​The last few weeks I've been practicing my breathing with an app called STAmina. I was advised to follow the CO2 breathing sequence which will help build up resistance to the bodies natural warning of CO2 build up. I started on the app with 0:45 second breath holds, 1:00 minute breath holds, then worked up to 1:25. My breath holds are currently 1:25 and breathing sections starting from 1:30 and decreasing by 5 seconds to 0:55. It's 8 cycles and the total time of the exercise is 20 minutes.

One thing I noticed was that it was important to be relaxed with no interruptions. If I got interrupted then even at the first 15 seconds of my breath hold I'm thinking that I won't manage it, and towards the end of the hold it was starting to become uncomfortable. I had the app setup to beep every 15 seconds which seemed to help really well, as its difficult to judge how much time has passed. I've notice in the past that it can sometimes be difficult to judge time when relaxed. It currently feels good to know the elapsed time, but I can also see how it could be off putting as well.

In a few days I'll be in Malta with One Breath Freediving. So I need to keep up my breathing exercises and finish the last few pages of the AIDA2 manual.

Before doing any training I thought I may be able to hold my breath for 1 minute. But following the course manual and the breathing app I've surprised myself that I can do 8 cycles of 1:25 breath holds.

I'm a bit nervous about some aspects of the course. As a scuba diver I know I'm more comfortable and relaxed when under the water, rather than on the surface, so I'm currently wondering how well I'll be able to relax on the surface. I think of the transition between the surface and underwater to be the risky area when scuba diving..... probably due to possible kit issues rather than physical ability. Also, on the surface I feel more exposed and vulnerable and this only seems to be the case in the sea. Once under the water it's peaceful and calm.

Another issues is the feeling of being underwater on just a breath hold. Being at 15m without an air supply is very dangerous situation when scuba diving but is perfectly normal and safe when freediving. Although I held my breath when in a pool or snorkelling in the sea and felt ok
