What is the most important skill in diving?
One of the most important skills a diver can learn is buoyancy control. Good buoyancy control translates to stability underwater, less exertion and better gas consumption, as well as preventing damage to the reef and marine life. Scuba diving is an effective activity to build muscle strength and improve flexibility. To swim in the water, you must engage the muscles in your arms, legs, and core to maneuver effectively. This continuous effort helps develop lean muscle mass while improving overall muscle strength and endurance.
