9. Dumbbell one arm shoulder press

It’s also known as a variation of the traditional dumbbell press, which is targets the chest, shoulders, and triceps, and can help you build strength and muscle mass.

Muscle worked

The single arm dumbbell press primarily works the chest (pectoral) muscle, but also engages the shoulders (deltoids) and triceps.

The chest muscles, or pectorals, are responsible for moving the arm across the front of the body and are heavily engaged during the pressing motion of the exercise.

The shoulders, or deltoids, also play a key role in the exercise. The front deltoid, in particular, is responsible for lifting the arm forward and upward, and is heavily engaged during the pressing portion of the exercise.

The triceps, located at the back of the upper arm, are responsible for extending the elbow and also play a role in the pressing motion of the exercise.

Is it compound or isolation exercise?

The single hand dumbbell press is a compound exercise.

A compound exercise is an exercise that works multiple muscle groups at the same time. In the case of the single hand dumbbell press, the chest, shoulders, and triceps are all engaged during the movement.

On the other hand, isolation exercise is an exercise that targets a specific muscle group, and only that muscle group, with minimal involvement of other muscle groups. Examples of isolation exercises are bicep curl and leg extension.

Compound exercises like the single hand dumbbell press are considered more effective for building overall strength and muscle mass because they involve multiple muscle groups and replicate the way the body naturally moves.

2. Movement

1. To begin the movement, press the dumbbell upward towards the ceiling, fully extending your arm. Keep your elbow close to your body and your wrist neutral (do not let it bend back or forwards)
2. As you press the dumbbell upward, focus on squeezing the chest muscles and engaging the shoulders and triceps.
3. To complete the movement, slowly lower the dumbbell back to your shoulder. Keep your elbow close to your body and control the weight of the dumbbell as you lower it.
4. Repeat the exercise for the desired number of reps, then switch sides and repeat with your other arm.
5. Maintain proper form throughout the exercise to maximize the effectiveness of the exercise and prevent injury.

3. Tips

Here are some tips and techniques to help you perform the single arm dumbbell press safely and effectively:

• Start with a light weight: It’s important to start with a weight that is appropriate for your fitness level, and gradually increase as you become more comfortable with the exercise.
• Maintain proper form: Keep your elbow close to your body and your wrist neutral (do not let it bend back or forwards) throughout the exercise to prevent injury and maximize the effectiveness of the exercise.
• Engage your core: Bracing your core will help you maintain a stable base and keep your body in proper alignment throughout the exercise.
• Focus on squeezing the chest: As you press the dumbbell upward, focus on squeezing the chest muscles to maximize the effectiveness of the exercise.
• Control the descent: As you lower the dumbbell back to your shoulder, control the weight of the dumbbell and avoid letting it drop quickly. This will help you maintain proper form and prevent injury.
• Warm-up: It’s important to warm up before performing any exercise to prepare your muscles for the workout. A simple warm-up like some light cardio or a few minutes of stretching can help to prevent injury.
• Progress gradually: As you get stronger, gradually increase the weight of the dumbbell you are using and the number of reps you are able to perform.
• Balance the muscle development: If you are doing single arm dumbbell press for one arm, make sure to do the same exercise for the other arm to avoid muscle imbalance.

4. Common mistakes

Here are some common mistakes that people make when performing the single arm dumbbell press:

• Using too much weight: It’s important to start with a weight that is appropriate for your fitness level and gradually increase as you become more comfortable with the exercise. Using too much weight can lead to poor form and a higher risk of injury.
• Not keeping the elbow close to the body: Keeping the elbow close to the body is important for proper form and to effectively target the chest muscles.
• Not controlling the descent: Letting the dumbbell drop quickly on the descent can lead to poor form and a higher risk of injury.
• Not engaging the core: Bracing your core and keeping your body in proper alignment is important to maintain stability and prevent injury.
• Not focusing on squeezing the chest: As you press the dumbbell upward, focusing on squeezing the chest muscles is important to maximize the effectiveness of the exercise.
• Not warming up: Not warming up before performing any exercise can increase the risk of injury.
• Not balancing the muscle development: if you’re only doing single arm dumbbell press for one arm, make sure to do the same exercise for the other arm to avoid muscle imbalance.
• Not keeping the back straight: Keeping the back straight is important for maintaining proper form and preventing injury during the exercise.
