Is Swimming With a Kickboard Good Exercise? Benefits and Limits

By Colin Foster

Updated November 2026

Yes, swimming with a kickboard is good exercise, especially for building leg endurance, hip flexor strength, and aerobic capacity. It is less effective for total-body conditioning, because your arms and core are mostly resting. Used deliberately, a kickboard can turn a basic kick set into a solid cardio and strength workout.

Why Kickboard Work Builds Fitness

When you kick with a board, your legs carry the entire load. Your heart rate rises because the large muscles of the thighs, glutes, and hips are working continuously over the length of the pool. Holding the board in front of you also keeps your upper body fixed, so the work is concentrated in your lower body. That makes kickboard sets a useful tool for swimmers who want to strengthen their kick without relying on their arms.

Kicking also trains aerobic endurance. A set of 6 x 100 yards at a steady pace can keep your heart rate in a sustained aerobic zone for twenty minutes or more. Many coaches use kick sets for exactly this reason: they let you accumulate meaningful volume while your upper body recovers.

Factors That Affect How Much You Get Out of It

The benefit of a kickboard workout depends on several variables. Some matter more than others.

Kick style. A flutter kick from the hip, with a slight knee bend and relaxed ankles, works the quads and hip flexors. A kick that starts at the knee or uses a stiff ankle tends to fatigue the calves quickly and does less for propulsion.
Board position. Holding the board with arms extended and shoulders relaxed keeps your body horizontal. If your hips sink, your legs work harder against drag, which can be useful but also increases the risk of poor technique.
Intervals. Continuous kicking builds endurance, while kicking 25s or 50s with short rests builds speed and power output.
Breathing. Because your arms are fixed, breathing rhythm becomes a key element. Bilateral breathing every three kicks is a common approach for beginners.

Limits to Keep in Mind

A kickboard does not work your shoulders, back, or core in the way a full stroke does. Kicking alone also offers little resistance training for the upper body, so it will not improve pulling strength. If your goal is complete swim fitness, kick sets should be one part of a balanced session that includes pulling, drills, and full-stroke swimming. Swimmers with knee or hip problems should also consult a physical therapist or doctor before adding high-volume kicking.

Practical Tips for Better Kick Sessions

Warm up with 200 to 300 yards of easy swimming before starting kick work.
Keep your kick small and fast. Aim for a relaxed, quick rhythm rather than large, slow splashes.
Start with 4 x 50 yards at moderate effort, then build to 8 x 50 or 6 x 100 as your legs adapt.
Rest 15 to 20 seconds between 50s and 20 to 30 seconds between 100s to keep quality high.
Film or ask a coach to watch your kick once a week to catch knee bend or ankle issues early.
Finish with a few full-stroke lengths to reconnect your kick with your arms.

What We’d Use

A standard foam kickboard is the most common choice for pool training because it is stable and easy to grip. For swimmers who want more structured kick work, a kickboard with a larger surface area can help beginners stay flat in the water.

How many calories does kickboard swimming burn?

Calorie burn depends on body weight, pace, and duration. Kicking at a moderate effort burns energy at a rate similar to other moderate aerobic exercise, but exact figures vary widely, so treat any estimate as approximate.

Is kickboard work good for beginners?

Yes. It helps new swimmers learn balance, breathing timing, and kick mechanics without the coordination demands of a full stroke.

Can I lose weight with kickboard swimming alone?

Weight loss depends on overall energy balance, including diet. Kickboard sessions can contribute to a fitness routine, but results vary by individual.

How often should I do kick sets?

Many swimmers include kick work two to three times per week. Start lighter if you are new to swimming, and increase volume gradually to avoid knee or hip strain.

Does a kickboard build leg muscle?

It builds muscular endurance more than large muscle mass. Adding resistance or fins can increase the training stimulus for stronger legs.
