dumbbell Z press work?

Dumbbell Z press are stable exercises for working your shoulders (front and side), traps, triceps, pecs, and core muscles. This exercise also works the shoulder joints and helps improve the range of motion, which helps hit muscles differently.

How do you do the db Z press?

You need a dumbbell to do a dumbbell Z press (db Z press). The guide above provides a step-by-step breakdown of the movement. 

Is the Z press better than the shoulder press?

Well, depending on your training preference, they both work similar muscles. However, the Z press takes the edge because it includes other muscles like the traps and a full range of motion, which helps with muscle growth.
