How to choose the right kickboard for water aerobics: focus on size and buoyancy

Kickboards in water aerobics aren’t just cute accessories. They’re workhorses that give stability, help you target the right muscles, and keep workouts smooth and safe. If you’re studying for ISSA’s group fitness topics, you’ve probably heard that equipment choices can make or break a session. When it comes to kickboards, there’s a smart rule of thumb: the size and buoyancy matter most. Everything else—color, material, cost—comes after that. Let me break down why.

Size first: fit matters, and fit can make or break a workout

Imagine trying to push through a set with a kickboard that’s too small. Your hands might barely grip it, your wrists could twist uncomfortably, and your knees might drift toward the water line. That’s not just annoying; it’s unsafe and inefficient. On the flip side, a board that’s too big can feel clumsy. You’ll struggle to maneuver it, and you’ll waste energy wrestling with it instead of focusing on form and breathing.

In water exercise, body size and proportion influence what “right” looks like. Taller athletes often need a longer board; shorter athletes may do just fine with a standard size. The goal is a board that sits comfortably in your hands, sits high enough in the water to permit a natural range of motion, and supports your posture without forcing you into awkward angles. If you’ve ever used a board that sits too low or feels like you’re wrestling a surfboard in a pool, you know why this matters.

Buoyancy: how much float you actually get

Buoyancy isn’t a fancy buzzword. It’s the magic that lets you float with ease and control your movements through the water. A well-buoyant kickboard gives you steady support so you can engage your core, stabilize your shoulders, and keep legs moving without fighting against sinking or tipping.

If the board sinks a bit when you rest it on the water, you’ll have to work harder to stay balanced. If it sits high and feels buoyant, you’ll glide through kick sets with less effort and better form. The “just-right” buoyancy is a personal thing. Some people prefer a livelier float, others want a bit more resistance in the water. The key is to test how it feels in your hands and under your chest or forearms while you’re standing or in a shallow part of the pool.

Secondary factors that still matter, just not as much

Color is nice to have, but it won’t improve your workout. If you’re picking a kickboard based on personality or team color, that’s fine—just don’t let color drive a choice that should be based on size and buoyancy.

Material matters, but mostly for durability and grip

Kickboards come in foam, foam-coated plastic, and some harder plastics. Foam boards tend to be softer, lighter, and easy on your forearms, which is great for beginners or rehab scenarios. Harder plastics can be more durable and hold their shape better over time, but they can feel slicker and less forgiving if your grip gets sweaty.

Grip texture also plays a role. A board with a textured surface or ribbed sides can improve your grip when hands are wet. If you’re prone to slipping, look for a surface that gives you a confident hold without needing to squeeze too hard.

Cost is a factor, but quality first

Price can influence your choice, especially if you’re equipping a group or gym space. The important thing is to find a balance: a board that’s affordable but still appropriate for the exercises you’ll be doing. A very cheap board might wear out sooner or fail under repeated use, which isn’t just an expense—it’s a disruption to workouts. Prioritize reliable buoyancy, the right size, and a comfortable grip, then weigh the cost against expected durability.

How to choose: practical steps you can take

• Start with a quick sizing check. If you’re shopping in person, bring your typical workout clothes and stand in the shallow end. Hold the board in front of you and see how it rests against your chest or forearms. It should feel secure without you needing to over-grip. If you’re shopping online, check the product specs for length and recommended user height or torso dimensions.

• Test buoyancy in the pool. If a store allows a test in the water, grab a few options and compare how they float with your body submerged. If you’re in a class or gym, ask a staff member to suggest boards that work well for your height and typical routine.

• Consider your goals. Are you focusing on core stabilization, leg propulsion, or gentle cardio? A slightly larger board with higher buoyancy can support deeper core work; a lighter, smaller board might be better for shorter sessions or beginners easing into movements.

• Think about storage and transport. If you’re a busy student or a trainer moving equipment between pools, a lightweight board that still holds its shape will be more practical.

Using the right board in a workout: practical tips

• Start with posture. Let the board support your forearms or hands while you engage your core. Your shoulders should stay relaxed; don’t hitch them up toward your ears.

• Breathe with intention. Think of your rhythm as you press through the water. Inhale through the nose, exhale through the mouth as you extend your legs and press the board forward. A steady breath helps you stay buoyant and stable.

• Mix it up, don’t over-rely on the board. The kickboard is a tool, not a crutch. Alternate with exercises that challenge balance, flexibility, and mobility. This builds well-rounded fitness and reduces overuse risk.

• Watch for shoulder strain. If you feel shoulder discomfort, soften your grip, and check your form. The board should help you, not irritate you. If pain persists, switch to a gentler movement or a different floatation aid.

Common myths busted (and why the truth matters)

• Myth: Bigger is always better. Truth: The best size matches your body and the exercise. A board that’s too big or too small can hinder movement and stability.

• Myth: Color equals performance. Truth: Color is cosmetic. Performance comes from size, buoyancy, texture, and how it feels in your hands.

• Myth: The cheapest board is fine. Truth: A very inexpensive board may wear out quickly, losing buoyancy and grip. When you’re in the pool, reliability matters as much as cost.

Real-world scenarios to connect the ideas

• You’re a beginner in a community pool, and you want gentle support as you learn to float on your stomach with legs trailing. A mid-sized, fairly buoyant foam board can make that the focus—your breathing, your posture—without fighting gravity.

• You’re rehabbing a shoulder and want to minimize strain. A soft, well-padded board that’s not overly buoyant can help you maintain form while keeping your joints comfortable.

• You’re teaching a multi-level class. A couple of boards of different sizes and buoyancies let you tailor the challenge to each participant, from first-timers to athletes who want more resistance.

Tie-in with ISSA group fitness topics

ISSA’s curriculum for group fitness often emphasizes safe technique, exercise progressions, and equipment literacy. Knowing how to choose the right kickboard is a small but essential piece of the larger picture: it helps you design sessions that are safe, effective, and enjoyable. When you can match gear to the workout goals, you create an experience that people want to repeat. That’s the kind of insight that makes a trainer stand out and helps students connect with clients on a practical level.

A quick recap you can take to the pool

• Primary factors: size and buoyancy. These two shape how stable you are and how easy it is to perform movements with proper form.

• Secondary factors: material and grip, plus durability. They influence comfort and long-term use, but they don’t override the importance of size and buoyancy.

• Don’t worry about color or price alone. Focus on finding a board that feels right in your hands and floats well with your body.

• Test in real conditions if you can. The pool reveals more than a product page ever will.

• Use the kickboard as a tool to support technique, not a substitute for smart movement and mindful breathing.

A friendly nudge: keep the bigger goal in view

Water workouts are about balance, control, and confidence. The kickboard is one helpful partner in that journey. Get the right size, ensure good buoyancy, and you’ll notice more stability, less strain, and smoother progression through your sets. It’s a small choice with a noticeable payoff.

If you’re exploring more about the ISSA group fitness framework, you’ll find that gear literacy, safety cues, and practical technique are recurring threads. The more you understand how equipment works—why certain attributes matter—the better you’ll be at guiding others and designing smart, sustainable sessions. And when you walk into the pool with a board that fits you just right, you’ll feel that calm competence in your stance, your breath, and your rhythm with the water. Now go test a few options, and find the one that feels like a natural extension of you in the water.
