Three weekends, properly spaced, will take most physically capable adults from “never freedived” to a recreational diver holding a clean 32-meter line. The actual progression looks nothing like Instagram makes it look. Here is the honest map.
The two systems you should know.
Two cert systems dominate the freediving world right now: AIDA and Molchanovs. SSI Freediving and PADI Freediver mirror AIDA’s structure with their own branding. Apnea Total operates as a school-as-agency model. The vocabulary differs slightly across systems but the progression is essentially the same.
What follows is mapped to AIDA’s structure — the most widely available framework — with Molchanovs equivalents in brackets.
AIDA 1 — Introductory Freediver. [Molchanovs Wave 1 — entry portion.]
Pool only. Two days. The goal is to introduce the physiology, the safety protocol, and the basic skills without ever leaving controlled water. You will learn:
- The breathe-up — the relaxation breathing sequence before a hold.
- The recovery breathing — the hook breaths immediately after surfacing.
- Static apnea — a two-minute breath-hold floating face-down in the pool. Most fit adults reach this on their first attempt with proper coaching.
- Dynamic apnea — a 30 to 40 meter horizontal swim on one breath.
- Buddy protocol — the one-up-one-down rotation, the rescue from below the surface, the airway protection at the surface.
No depth. No open water. Maximum depth is 16 meters, but most AIDA 1 courses never even put a diver below the surface in any meaningful way.
This is where you find out whether the sport is for you. Some people love the stillness immediately. Some find the breath-hold sensation deeply uncomfortable and decide once is enough. Both are legitimate. Either way, two days in the pool is the right way to find out before you pay for international travel and four-day open-water courses.
AIDA 2 — Freediver. [Molchanovs Wave 1 — open water portion.]
Pool plus open water. Three to four days. This is where most recreational freedivers actually begin. The course requirements:
- Static apnea — minimum 2:00 hold. Most pass at 2:30 or better.
- Dynamic apnea — minimum 40 meters distance with fins.
- Constant weight (CWT) — minimum 16 meters depth.
- Rescue scenarios — surface and underwater rescues from 10 meters depth.
The 16-meter depth requirement sounds modest until you do it. That is the depth at which most novice divers first feel the squeeze begin — the chest compression as the lungs reach 50 percent of their surface volume. It is also the depth at which equalization technique starts to matter. The Frenzel maneuver — using the tongue and throat to push air into the eustachian tubes — is what every freediver above this level uses. Valsalva (the ear-popping equalization scuba divers use) does not work past about 20 meters.
What you walk away with: a card that says you can dive recreationally to 20 meters with a buddy, a basic understanding of how your body reacts under pressure, and the discipline of buddy protocol drilled into you by then end of the course.
Most divers who take AIDA 2 in a place like Roatan, Dahab, or Amorgos finish the course doing dives at the requirement depth, not above it. That is normal. The numbers come with reps, not with one course.
AIDA 3 — Advanced Freediver. [Molchanovs Wave 2.]
Four to six days, with significant assumed pool fitness from AIDA 2 work between courses. Requirements:
- Static apnea — minimum 2:45 hold.
- Dynamic apnea — minimum 55 meters distance.
- Constant weight — minimum 24 meters depth.
- Free immersion (FIM) — same depth.
- Variable weight rescue — recover an unconscious diver from 20 meters depth and surface them.
This is the level where you become genuinely useful in the water. You can dive deep enough to do meaningful recreational freediving — wall dives, drop-off dives, swimming with manta rays at cleaning stations, working with photographers. You are trained to rescue another diver in the kind of scenario that actually happens. You have spent enough time on a line to understand how your body responds to repeated depth in a single session.
This is also the level at which a real conversation about progression starts. Some divers stop at AIDA 3 and never train deeper, content to dive recreationally for the rest of their lives at 20 to 24 meters. Others start eyeing the 32 to 40 meter range and the AIDA 4 cert. Both are legitimate. The deeper you go, the more the sport becomes about psychology and equalization technique rather than fitness or breath-hold capacity.
AIDA 4 — Master Freediver. [Molchanovs Wave 3.]
Worth mentioning even if most divers will not reach it. Requirements:
- Static apnea — minimum 3:30 hold.
- Dynamic apnea — minimum 70 meters distance.
- Constant weight — minimum 32 meters depth.
- FIM — minimum 24 meters.
- Variable weight rescue — from 25 meters.
- Significantly expanded theory work on physiology, dive planning, equipment.
32 meters is the depth at which a freediver passes the point of neutral buoyancy on the descent and starts free-falling. The body goes from active swimming to passive falling at around 20 meters with most weight configurations. By 32, the fall is established and the diver is essentially gliding deeper with no propulsion required. The body is also at a fraction of its surface lung volume — around 25 percent at 30 meters. Pressure has measurable effects on the heart rate, the spleen contraction, the entire mammalian dive reflex.
This is the cert that takes you out of recreational freediving and into the territory where the sport demands real training between trips. The athletes who reach this level are typically training in a pool two or three times a week and doing open-water sessions at least monthly.
The Molchanovs alternative — Wave 1, 2, 3.
Same progression, slightly different framing. Wave 1 maps roughly to AIDA 1 plus the entry portion of AIDA 2 — pool plus introduction to depth, with depth requirements around 20 meters. Wave 2 maps to AIDA 3, with depth requirements around 30 meters. Wave 3 maps to AIDA 4, with depth requirements around 40 meters.
The Molchanovs system emphasizes equalization technique earlier and more rigorously. Many serious freedivers prefer it for this reason. If you have a choice between an AIDA-only school and a Molchanovs-certified school, the Molchanovs path is generally regarded as more technical and produces stronger divers — though “stronger” here means more refined, not deeper. The actual depth requirements at each level are similar.
The thing nobody tells you — pool sessions matter as much as open water.
The Instagram version of freediving is all open water and big depth numbers. The reality of training is that the bulk of the work happens in a pool.
Static apnea tables — repeated breath-holds with structured rest intervals, designed to either build CO2 tolerance (short rests, long holds) or hypoxia tolerance (long rests, increasingly long holds) — are the foundation of every serious freediver’s training. You can do them in a pool, in a bathtub, on your living room floor. Most elite freedivers run a static program two to three times a week, off-season, indefinitely.
Dynamic apnea — laps in a 25 or 50 meter pool — is where you build the propulsion economy and the relaxed kicking style that translates to depth work. A diver who can do a clean 75-meter dynamic in the pool has built the cardiovascular and muscular efficiency to handle a 30-meter descent and ascent without burning oxygen on inefficient kicks.
Open-water sessions are the application. Pool sessions are the practice. Treat them with equal weight.
The buddy rule is not optional.
Repeat this until it stops feeling redundant. You do not freedive alone. Not in a pool. Not at the beach in front of your hotel. Not for a quick dive to look at something interesting.
One up, one down. Always. Two divers in the water, only one diving at a time. The diver at the surface is watching the diver below, ready to descend to depth if the divetime runs long, and ready to handle an LMC or blackout at the surface when the diver returns.
The cert courses drill this for a reason. The fatalities in the sport — almost without exception — involve solo divers. The protocol is not a guideline. It is the protocol.
If you cannot find a buddy, you do static at home on dry land — face up, on a couch, with no risk of drowning. That is the only solo training that is safe. Everything else waits for a buddy.
