How to Swim Backstroke Faster: A Coach’s Speed Guide
To swim backstroke faster, rotate your body from the hips so each shoulder rolls clear of the water, recover with a straight arm entering pinky-first above the shoulder, and keep your head dead still. Speed in backstroke comes from long, rotated strokes and a steady tempo, not from thrashing your arms. Learn to trust the backstroke flags so you can attack the wall instead of slowing down in fear of hitting it.
Plenty of swimmers can float on their back and paddle along. Getting genuinely quick is a different game. After years on the pool deck here in Singapore, I can tell you the same handful of fixes unlock most people’s speed. Let’s work through them.
Rotation Is Where the Speed Lives
Flat swimmers are slow swimmers. If your back stays glued flat to the surface, your arms have to muscle every stroke on their own. Instead, rotate along the long axis of your body. As one arm reaches back to catch, that shoulder rolls down into the water and the other rolls up and out.
This roll does two things. It lengthens each stroke so you cover more distance per pull, and it lets the big muscles of your back and core drive the catch instead of just your shoulder. Aim for roughly 30 degrees of roll to each side. Hips lead, head stays put.
Straight-Arm vs Bent-Arm Recovery
The arm that lifts out of the water and swings over is the recovery. Backstroke rewards a straight-arm recovery for most swimmers: the arm exits thumb-first, swings up straight and relaxed, and drops in pinky-first directly above the shoulder line. It is simpler to time and keeps your rhythm even.
| Recovery Style | How It Looks | Best For |
|---|---|---|
| Straight-arm | Arm stays straight, swings over like a windmill | Most swimmers; even tempo and easy timing |
| Bent-arm | Elbow bends over the water, hand leads | Advanced swimmers with strong shoulder mobility |
Whichever you use, the hand must enter pinky-first, little finger slicing in cleanly. A flat, slapping entry wastes energy and throws off your rotation.
Keep Your Head Still
Here is the fix that surprises people most. Your head is the rudder. If it wobbles side to side or lifts to look around, your hips snake and you lose speed instantly. Pick a fixed point on the ceiling or sky and hold your gaze there. Water should break around your ears, eyes looking straight up and slightly back. A still head keeps your body straight, and a straight body is a fast body.
Kick Steady from the Hips
Your flutter kick is the metronome that keeps everything ticking. Kick from the hips with loose ankles and pointed toes, keeping the kicks small, fast and continuous. A relaxed, steady six-beat kick under your rotation adds real drive. Stiff ankles and knee-bending kicks just create drag.
Use the Flags and Attack the Wall
The single biggest thing that slows recreational backstrokers is fear of crashing into the wall. So they slow down, sit up, and look back, killing all their speed. The backstroke flags exist precisely to solve this.
- Learn your stroke count. From the flags to the wall, count how many strokes it takes you. It stays remarkably consistent.
- Trust the count. Once you pass under the flags, count your set number of strokes and commit to a full-speed finish or turn.
- Never sit up to look. Looking back drops your hips and slows you every single time.
Once you trust the flags, you stop braking near the wall and hold your speed all the way in.
Common Mistakes That Slow You Down
- Swimming flat – no rotation means short, weak strokes.
- A moving head – wobble in the head means wobble in the hips.
- Slapping the hand in flat – enter pinky-first for a clean catch.
- Bending the knees to kick – drive the flutter from the hips.
- Sitting up near the wall – use the flags and stroke count instead.
- Holding your breath – breathe in a steady rhythm, one arm in, one arm out.
Staying Safe
Backstroke means you cannot see where you are going, so always swim in a lane with clear lane ropes, or count your strokes carefully in an open pool to avoid a head knock. Warm up your shoulders before hard efforts, since the straight-arm recovery loads them. A proper warm-up before swimming keeps the shoulders happy. Public pools managed by ActiveSG have marked lanes and lifeguards, which makes them ideal for speed work.
Frequently Asked Questions
Why is my backstroke so slow even though I’m fit?
Almost always a lack of rotation. Fitness helps, but a flat body forces short strokes. Roll your shoulders and your speed jumps without extra effort.
Should I use a straight-arm or bent-arm recovery?
Start with straight-arm. It is easier to time and keeps your tempo even. Bent-arm suits advanced swimmers with strong shoulder mobility.
How do I stop drifting into the lane rope?
Keep your head still and eyes fixed straight up. Most drifting comes from a wandering head that steers your hips off line.
What are the backstroke flags for?
They warn you the wall is coming. Count your strokes from the flags to the wall so you can finish or turn at full speed without looking back.
How do I breathe properly on backstroke?
Set a rhythm: breathe in as one arm recovers, out as the other does. A regular pattern prevents the breath-holding that tires you out.
Will private lessons help me swim faster?
Private lessons can help because a coach can observe timing faults that are difficult to feel yourself. Progress and the number of sessions vary by swimmer; enquire about private swimming lessons if you would like individual feedback.
