163cm 42kg Jang Nara, Power in a Slender Body...Thanks to what workout?

Recently, actress Jang Nara shared a video on her Instagram with the caption "Strength," showcasing herself practicing boxing. In the video, she is wearing boxing gloves and throwing powerful punches. Despite her petite and delicate frame, she demonstrates a strong, stable stance and technique, catching the attention of viewers. Her profile lists her height at 163 cm and weight at 42 kg.

Fans were impressed by her performance, with comments such as, "Her power is no joke," and "I wish she would do action roles."

Boxing is Great for Fat Burn and Muscle Strengthening

Jang Nara’s newfound passion for boxing is a high-intensity cardiovascular workout that effectively raises the heart rate and burns fat. In just one hour of training, you can burn between 500 to 800 calories, and the quick movements strengthen the heart and lungs.

While boxing is primarily an aerobic exercise, it also offers muscle-strengthening benefits. Throwing powerful punches and performing quick movements help build muscle, and using strong force during technique training targets the abdominal and core muscles, helping to tone them.

Stretching before and after boxing, as well as skipping rope, can prevent injuries and maximize the workout benefits. Boxing also stimulates muscles that are rarely used, such as the inner arms and inner thighs, helping to improve muscle tone and elasticity. Since boxing engages the entire body, it can contribute to a well-balanced physique.

Essential Warm-Up, Stretching, and Protective Gear

However, boxing is a strenuous sport that carries a high risk of injury. Poor form can strain areas like the shoulders, back, and knees, so it’s essential to perform warm-up exercises and stretching to prepare the body adequately.

Wrist injuries are among the most common in boxing, so it’s crucial to wear wraps, gloves, and protective gear. The size and weight of the gloves should be chosen based on the individual’s hand size for comfort and safety.

For individuals with existing wrist, knee, or shoulder issues, it’s important to consult with a professional to determine the appropriate exercise methods and intensity. Additionally,
