Freediving - Apnea

Take your snorkeling to new depths on one breath by learning the fundamentals of freediving. Not only does freediving allow you to experience the underwater world in a bubble-less environment - it also can allow you to explore depths hard to reach by scuba.

During your open water sessions, you will learn proper breathing techniques, familiarize yourself with diaphragm breathing and take a deep breath like you never have before. You will develop the skills necessary to train your body to be more efficient, gain better respiration and muscle flexibility, and learn new skills to feel comfortable and confident about traveling to depth.

Training Techniques Pool Sessions (with optional specialty Certification)

Let's face it, Colorado is a landlocked state, with few options to practice freediving to depth, but that does not stop our community of amazing freedivers from growing! We have developed a unique opportunity for all our freedivers to come practice their skills in our pool on a regular basis during our Training Techniques Pool Sessions.

Instead of a more open and fluid pool session, we have decided to create specific sessions designed to help you improve your skills in a certain area or discipline. And if you attend three different pool sessions and the Training Techniques seminar, you will become certified in the Training Techniques Specialty program from SSI!

You must have completed at least the Freediving Pool (Level 1 Class and Pool) Course to participate in our pool sessions. BUT, our Level 1 Class and Pool tuition includes two free pool sessions!


Training Techniques Specialty Certification Requirements:

  • Attend a Training Techniques Seminar: During this two hour course, we will go over stretching for freediving, training tables, and ways to improve your freediving when water is not available.
  • Attend at least three different Training Techniques pool sessions: We have developed a variety of different types of pool sessions. If you attend three different sessions, you will receive your specialty certification!


Training Techniques Pool Session Descriptions:

Static Apnea: Learn mindfulness and meditation relaxing techniques to improve your breath-hold time. You will also learn how to increase your carbon dioxide tolerance during our static sessions.

Dynamic Training: Train with our instructors on dynamic tables, including standard tables, pyarmid tables, and timed tables. Don't worry - they are actually very fun!

Personal Best Session: Work on the different disciplines in dynamic apnea and static apnea and increase your distance & times dramatically. Streamlining and weighting techniques will be the focus, as well as visualization and breath-hold techniques.

Pool Depth Practice: Get ready for your open water sessions by practicing your duck dive, streamlining techniques, clearing techniques, and training table simulations. This is best for those who are getting ready for open water diving.

What is Freediving?

Freediving aka Apnea aka Skin Diving aka breath-hold diving is a form of underwater exploration that does not use the assistance of a breathing apparatus such as scuba gear. There are many disciplines within the sport, with constant weight diving being the most popular.


Disciplines in Freediving

Dynamic Apnea (DYN): Swimming horizontally underwater striving for a distance goal.

Dynamic No-Fins Apnea (DNF): Swimming horizontally underwater without the aid of fins striving for a distance goal.

Static Apnea (STA): Holding your breath while floating head down in water striving for a time goal.

Constant Weight Apnea (CWT): Swimming vertically to depth and back underwater striving for a depth goal.

Constant Weight No-Fins Apnea (CWT): Swimming vertically to depth and back underwater without the aid of fins striving for a depth goal.

Free Immersion (FIM): Diving vertically to depth and back underwater by pulling yourself down a line and striving for a depth goal.

Variable Weight Apnea (VWT): Diving vertically to depth with the use of weight, then swimming back up or using a line and pulling yourself to the surface. Again, the goal is depth.


Where Can I Freedive?

The short answer to this question is everywhere there is water! But, in Colorado we are limited in the places we can find water deep and safe enough to truly practice freediving, so we travel to gain these depths and find fun places to practice our sport.
