Freediving is the most natural way to explore underwater. No heavy equipment. No bubbles. Just one breath.

This guide is your step-by-step introduction to the sport, built to take you from your very first questions through to advanced techniques and training.

• Freediving means diving on a single breath without scuba equipment.
• It combines adventure with relaxation and focus.
• Beginners start with courses from agencies like AIDA, SSI, or PADI.
• Essential kit: mask, snorkel, fins, wetsuit, weight belt.
• Safety is central: never dive or train alone.
• The guide covers 21 parts: history, physiology, skills, safety, training, and going pro.

Never freedive or practice breath-hold training alone.  Always dive with a trained buddy.

How deep can beginners go?
Most beginners reach 10–20 m (33–66 ft) safely with training.

Do I need to be very fit?
Good health and swimming confidence are more important than fitness. Courses build ability step by step.

Is freediving safe?
With proper training, a buddy, and conservative depth progression, freediving is safe. Risks mainly arise when divers push too far or dive alone.

What’s the first step?
Take a beginner course from a recognised agency and practice breath-hold relaxation exercises.
