Dumbbells can be said to be a fitness artifact, favored by many fitness enthusiasts! They can train almost all muscle groups in the body, and the results are very good; so how do we choose the right weight of dumbbells for our training during the fitness process? It seems like a simple question, but it is one of the key factors that affect our training results. Choosing the correct training weight will allow us to increase muscle endurance more efficiently, making training more effective; when doing dumbbell training, heavier weights are not always better. Everyone needs to determine the appropriate weight based on their own condition! Today, the editor of New Life will talk to you about the basic principles and methods for beginners to choose dumbbell weights during fitness!

I. Basic Principles for Beginners in Choosing Dumbbell Weights

1. Safety Principle

Safety training is the top priority at all times. Don't care about the gazes of those around you, and don't envy others. Heavy weight training requires caution; do not show off or refer to the weights used by experts.

2. Gradual Progression Principle

Training cannot always use the same weight. From beginners to advanced, as strength gradually increases, training weights should also be increased progressively.

3. High Intensity Principle

In muscle-building training, the higher the training intensity, the greater the stimulation to the muscles, and the better the fitness results.

4. Sustainability Principle

The weight chosen for each training session should be appropriate. Although heavier weights can increase training intensity to some extent, excessive weight increases the risk of injury. Additionally, excessively high training intensity in a single session can affect the body's recovery and impact the overall training intensity.

II. Methods for Choosing Dumbbell Weights

1. Weight Selection for Beginners

For beginners, the most important thing is not the weight, but whether the movements in each training session are standard. Therefore, the initial weight requirement is lower, and finding the feeling of muscle engagement is more important. Additionally, lighter weights in the early stages are also very helpful for strength increase. Thus, at this time, the weight can be chosen at 50% of the maximum weight or lower, and for movements that are not yet mastered, bodyweight exercises can be used to find the feeling of engagement.

2. Choose Weight Based on Training Goals

If your fitness goals differ, the weight you choose will also vary. Below are the differences in weights.

1) 1-5RM load training can increase muscle thickness and develop strength and speed;

2) 6-10RM load training can increase muscle size, improve strength and speed, but endurance growth is not significant;

3) 10-15RM load training does not significantly increase muscle fiber thickness, but strength, speed, and endurance all improve;

4) 30RM load training increases the number of capillaries in the muscles, improves endurance, but strength and speed improvements are not significant.

Therefore, for muscle building, choose a weight that allows for 6-12 repetitions to failure; for strength improvement, choose a weight that allows for 1-5 repetitions to failure; for muscle endurance, choose a weight that allows for 15 or more repetitions.

Low weight, high repetition training can increase muscle endurance (18-25 reps/set, 3 sets). Generally, this method is more suitable for women who wish to shape their bodies, as it not only increases muscle quality but does not significantly increase muscle volume; therefore, for women aiming for body shaping and fat loss, a weight around 20RM is generally more suitable.

3. Choose Based on Your Training Area

During fitness, it is necessary to target the muscles of various parts of the body. For example, when training the chest muscles, a relatively larger weight is needed because the chest muscles are large muscles that can bear greater weights. However, when training the arms or shoulders, the required weight will be smaller than that for the chest muscles. Therefore, different muscles require different weights.

Choosing Dumbbell Weights Based on Body Weight

If you cannot measure your RM, generally, you can choose based on your height and weight. This is based on the conventional physique and exercise intensity of the population, while also considering the future stages of increasing dumbbell training intensity.

For those under 1.60 meters tall and weighing under 60 kg - 25 kg combination (one pair of 25 kg, same below)

For those under 1.70 meters tall and weighing under 70 kg - 30 kg combination

For those under 1.80 meters tall and weighing under 80 kg - 35 kg combination

For those under 1.90 meters tall and weighing under 95 kg - 45 kg combination

Choose dumbbell weights based on height and weight, measure your RM, and then choose weights again based on your training goals.

In summary: The choice of weight should primarily be based on your training goals. Relying on dumbbells to train muscles is not a one-day or two-day matter, but a lifelong endeavor. Choosing the right weight of dumbbells is particularly important, as it not only plays a good role in fitness results but also ensures a certain level of safety.
