What technique assists divers in achieving a balanced body position underwater?

Relaxed breathing is essential for divers to achieve a balanced body position underwater. When divers practice relaxed breathing, they are able to control their buoyancy more effectively. This technique involves taking slow, deep breaths, which not only helps in stabilizing buoyancy but also promotes a calm and steady body position in the water. By allowing the body to naturally float at a neutral buoyancy level, divers can remain more horizontal and balanced, reducing the chances of unwanted movement or instability.

In contrast, quick movements can lead to unnecessary changes in buoyancy and position, while staying tethered may limit a diver's range of motion and freedom to maneuver. Using weights can help manage buoyancy but doesn't contribute directly to the overall balance achieved through proper breathing techniques. Thus, while all aspects of diving contribute to performance, relaxed breathing is the key technique for maintaining a balanced body position underwater.
