For beginners, it really takes time to practice and strengthen the control of strength. Generally speaking, you can increase the strength of your arms, abdomen and thighs through some physical training. Practice sit-ups, push-ups and weight-bearing squats for 10 to 15 minutes every day, and the number of times can be between 15 and 25 times. I believe you will feel different in a month. And we don't have to worry about arms and legs getting thicker and so on. We need to practice "explosive point", instead of practicing ourselves as "tough guy" or "tough girl". On the other hand, we should know where each action needs to contribute. What everyone has to do is to apply what they have learned. Don't worry, there is always a process.
In fact, no matter what your style is, don't confine yourself to your own study space. The more contact styles, the better for yourself. You can clearly find your own style among many styles, and integrate other styles to make your dance elements more diversified and your dance knowledge more abundant. This is a harmless good thing. So everyone can learn jazz dance with confidence.
Between tension and strength, personally, tension is more important. The greater the tension, the more the strength will be affected; On the contrary, the greater the strength, the weaker the tension will be. So I admire foreign dancers, so I have been trying to change myself. Also, for China dancers, it is difficult to balance tension and strength at the same time. After all, their physical qualities are different from those of foreigners. Just keep practicing, practicing. Strengthening muscle mass and improving limb control can also achieve the possibility of tension and strength at the same time.
Listen to more music, listen to all kinds of music. For example, hip-hop music and R & Pop, Reggae, House, etc. Rhythm is firstly the brain's understanding of music, then the body's feeling of music, and finally the rhythm (the body moves with music). But in short, practice more (there is no shortcut). Different styles should study contact. Let the body contact with different dance movements, thus improving the flexibility and coordination of the body. Finally, the emotional rhythm, the final performance of dance is emotional expression. No matter what style, the body is driven by emotions, and emotions are promoted by the body! Therefore, while listening and jumping, I am also practicing my emotions or consciously practicing my emotions and training my emotional control and rhythm.
