You Won't Believe the 5 Dumbbell Mistakes That Are Sabotaging Your Gains—Fix Them Now!

In the realm of fitness, many individuals strive for optimal performance, but not all workout techniques yield the desired results. This is where social media can play a pivotal role in shaping our understanding of effective exercise. Abdul Hassoni, a personal fitness coach and Instagram creator, recently shared valuable insights that could help gym-goers enhance their workout routines.

In a video posted on December 6, 2025, Hassoni emphasized the importance of proper form during exercises, particularly when using dumbbells. He acknowledged that mistakes in the gym are common but pointed out that some errors could lead to inefficient workouts and even injury. "When you see someone doing this exercise… 🤔," he alluded, setting the stage for a deeper conversation about technique.

One of the primary pitfalls he identified involves the way many people hold dumbbells. Hassoni cautioned against bending the arms while lifting. He explained that this common mistake primarily engages the biceps instead of targeting the right muscles. "When using dumbbells, we are working against gravity. This means the force is directed up and down. If you bend your arm while holding a dumbbell, you're primarily engaging the biceps," he stated, highlighting the need for a more effective approach to targeting shoulder muscles.

The focus of Hassoni's advice was on the importance of targeting the infraspinatus and rotator cuff muscles, which are crucial for shoulder stability and overall upper body strength. He pointed out that to effectively work these muscles, the application of force should be directed sideways rather than just vertically. "The goal of this exercise is to target the infraspinatus and rotator cuff, which requires the force to be applied sideways. That's why the cable machine is the better option," he urged, advocating for the use of a cable machine for precision in targeting these often-overlooked areas of the shoulder.

However, for those who prefer using dumbbells, Hassoni offered an alternative technique. He advised leaning forward while lifting the dumbbells up and down instead of to the side, which can still engage the necessary muscles effectively. This adjustment allows users to maintain the benefits of dumbbell workouts without compromising on proper form. "Did you know this?" he asked, encouraging his audience to reconsider their approach to dumbbell exercises.

Hassoni's insights serve as a reminder that fitness is not just about showing up to the gym; it's about understanding how to maximize the effectiveness of each movement. As more individuals turn to online platforms for fitness advice, the importance of credible voices in the industry becomes increasingly significant. Personal trainers and fitness experts like Abdul Hassoni can guide enthusiasts through the maze of fitness information, ensuring that they not only engage in exercise but do so in a way that fosters real, sustainable results.

In a world where fitness trends come and go, focusing on fundamental principles, such as proper form and targeted muscle engagement, remains timeless. Whether you’re a seasoned gym-goer or just starting your fitness journey, taking the time to learn from experts can make all the difference in achieving your goals.
