Key Decision-Making Factors and Performance Rating:

1. Adjustable Resistance - 10/10

The adjustable resistance is a critical feature when it comes to power twisters. The resistance strength of this power twister can be adjusted between 22-440lbs, with 2-20 levels. This feature is particularly important as you progress in your arm strength training. Changing the resistance strength ensures that you are continually challenging yourself and adding variety to your workout. It also means that you do not need to purchase new equipment as you increase in strength. You can easily turn the knob left or right, increasing or decreasing the resistance to meet your needs in different training stages, accompanying your entire fitness career.

2. Golden Ratio Triangle Structure - 9/10

The unique golden ratio triangle structure with the ten reinforcement rivets is essential for providing the arm trainer with a more load-bearing capacity, always keeping it in a stable state. It ensures safety and stability when using the equipment, regardless of whether you are a novice or a veteran in arm strength training. The structure is perfect for exercising your wrists, arms, shoulders, chest, and back at the same time, developing your grip, building strength, and increasing the muscle strength of your upper body.

3. Totally-Enclosed Hydraulic Cylinder - 10/10

Unlike other spring-based exercisers, this power twister adopts a totally-enclosed hydraulic cylinder, which offers you stable resistance strength that will not weaken over time. This feature ensures that the equipment is safer and more durable as it does not rely on a spring that can break or injure the user. The unique safe hydraulic adjustment system principle ensures that even if you change the resistance, the opening angle of the arms does not change, and the motion track also remains the same. Thus, you do not need to change arm movements, and you can fully open your arm even if you reduce the resistance.

4. Hydraulic Pressure Protection - 10/10

The hydraulic pressure protection feature is critical as research shows that using spring-based power twisters can be hazardous. Springback is violent and can easily hurt the user. The spring in the middle can quickly pinch the user, and the spring is prone to break after prolonged use. The patented hydraulic adjustment system principle in this power twister ensures safety and durability since there is no danger of the spring breaking or causing damage. As a result, it won't rebound and hurt the user, and the safety of the user is guaranteed.

In conclusion, the key decision-making factors in this power twister include adjustable resistance, golden ratio triangle structure, totally-enclosed hydraulic cylinder, and hydraulic pressure protection. These features are critical to the performance of the equipment and guarantee the safety, durability, and versatility needed for arm strength training. This power twister is a perfect addition to any workout routine and guarantees results regardless of your fitness level.
