Swimming Kickboard: What It Is, How to Use It, and Why It Works

Yes, with one important qualification.

Kickboards are excellent for isolating and developing your kick. They let you feel exactly what your legs are doing, build the specific muscle groups used in swimming, and work on kick timing and technique without the complexity of a full stroke.

The qualification: for some swimmers - particularly those with lower back issues - holding a kickboard out in front can cause strain, because the position arches the lower back. If this is you, a few adjustments help:

• Hold the board closer to your body rather than fully extended
• Try vertical kicking (no board) as an alternative
• Ask a coach or physio whether kickboard work is appropriate for you

For most swimmers, though, kickboards are not just good - they're an essential part of training. Bob Bowman, the legendary coach of Michael Phelps, famously incorporates lots of kick in each training session, believing it to be an essential part of fast swimming.

Kickboard sets are genuinely hard work. The muscles being targeted depend slightly on the stroke, but for freestyle (flutter kick) - the most common - you're primarily working:

• Quadriceps - drive the downkick, the power phase of freestyle kick
• Hip flexors - initiate each kick cycle from the hip
• Hamstrings and glutes - active in the upkick and overall leg drive
• Core and lower back - stabilise your body position throughout
• Calves and ankles - contribute to propulsion, particularly with a flexible ankle

This is why kick sets feel so different from full-stroke swimming. You're isolating a large muscle group and driving it hard with no rest from arm pulling. It's a proper lower body and cardiovascular workout.

For breaststroke kick (using a kickboard in a different body position), you add the inner thighs (adductors) and hip rotators into the mix - breaststroke kick is notoriously demanding in its own way.

Poor kickboard technique is surprisingly common. Here's how to do it right.

Basic Position (Freestyle)

1. Hold the board at the top corners, arms extended but not locked out. Your hands should rest lightly on the board - you're not gripping it hard or pulling on it.
2. Keep your head in a neutral position - looking slightly down and forward, not straight up. Looking straight up lifts your hips and kills your kick efficiency.
3. Kick from the hip, not the knee. The movement initiates at the hip joint, with the knee bending naturally as a consequence. A "bicycle" kick from the knee is one of the most common errors.
4. Keep your feet relaxed and ankles flexible. Pointed toes help, but the real key is relaxed ankles - tense, rigid feet act like brakes.
5. Kick within your body line - your feet shouldn't be breaking the surface dramatically on every kick. Small, fast kicks are more efficient than large, splashy ones.

Common Mistakes to Avoid

• Looking straight ahead or up - this drops your hips and creates drag
• Kicking from the knee - wastes energy, produces little propulsion
• Tense ankles - significantly reduces kick effectiveness
• Holding the board too loosely or at strange angles - causes instability and distracts from the kick

Breaststroke Position

For breaststroke kick sets, hold the board against your chest or extend it with both hands, and kick in the prone (face-down) position. Some swimmers do breaststroke kick on their back, which reduces neck strain, a useful variation.

Indirectly, yes - and significantly so for many swimmers.

Your kick contributes to propulsion, but more importantly, it drives your body rotation in freestyle and keeps your hips elevated. A weak or mistimed kick creates drag and disrupts your stroke rhythm, even if your arms are working well.

Regular kickboard work builds the leg strength and muscle memory to maintain an effective kick throughout a race or long training set - which is where many swimmers fade. You might not feel faster in kick sets themselves, but swimmers who do consistent kick training consistently improve their full-stroke times.

The effect is most pronounced in sprint events, where kick power matters enormously. But even distance swimmers benefit from a stronger, more efficient kick that maintains body position without excessive energy cost.

Yes - the kickboard is one of the most beginner-friendly pieces of swim equipment available.

For someone learning to swim, a kickboard:

• Removes the need to coordinate arms and legs simultaneously while learning
• Provides enough buoyancy to keep a nervous beginner's face out of the water
• Lets them focus entirely on the feeling of moving through the water with their legs
• Builds confidence before progressing to full stroke swimming

If your child is starting swimming lessons or joining a beginner squad, a kickboard is one of the first pieces of equipment worth having. Most learn-to-swim programmes will have them available, but squads will usually expect swimmers to bring their own from a certain age.

One tip for beginners: don't rely on the kickboard indefinitely. Some learners become so comfortable with it that they resist progressing to unassisted swimming. It's a stepping stone, not a destination.
