Why is it important to maintain good physical fitness before diving?

Maintaining good physical fitness before diving is crucial primarily because it enables divers to handle the physical demands that come with the activity. Scuba diving requires a degree of strength, endurance, and flexibility. Good fitness enhances a diver's ability to manage their buoyancy, navigate while swimming against currents, and respond effectively in potentially stressful situations underwater.

For instance, ascending and descending requires physical effort, especially if a diver encounters strong currents or needs to control their ascent speed to avoid decompression sickness. Being physically fit also aids in managing equipment, which can be cumbersome, and allows divers to execute emergency procedures more effectively. Overall, a good fitness level directly contributes to safety and the enjoyment of the dive, as divers are better equipped to handle various conditions they may face beneath the surface.
