Inside the Underwater Squad

A training community of freedivers, spearos and mermaids who post their sessions, their wins and their plateaus. New PBs go up most weeks.

Individual results. Progress depends on starting point, consistency and health — not everyone doubles their hold in two months.

What members are posting

Wins, logs and the messy middle

Max Progressive 3:30. First 4:00 with a live replay. A 2:00 that finally felt easy. The Wins feed is a running record of what the training looks like for ordinary people with jobs and families.

Weekly live training

Train along with the group in real time. Can't make it? The replay goes in the classroom and members use them for months.

Member training logs

See the sessions behind the numbers — including the weeks where nothing moved and what people changed.

Answers from Gert

Questions get answered by a freediving instructor, not by a forum guessing. Plus Gert's own training notes.
