1. What is the difference between barbells and dumbbells
Both barbells and dumbbells are fitness equipment for exercising muscles, and they are often compared, but in fact, barbells and dumbbells still have The difference is that they differ in many ways:
1. Different weights
Dumbbells are smaller than barbells. The weights of light dumbbells are 6, 8, 12, 16 pounds (1 pound = 0.4536 kg) and so on. Heavy dumbbells are available in weights of 10, 15, 30 kg, etc.
There are many weight choices for barbells, such as 25kg, 20kg, 15kg, 10kg, 5kg, 2.5kg, 2kg, 1.5kg, 1kg and 0.5kg, and they can be stacked Plates to add weight.
2. Different structures
The fixed weight dumbbells are made of cast iron, with an iron rod in the middle and solid balls at both ends.
The standard barbell consists of three parts: bar (horizontal bar), barbell plate and clamp.
3. Different uses
The main function of dumbbells is for muscle compound exercise training and muscle strength training. Modifies muscle lines and increases muscle endurance.
The main function of the barbell is to do muscle endurance training for the whole body muscles. During the process of use, it can exercise many muscles such as shoulders, back, arms and chest.
Both barbells and dumbbells are better for strength training
Both barbells and dumbbells can be used for strength training, so which one is better?
1. When using a barbell, the strong body on one side can make up for the lack of the other side. Over time, there is a chance of muscle strength or muscle imbalance, but dumbbells don’t have this problem. Using dumbbells can improve the imbalance of power in our body, such as the gap between the left hand and the right hand and the left and right foot, which is more common for beginners.
2. Because the barbell is relatively stable, the training weight may be slightly higher, while the weight of ordinary dumbbells in the gym is only 50kg. The weight a barbell can carry can’t compare to dumbbells. Because barbell training can use heavier weights, barbell training is more conducive to improving muscle strength.
3. Although barbells are more stable than dumbbells, they also become their limitation, but dumbbells are more flexible! Taking the horizontal push as an example, it is difficult to achieve a full contraction of the pectoralis major with a horizontal barbell push. Conversely, a horizontal push with dumbbells will bring the upper arms almost completely at a 90-degree angle to the chest and fully contract the muscular chest.
4. Dumbbells have a greater range of motion, so muscles can contract more completely, so dumbbells activate muscles more than barbells.
In summary, the two types of fitness equipment have their own advantages for strength training. How to choose mainly depends on your own exercise purpose; in fact, whether we want to improve sports performance or increase muscle size, we all need Improve body stability, muscle strength and left-right balance. Dumbbells and barbells are both essential and indispensable.
