Swim Coach in Singapore: Jina Woo
Competitive swimming coach & former SEA Games athlete
From competing for Singapore to coaching the next generation of swimmers, Jina knows what race-day pressure feels like and what it takes to get faster.

A life in the water
Jina Woo is a competitive swimming coach in Singapore and the founder of Swimduro (2017). She currently coaches 5 swimmers from Chinese Swimming Club, teaches swimming at Rainbow Centre, and her weekly stroke correction took one 200m freestyler from 3:42 to 3:07 in about five months.

Jina Woo (胡心旖) started competitive swimming at age 5, and it has been her passion ever since. She went on to represent Singapore in finswimming in 2003, and represented Singapore as a national swimmer from 13, and at the 2007 SEA Games in Thailand she represented Singapore in triathlon, the youngest female triathlete at the time.
She founded Swimduro to offer results-focused swim coaching for everyone from recreational swimmers to high-performance competitors. Her coaching is methodical and technique-first, with a positive, never-give-up mindset.
Outside the pool, Jina regularly answers stroke-technique questions from swimmers on an international swimming forum on Facebook, where her advice has been publicly commended. Helping swimmers become more efficient in the water is what she loves to do.
Her belief is simple: swimming should be done with the right technique from the start. When the stroke is right, swimmers go further and faster, and they enjoy it more.

Outside the pool
Volunteering with SG Assist
Since early in the pandemic, Jina has volunteered through SG Assist. When she is not teaching swimming, she checks the app for requests and, if her schedule allows, goes: buying daily necessities and bringing them to people’s homes, sometimes carrying 15 to 20 kg up to their doors, and on occasion escorting elderly residents to the doctor.
Her volunteering was featured in a Mediacorp television segment in 2021.
“I feel there are a lot of people in Singapore who need help. Usually I’ll do whatever I can, within my ability, to help them.”


“I have no choice; since I’m going to help people, I have to carry it.”

In the press
Featured in an SPH Chinese newspaper
A Chinese-language feature by reporter 王佳慧 (Wang Jiahui), headlined 运动健将当义工 教长者残障者游泳 (“Athlete volunteers, teaches seniors and people with disabilities to swim”), told Jina’s story: she represented Singapore in triathlon at the 2007 SEA Games, a knee injury later ended her competitive career, and in 2017 she set up a small swim school teaching children.
It described how, when COVID-19 stopped her swim lessons, she began volunteering through the SG Assist app, offering companionship, escorts to medical appointments and grocery runs for seniors and low-income families, and how she once helped a lost elderly man who could no longer walk get safely to help.
“I have taught children with autism before, and I’ve recently started learning how to teach stroke patients to swim. Once I’ve gained the professional knowledge, I can teach people with disabilities.”
“This volunteer work is very meaningful.”

Coaching moments

Coaching philosophy
“I didn’t set any goals for him. I just said keep trying, keep working on the small details, because this will eventually work. Change your cannot to can, because everything is possible if we continue to believe.”
Jina sees herself as part of a team: the swimmer brings the determination, the club coach brings the daily training, and she fine-tunes the missing gaps. See what that looks like in race results →

Questions about Coach Jina
Who is Coach Jina?
Jina Woo is the founder and head coach of Swimduro. She began competitive swimming at age 5, represented Singapore from the age of 13, including finswimming in 2003, and raced for Singapore at the 2007 SEA Games (24th SEA Games, Thailand) in triathlon — the youngest female triathlete at the time.
What qualifications does Coach Jina have?
Coach Jina is a registered NROC swimming coach on SportSync (Sport Singapore’s coach registry), with SG Coach Level 1 Coaching, National Coaching Accreditation Programme (NCAP) Theory, Values and Principles in Sports, Understanding Safe Sport as a Coach and a current Standard First Aid certificate, all publicly verifiable on SportSync. She also holds NROC registration in triathlon, SwimSafer credentials, and the AUSTSWIM Teacher of Adults qualification, and recently completed Singapore Aquatics’ SG Coach Adaptive Swimming Teacher Course (for teaching swimmers with diverse needs). She currently teaches swimming at Rainbow Centre, a Singapore special education school for children with autism and multiple disabilities. See the full list with links to the official sources on her About page.
Do you coach swimmers from clubs like Chinese Swimming Club?
Yes. Coach Jina is currently coaching 5 swimmers from Chinese Swimming Club, and works with swimmers from other Singapore clubs too. She is an independent private coach, not affiliated with any club, and her sessions complement squad training.
How fast will my child see results?
Every swimmer is different and no honest coach can guarantee a time. In our published case study, a competitive 200m freestyler went from a 3:42.66 PB to 3:07 over about 5–6 months of once-a-week stroke correction, with measurable drops at almost every meet along the way.
Does private stroke correction replace my child’s swim club?
No. Coach Jina works alongside your club coach, not against them. Club training builds fitness, rhythm and race exposure; her once-a-week session fine-tunes the technical gaps a busy club coach may not have time to spot in a big squad, so your child brings better strokes back to every club session.
How much does a private swim coach cost in Singapore?
Fees from $160 per 1-hour session. Coach Jina comes to your pool or condo, so there is no travelling across the island for your swimmer. WhatsApp her with your swimmer’s level and location for an exact quote.
Where are lessons held?
At your location. Coach Jina comes to your condo pool or a public pool near you, mainly in central Singapore around Henderson and Bukit Merah, and further afield depending on availability. WhatsApp your area to check availability.
