1. Benefits and Contraindications
Benefits:
- Maximum Calorie Burn: Burns up to 600–700 kcal per hour during an intense workout.
- Symmetrical Body Development: Evenly targets the muscles of the back, shoulders, core, and legs.
- Cardio Boost: Powerfully increases lung capacity and strengthens the heart muscle.
Contraindications (Risks of Improper Technique):
- If you have acute shoulder injuries or cervical spine herniations, consult a doctor before starting.
- Important: Swimming with your head constantly lifted (without putting your face in the water) strains the neck and can lead to vascular compression.
2. Core Focus: Step-by-Step Execution Technique
Proper freestyle is a continuous, cyclic movement. Let's break it down into 4 key components:
Body Position and Balance
- You should lie as horizontally as possible in the water. An imaginary axis runs from the top of your head to your heels.
- Face straight down, with your eyes focused on the bottom of the pool (about 1–1.5 meters ahead). Do not lift your head.
- As you stroke, your body should slightly rotate around its axis to the left and right. This lengthens your reach and engages your back muscles.
Arm Technique (The Stroke)
The stroke of each arm is divided into phases:
- Catch and Extension: The hand enters the water palm-down (fingertips first) at shoulder width.
- Pull and Push: Bend your elbow underwater and powerfully push the water back along your body, passing your hip. Keep your elbow higher than your hand ("high elbow technique").
- Recovery: The relaxed arm exits the water elbow-first and swings over the surface for the next entry.
Leg Technique (The Kick)
- Your leg movements should resemble a whip-like motion. The movement must originate from the hips, not the knees. Keep your toes pointed.
- Knees should be slightly bent and relaxed. Feet work close to the water surface, creating a soft churn (avoid excessive splashing).
- The main purpose of the flutter kick in freestyle is not just propulsion, but keeping your lower body high in the water to reduce drag.
Breathing Technique
- The Golden Rule: Inhale through your mouth to the side, exhale through your nose and mouth into the water.
- As one arm (e.g., the right arm) finishes its push at the hip and begins to exit the water, rotate your torso to the right. Turn your head just enough so one eye stays submerged, and take a quick, sharp breath through your mouth.
- Return your face to the water and begin a smooth, continuous exhalation until the next rotation.
3. Getting Started: First Steps in the Pool
If you are a beginner, do not try to swim full-coordination freestyle right away. Break it down into drills:
- Bayside Breathing: Hold onto the pool edge, submerge your face, and exhale. Turn your head to the side to inhale. Repeat 20 times to get used to the rhythm.
- The Streamline Glide: Push off the wall with your feet, extend your arms straight ahead, and glide face-down through the water until you stop.
- Kickboard Drills: Hold a kickboard out in front of you. Swim down the lane using only your legs (kicking from the hip). Breathe by lifting or turning your head.
4. Key Factors and Common Mistakes
- The "Sunken Hips" Mistake: If you lift your head to look forward, your hips and legs automatically drop. Your body creates massive drag, and your speed plummets. Fix: Look at the bottom of the pool.
- The "Bicycle Kick" Mistake: Bending your knees too much increases resistance. Fix: Relax your knees and drive the movement with your thighs and glutes.
