Kick Buoy: Understanding, Proper Use, and Benefits for Swimmers

By Hart 8 min read

A kick buoy is used by placing it between the thighs to provide buoyancy to the legs, allowing swimmers to focus on upper body strength, refine arm stroke technique, and improve body alignment during swim training.

How do you use a kick buoy?

A kick buoy, or pull buoy, is a piece of swim training equipment used to provide buoyancy to the legs, allowing swimmers to isolate and focus on upper body strength and technique, or to concentrate on improving kick mechanics without the added drag of sinking legs.

Understanding the Kick Buoy: What It Is and Why It's Used

The kick buoy is an hourglass-shaped piece of foam designed to be placed between the legs. Its primary function is to provide flotation to the lower body, effectively elevating the hips and legs in the water. This elevation counteracts the natural tendency for many swimmers' legs to sink, which often occurs due to weaker core engagement or lower body density.

  • Definition and Purpose: By floating the legs, the kick buoy reduces the need for constant kicking to maintain body position. This isolation allows swimmers to:
    • Focus on Arm Stroke: Concentrate on pull mechanics, hand entry, catch, and finish without the distraction of maintaining leg position.
    • Develop Upper Body Strength: Engage and strengthen the lats, shoulders, chest, and core more intensely.
    • Improve Body Alignment: Experience a more streamlined, horizontal body position, which can then be mimicked during regular swimming.
    • Isolate Kick Training (when used differently): While primarily for upper body focus, it can also be used with a kickboard to enhance kick focus by providing stability and buoyancy, allowing for greater power generation.
  • Anatomical Focus: When used for its primary purpose (pulling), the kick buoy shifts the workload significantly to the upper body musculature (latissimus dorsi, deltoids, pectorals, triceps, biceps) and the core stabilizers (rectus abdominis, obliques, erector spinae) to maintain a long, powerful stroke and a stable body line.

Proper Placement and Technique for Optimal Use

Effective use of a kick buoy requires correct placement and an understanding of how it influences your body dynamics in the water.

  • Standard Placement: The most common and effective placement is between the thighs, just above the knees. This position provides optimal buoyancy to lift the hips and legs, creating a more streamlined body line while allowing for some natural leg movement and core engagement.
  • Alternative Placement (Optional): Some swimmers, particularly those with very strong kicks or looking for less buoyancy, might place it between the ankles. This provides minimal lift and demands more core stability, effectively making the legs a single, buoyant unit. This is less common for general training.
  • Body Position and Alignment:
    • Horizontal Line: Aim for a flat, horizontal body position, with hips and shoulders level with the surface of the water. The buoy should help achieve this.
    • Head Position: Keep your head in line with your spine, looking slightly forward and down. Avoid lifting your head excessively, as this will drop your hips.
    • Core Engagement: Actively engage your core muscles to maintain stability and prevent your lower back from arching. The buoy provides passive lift, but active core engagement is crucial for a stable, powerful stroke.
  • Kick Mechanics (or lack thereof): When using the buoy for upper body focus, the legs should remain relatively still, not actively kicking. A slight, passive flutter or "balance kick" may occur naturally to maintain stability, but the goal is to minimize propulsive leg action. Focus on a long, strong pull through the water with your arms.

Key Benefits of Incorporating a Kick Buoy into Your Training

Integrating a kick buoy into your swim routine offers several physiological and technical advantages.

  • Enhanced Upper Body Strength and Endurance: By eliminating the need for propulsive kicking, the arms and shoulders bear the full responsibility for propulsion. This intensifies the workout for these muscle groups, leading to increased strength and muscular endurance specific to swimming.
  • Improved Pull Technique: Without the distraction of kicking, swimmers can concentrate solely on the intricate details of their arm stroke: high elbow catch, effective hand entry, powerful pull-through, and controlled finish. This helps to ingrain proper neuromuscular patterns.
  • Core Engagement and Stability: While the buoy floats the legs, maintaining a streamlined body position still requires significant core engagement. It forces the swimmer to activate the deep abdominal and back muscles to prevent the body from snaking or swaying, thereby strengthening the core's role in propulsion and stability.
  • Upper Body Recovery/Focus: For swimmers with tired legs, or those recovering from a lower body injury, the kick buoy allows for continued cardiovascular and upper body training without stressing the legs.
  • Pacing and Rhythm Development: By simplifying the propulsive elements, swimmers can focus on maintaining a consistent stroke rate and rhythm, which is crucial for race strategy and long-distance swimming.

Common Mistakes to Avoid

While beneficial, improper use of a kick buoy can hinder progress or reinforce poor habits.

  • Over-Reliance on the Buoy: Using the buoy too frequently can lead to a dependency, where swimmers struggle to maintain proper body position without its assistance. It should be a tool for specific training goals, not a permanent crutch.
  • Improper Body Position: Even with the buoy, some swimmers may still allow their hips to drop or their back to arch. The buoy aids, but does not replace, the need for active core engagement and proper body alignment.
  • Neglecting Core Engagement: Thinking the buoy does all the work for stability is a mistake. A slack core will lead to a "fish-tailing" motion, reducing efficiency and negating the benefit of streamlined pulling.
  • Using it as a Crutch for Poor Technique: If a swimmer has significant form issues with their arm stroke, simply adding a buoy won't fix them. It provides an opportunity to focus, but direct coaching and conscious effort are still required.
  • Actively Kicking: While a small, passive flutter is acceptable for balance, actively kicking with a buoy defeats its primary purpose of isolating the upper body.

Integrating the Kick Buoy into Your Workout Routine

The kick buoy is a versatile tool that can be incorporated into various phases of a swim workout.

  • Warm-up Drills: Use short pull sets (e.g., 50-100 meters) during your warm-up to activate the upper body muscles and establish a feel for a streamlined body position before full-stroke swimming.
  • Main Set Workouts: Integrate longer pull sets (e.g., 200-400 meters or longer) into the main portion of your workout. These can be focused on sustained effort, tempo training, or specific stroke drills.
  • Cool-down/Recovery: A gentle pull set can be a good way to flush lactic acid from the upper body while allowing tired legs to rest.
  • Sample Drill Ideas:
    • Build Pulls: Start at an easy pace and gradually increase effort over the length, focusing on maintaining form.
    • Negative Split Pulls: Swim the second half of a distance faster than the first, emphasizing pacing and sustained power.
    • Single-Arm Pulls: Use the buoy with one arm pulling and the other extended or resting by the side, to isolate and correct imbalances.
    • Fist Drill Pulls: Place the buoy between your legs and make fists with your hands. This forces a focus on forearm and elbow position, as well as core rotation, by removing the hand's propulsive surface area.

Who Can Benefit from Using a Kick Buoy?

Almost any swimmer can find value in incorporating a kick buoy into their training regimen, from beginners to elite athletes.

  • Beginner Swimmers: Can use the buoy to help establish a more horizontal body position, making it easier to focus on basic arm movements and breathing without struggling to keep their legs afloat.
  • Intermediate to Advanced Swimmers: Benefit from the buoy's ability to isolate and refine upper body technique, build strength, and develop better pacing strategies.
  • Triathletes and Open Water Swimmers: Often have a less dominant kick due to cycling and running. The buoy helps them develop the upper body endurance crucial for long-distance swimming.
  • Individuals in Rehabilitation: Swimmers recovering from lower body injuries can maintain cardiovascular fitness and upper body strength without putting stress on their legs.
