Khanh Hoa Youth Martial Arts: A Season Counted in 4 A.M. Training Sessions
At 4:12 in the morning on March 9, 2026, the training floor of Phuong Sai Martial Arts Club in Nha Trang was still damp from the previous night's rain. I sat in my usual corner beside the slow-turning ceiling fan and listened to the sound of hand wraps. Nguyen Hoai Phong wrapped seventeen loops, steady as a machine, never looking down. He is nineteen years old, weighs 57 kilograms, and has slept in the innermost room of this building for three years.
When the wrapping ends, the breathing begins. Phong inhales through his nose, holds for three counts, exhales through his mouth, and repeats exactly that through four rounds of bag work. Nobody counts for him. He counts inside his own head.
I have followed Phong since June 2026, when he was sixteen and had just been eliminated in the first round of a provincial youth tournament. People tend to remember the wins. I remember the sigh after every shot taken, a sound far quieter than the sighs in the stands.
One Calendar, Four Stops
The amateur martial arts season in Khanh Hoa does not open with a bell. It opens with a calendar taped outside the coaching room, where coach Tran Duc Thang marks four stops in blue marker. March is the foundation block. April is the provincial youth tournament. June is the regional event. August is the national youth championship. October and November belong to the national championship system, where the best amateurs chase a place on the national team.
Thang is 58 this year, and he fought in the traditional martial arts style before moving fully into boxing in 2026. He told me one line in February that I wrote straight into my notebook: “Young fighters here do not lack technique, they lack someone counting the rhythm for them.”

Phuong Sai Club currently has 43 fighters, 18 of them aged between 15 and 20, six coaches, and a training floor that has been in continuous use for twelve years. Students pay 500,000 dong a month. That money does not even cover electricity for four sessions a week; families and a group of former students make up the rest.
On average, one young fighter here costs four to six million dong a month, including food and lodging, hand wraps, gloves, shoes and travel to tournaments. For most families in Nha Trang, that is a sum that requires thought. I have watched three cases leave the floor simply because there was no money that month for the bus to Da Nang.
The Line Between Two Stances
Phong stands in a stance quite different from most fighters of his generation. His lead foot turns inward by about twelve degrees, and his hips sit some three centimetres lower than the standard of a pure boxer. That is the trace of six years of traditional martial arts before he moved onto the boxing floor.
I measured this posture four times over two weeks and wrote it down: at a range of 78 centimetres, Phong holds a clear advantage because low hips let him shift his stance axis quickly. Below 60 centimetres, that advantage disappears, because the low stance costs him nearly half a second to turn out of a close-range hook.

In the 2026 season, according to my records, Phong fought nine bouts, won seven and lost two. He threw an average of 151 punches per three-round bout and landed at 33 percent. In round one, his accuracy reached 41 percent. By round three, it was down to 22 percent. That drop is not unique to Phong.
“Every season has its own heartbeat, if you are willing to listen.”
I recorded Phong's breathing rate right after the bell ended each round. After round one, he needed 48 seconds to bring his breathing below 24 breaths per minute. After round two, 76 seconds. After round three, in his June 2026 regional bout against Le Dinh Khang, he needed 139 seconds and had to sit down on the stool, both arms hanging.
Phong won that fight on points, 3-2. But the three judges gave him the first two rounds, and round three belonged to Khang. I watched the footage four times to be sure my impression was right: the punches did not get weaker, the body structure collapsed.
The Problem Sits in Round Three
The familiar explanation is always stamina. That explanation is simple and pleasant to hear, but every time I find it only half true. Among the young fighters I have tracked in Khanh Hoa and Phu Yen over the past two seasons, the breakdown is not in punch power, it is in the loss of body structure after each exchange. More precisely: these fighters throw, then forget where they are standing.
In round one, while still sharp, Phong slides back onto the correct defensive line after punching. In round three, after the third punch of a combination, he typically stands still for about 0.4 seconds before realising he must move. That gap is enough for an opponent with good footwork to land a left hook.
That is why Thang devoted all of March to a single drill: throw three, slide twenty centimetres off the line, exhale, then step back in. Each session, Phong repeats this 240 times, divided into twelve sets. No heavy bag, no opponent. Only a chalk line on the floor and the sound of breathing.
Eating, Sleeping and One Scale
Phong eats four meals a day, and the meal after morning training is the heaviest. He sleeps from 21:30 and wakes at 3:50. I logged his sleep times for eleven consecutive days in February, and only two of those days fell below seven hours.
The scale in the corner of the coaching room is checked every Monday morning. In early March, Phong weighed 57.4 kilograms. By late March, he was at 59.8. Thang wants him at 60 kilograms from June, which means the entire footwork programme must be recalculated, because nearly three extra kilograms change the inertia of every turn.
The Rules of the Amateur Floor
In the amateur system, three judges score each round on a ten-point scale, based on landed shots, accuracy and control of the bout. Repeated clinching warnings cost points. This is exactly where Ho Van Tin, the club's seventeen-year-old 63-kilogram fighter, lost two bouts last season: he throws faster than anyone on the floor but clinches more than anyone in the delegation.
Khanh Hoa currently has nine licensed referees for youth events, and as far as I know only three of them have scored at national level. That means at small tournaments the quality of judging is uneven, and a young fighter can win or lose for reasons beyond his control. I always tell the young ones this before every season.
The Quiet Stars of Khanh Hoa
Beyond Phong, Phuong Sai Club has two other names worth watching this season. Dang Thi My Linh, eighteen, in the women's 54-kilogram class, took a bronze at a regional youth event in 2026 and now adds six strength sessions a week. The second is Ho Van Tin, seventeen, in the 63-kilogram class.
Neither has a personal sponsor, and both take the bus to the floor. Their seasons, like Phong's, appear on no bulletin unless they win something notable. The quiet stars of Nha Trang never go out, their light simply does not reach the stands.

The Blind Spot in the Stands
In conversations with fans in Nha Trang, I keep hearing the same refrain: young Vietnamese fighters hit too softly, there is no knockout. That remark is not entirely wrong, but it complains about the wrong variable. The footage I rewatch shows punch power in this group rising steadily year by year. What is not rising is the ability to hold position.
Another blind spot comes from how the media treats winners. An eighteen-year-old who wins three bouts in a row is instantly named young talent of the year. Six months later, when he loses, nobody asks why. I set a rule for myself back in 2026, after I mispronounced a foreign fighter's name on air and was corrected as I deserved: I do not call anyone a talent before they have proven it across at least two seasons.
At 61, I write more slowly than my younger colleagues. Every figure in this piece has been checked against my field notebooks and against the footage, and I usually verify three times before filing.
The Signal in August
The national youth championship in August 2026 is expected to be held in Da Nang. Phong will no longer fight at 57 kilograms. He has gained nearly three kilograms in three months, and under Thang's plan he moves up to 60 kilograms from June.
What matters is a small indicator: punch accuracy in round three. If that figure passes 30 percent at the heavier weight, the twenty-centimetre slide drill has settled into the body. If it does not, the entire weight-gain plan needs revisiting.
The stands are empty, but I hear the applause of people who do not give up. At the March 9 session, when Phong finished the twelfth set of the slide drill, Thang said nothing. He simply tapped the floor frame twice. Phong nodded, bent down to rewrap his hands, and started again from the first loop.
I write slowly because I want to remember for a long time, like a man keeping time for the whole floor. A long season lies ahead. People will remember the medals; I will remember the breathing that came back even after the last round of training.
