• Left arm corresponds to right leg, right arm to left leg.
• Keep elbows bent at about 90° and let the arms hang naturally at the sides of the torso.
• Swing arms back and forth as you run.
• Adjust swing amplitude according to leg stride: larger strides mean larger arm swings; faster leg turnover means faster arm swings.
  When upper and lower limbs work together in sync, the rhythm naturally emerges.

• Sprinting → high‑frequency breathing (e.g., one breath in and one out per step, or two steps inhale, one step exhale).
• Jogging → low‑frequency breathing (e.g., three steps inhale, one step exhale if speed is slow).
  Rapid inhalation can cause air to rush into the nasal cavity, throat, and trachea, sometimes leaving the mouth and throat dry; exhalation has no such drawback, so you can fully expel waste air from the lungs within one step. Let leg cadence drive breathing rate, and let breathing rhythm guide leg rhythm.

• Power comes from the thighs — lift them high to drive the lower legs forward.
• This lets the thighs control stride rhythm, increases stride length, and lets you run faster and more easily.
  During running, the key point of force application is the thigh; once the thigh is lifted properly, speed can be maintained effortlessly.

The ankle joint is a very important joint in the human foot. It bears the greatest amount of body weight of any joint in the body — in simple terms, it supports almost our entire body. Although the ankle is capable of bearing our full body weight, it is also prone to sprains.

Ankle sprains are very common in everyday life. They often happen during intense exercise or from accidentally twisting the ankle — this is called an acute ankle sprain. Causes can include uneven ground, inadequate warm-up before exercise, or wearing unsuitable footwear for sports.

If an ankle sprain occurs, what should we do? Don’t panic — rehabilitation experts will teach you first-aid methods. Save them now!

01 Do Not Move It Randomly​

When you discover an ankle sprain, avoid moving the ankle unnecessarily. Protect the injured area as much as possible and do not overstretch the affected site, as this can cause secondary injury. Don’t take it lightly just because it seems like a minor issue — walking around casually after a sprain may worsen the condition, leading to ligament strain, which will make recovery more difficult.

02 Apply Cold Therapy​

Cold therapy is the best way to reduce swelling and also helps treat ankle sprains. Fix an ice pack to the injured area, applying cold for 10–20 minutes, then resting for 10 minutes. Repeat this cycle for up to two hours to achieve a swelling-reducing effect and relieve pain. Note: Experts advise against​ using heat. If possible, always use cold therapy — cold, cold, cold!

03 Immobilize the Injured Area​

After a sprain, be sure to immobilize the area with a bandage. Wrap the ankle with appropriate pressure to increase joint stability, promote capillary constriction, and reduce fluid leakage. This approach helps prevent long-term complications. Keeping the limb at rest is the best state for healing.

04 Elevate the Affected Limb​

When sleeping, reduce pressure on the injured area by placing a pillow or soft cushion under the ankle. This promotes blood circulation in the foot and leg.

The above are the first-aid steps for ankle sprains. Experts remind us that medication cannot replace later-stage rehabilitation. After managing the acute phase of an ankle sprain, appropriate functional exercises and rehabilitation training should be performed. If the sprain is severe, seek medical attention promptly so a doctor can determine the next treatment plan.

It’s also important to note: when running or participating in sports, it’s best to wear ankle braces and perform a proper warm-up. This is the best and lowest-cost preventive measure. Don’t wait until you sprain your ankle to regret it — that would be a loss rather than a gain.

The chest fly is one of the core foundational exercises for chest training. Its primary movement logic involves the upper arms moving forward from behind, targeting the pectoral muscles while also engaging the anterior deltoids. The bench fly serves as its fundamental form, with variations like the butterfly machine fly and the cable fly evolving from it. Mastering the fundamentals of the chest fly can significantly enhance the contraction sensation in the chest muscles and improve sculpting results.

01. Supine Flying Bird: The go-to exercise for beginners to master chest squeezes

The Flying Bird exercise derives its name from the wing-flapping motion of the arms, making it the most accessible foundational chest-pressing movement. Its step-by-step breakdown is clear, and the force application is precise.

1. Starting Position: Lie flat on your back, chest lifted, shoulder blades naturally retracted to establish a foundation for chest muscle engagement.

2. Starting Position: Grasp dumbbells with hands, arms extended naturally, elbows slightly bent—never lock them straight.

3. Core Activation: Engage your chest as the power source, palms facing each other. Pull hands toward the center, feeling the pectoral muscles contract. Slowly return to starting position, maintaining a steady pace throughout.

02 Key Points for the Lying Fly Exercise

To maximize the effectiveness of the lying dumbbell fly exercise while avoiding joint injuries, strict adherence to movement details is essential. The core focus revolves around the elbow joints and range of motion.

1. Keep elbows naturally flared outward. Avoid pinching elbows together to generate force, as this may lead to insufficient pectoral muscle activation.

2. Maintain a slight bend in both elbows throughout the movement. Perform the exercise solely through shoulder joint action, excluding elbow joint involvement to reduce joint stress.

3. Control the range of motion. When lowering the weights, avoid excessive descent. Stop when a natural stretch is felt in the chest muscles to prevent shoulder joint compression.

03Incline/Decline Bench Variations: Incline Bench / Decline Bench

Flat bench flyes focus on overall chest sculpting. Using an incline or decline bench for flyes allows for precise targeting of specific chest areas, catering to diverse sculpting needs. The incline bench flye targets the upper pectoral muscles more effectively, making it ideal for building upper chest mass. The decline bench flye, on the other hand, focuses on developing the lower pectoral muscles, helping to sculpt the lower chest line and create a fuller, more balanced chest shape. The execution technique remains consistent with the flat bench flye; only the training equipment needs to be adjusted.

04 Butterfly Machine + Gantry Frame, Enhanced Power Generation in the Pull Phase

After mastering the basic supine fly, you can try fixed-machine and gantry-style chest flys to reduce compensatory movements and further enhance pectoral muscle contraction tension. Both variations adhere to the core principle that “the closing position determines the training focus.”

1. Butterfly Machine Chest Fly: Utilizing fixed equipment allows for easier focus on the chest muscles. Seat height determines the targeted area: – A higher seat position brings hands together below the chest, emphasizing the lower chest. – A lower seat position brings hands together higher up, primarily targeting the upper chest.

2. Cable Chest Fly: Offers greater flexibility, maintaining continuous tension on the chest muscles. Bringing hands together higher targets the upper chest, while a lower position stimulates the lower chest. This is a common chest-strengthening exercise in gyms.

Regardless of the chest fly variation chosen—whether incline dumbbell flyes, cable chest flyes, or cable pulley chest flyes—one universal principle remains inviolable: Maintain a constant slight bend in the elbows throughout the entire movement. The arm opening and closing motion should be performed solely through the shoulder joints, with the elbow joints never engaging in the effort. Only by adhering to this principle can the chest muscles become the true primary movers, preventing compensation and ensuring training effectiveness. To maximize efficiency in chest fly exercises, understand the synergistic muscle logic: the pectoralis major and latissimus dorsi are opposing muscle pairs. Contraction of the pectoralis major pulls the arms forward, while contraction of the latissimus dorsi pulls them backward.

The humerus shaft is a vital component of our arm, serving both as a structural support and a power generator. A healthy humerus shaft ensures the ability to perform daily activities and labor.

In daily life, this bone may sustain accidental fractures due to lifting excessively heavy objects, impact from heavy blows, landing on this area during falls, or even in throwing athletes. So, how can we prevent this issue?

01 How to Prevent Humerus Shaft Fractures

To prevent fractures of the humeral shaft, the solution is actually quite simple: avoid subjecting this area to heavy impacts, refrain from lifting weights beyond your physical capacity, and especially avoid landing on this part of the body during falls. Additionally, for throwing athletes—such as shot putters, javelin throwers, or basketball and soccer players—it’s crucial to not only warm up thoroughly before competition but also wear specialized protective gear. This provides better safeguarding against the pain of fractures.

02 Managing Daily Life After a Fracture

1. Dietary Considerations

Following a humeral shaft fracture, special attention must be paid to dietary habits. Prioritize foods rich in protein and vitamins, as these not only replenish essential nutrients but also promote bone healing. Avoid spicy or irritating foods, as they may aggravate the wound and hinder recovery. If the patient has habits like smoking or excessive drinking, these should be avoided during this period. Not only can they irritate the affected area, but the patient may also be taking antibiotics or other medications due to the injury. Medication safety must be prioritized during this time.

2. Lifestyle Management

Patients with humerus fractures should cultivate scientifically sound habits, including maintaining a regular sleep schedule with early bedtimes and wake-up times. Adequate rest facilitates recovery. Supplementing with vitamin D or calcium, combined with moderate sun exposure, supports healing at the injury site.

3. Psychological Aspects

Suddenly losing the use of one’s arm is profoundly distressing. Beyond physical pain, patients endure significant psychological strain. Therefore, maintaining a positive mindset is crucial. Stay optimistic and cheerful—avoid negativity or self-pity, as these attitudes hinder healing.

03 Postoperative Recovery Exercises

Exercise 1: Dumbbell Row

Key Points: Assume a bent-over position, supporting yourself with your healthy arm on a bench or table. Slightly bend forward to a comfortable angle. Hold the dumbbell with your affected arm, letting it hang naturally. Exhale as you pull the dumbbell backward, then inhale as you return to the starting position. Perform slowly without rushing, repeating continuously. Duration: Approximately 24 seconds. Perform 3 sets of this exercise, with each set consisting of 8 repetitions.

Exercise 2: Single-Arm Dumbbell Bench Press

Key Points: Lie supine (on your back), preferably on a bed. Place the healthy arm flat alongside your body. With the affected arm, grasp a dumbbell using one hand. Avoid using a weight that is too heavy, as this may cause strain. Slowly lift the dumbbell upward with one hand at a moderate pace. Push upward while exhaling and lower while inhaling. Repeat this motion. Each repetition should take about 10 seconds. Perform 2 sets of this exercise, with each set consisting of 5 repetitions.

These two exercises serve both training and recovery purposes. Perform them 2 to 3 times daily, approximately 40 minutes after meals. They effectively enhance upper limb joint stability, restore arm function, and improve overall strength.
