How to Swim Faster: Streamline, Stroke & Turn Tips

To swim faster you cut drag first, then add power. Hold a tight streamline off every wall, make each stroke travel farther through a clean catch and full finish, tighten your turns, and only then push your tempo. Speed is efficiency multiplied by effort, so a longer, quieter stroke almost always beats thrashing harder.

Most swimmers try to get faster by working harder against the water. The water always wins. The swimmers who drop time chase the opposite goal: give the water less to grab. This guide walks through the four levers that actually move the clock, in the order that pays off fastest. If you are still building the basics, start with the complete swim technique guide and come back once your stroke feels stable.

Cut Drag Before You Add Effort

Water is roughly 800 times denser than air, so drag is your biggest enemy. At the speeds you swim, drag rises sharply as you go faster, which means a small posture fix returns a large payoff. Chase a clean body line before you chase fitness.

Focus on three things:

• Head position. Look mostly down, not forward. A lifted head sinks your hips and turns your body into a plow.
• Hips high. Press your chest slightly and engage your core so your legs ride near the surface instead of dragging behind you.
• Long body. Reach forward on every stroke so you are as long and narrow as possible in the water.

If your legs sink the moment you stop kicking hard, your line is the problem, not your engine. Fixing it makes every other change below work better. Beginners rebuilding posture from scratch will get more from swimming for beginners first.

Build Distance Per Stroke

Distance per stroke (DPS) is how far you travel with each pull. It is the clearest single number for efficiency, and raising it is usually faster money than raising your turnover.

The engine of DPS is the catch. Instead of pushing your hand straight down, reach forward, then bend at the elbow so your fingertips point at the bottom while your elbow stays high near the surface. Now your hand and forearm form one big paddle. Anchor that paddle and pull your body past it, finishing the stroke all the way back to your thigh. A short finish throws away free distance.

Rotation multiplies this. Let your body roll toward each pulling arm so your back and core drive the stroke, not just your shoulder. For a full breakdown of the pull path, see freestyle swimming technique, and to stop losing your line every breath, drill freestyle breathing technique.

How to measure it: count your strokes per length (SPL) at an easy, controlled pace. Then try to hold the same pace with one or two fewer strokes. When you can, you have made every lap cheaper.

Pool length	Efficient SPL (freestyle)	What it signals
25 yards	14–18	Strong catch and long body line
25 yards	19–24	Average; look for a fuller finish
25 meters	16–20	Efficient for the longer length
50 meters	32–40	Good rhythm over distance

These are rough targets for adult recreational swimmers, not elite marks. Taller swimmers naturally take fewer strokes, so track your own number over time rather than comparing to a friend.

Turn Every Wall Into Free Speed

Every wall is speed you already paid for. Waste it and you have to rebuild it with effort; keep it and it is free. This is why turns are one of the biggest overlooked gains for lap swimmers.

A strong push-off starts in a tight streamline: arms squeezed behind your head, one hand over the other, biceps hugging your ears, whole body rigid like a torpedo. Push off around a foot below the surface, hold the line, and let the wall’s momentum carry you two to four feet before your first stroke. Surfacing instantly wastes the fastest part of every length.

For the turn itself:

• Flip turn: approach without stalling, tuck into a fast somersault, plant both feet, and drive off. Do not glide into the wall.
• Open turn: touch, tuck your knees under you quickly, rotate, and push. Keep it compact instead of standing up.

Add just a foot of streamline to each wall of a 500 and you can save several seconds without getting one bit fitter.

Layer In Tempo Last

Once your stroke is long and your walls are tight, tempo is the multiplier. Raise your stroke rate too early and you just splash faster; raise it after fixing length and you convert efficiency into real speed.

The pro move is to lift tempo while holding your stroke count steady. If your SPL climbs as you speed up, your stroke is shortening and slipping, so you are working harder for less. A cheap tempo trainer that beeps at a set interval helps you feel this, but a stopwatch and stroke counting work fine.

Train speed with short, fast repeats: 25s or 50s with generous rest so you can hold near-top speed and clean form. This teaches your body to move fast without falling apart, which steady mileage never does. For a full progression, follow the tips to swim faster over distance alongside your regular sets. If you are returning to the pool after years away, learning to swim as an adult covers pacing your comeback so speed work does not wreck your form.

Put It Together in a Weekly Plan

Speed is built with a handful of focused sessions, not endless tired laps. Two quality swims a week beat five sloppy ones. A simple structure:

1. Warm up 300–500 easy, mixing swim, kick, and drill so your catch wakes up.
2. Technique block: 4–6 drills targeting one weakness, such as catch-up or single-arm freestyle for DPS. New swimmers can pull from swimming drills for beginners.
3. Speed block: 8–12 x 25 or 6–8 x 50 fast, with rest long enough to hold form. Count strokes on every rep.
4. Turn practice: a few lengths where the only goal is a tight streamline and a clean wall.
5. Cool down 200 easy while you mentally review what felt fast.

Keep one metric per session. One week, chase a lower stroke count. The next, chase a faster 50 at the same count. Because you are measuring, you will know a change worked instead of guessing.

Speed rewards patience. Cut drag, lengthen the stroke, own the walls, and add tempo in that order, and the clock moves on its own. If breathing is what breaks your rhythm when you push the pace, fix that foundation with how to breathe while swimming before you chase another second.
