After the previous excellent help I received from my 40m thread I thought I would ask you to help on my next hurdle.

I have completed a 115m dynamic, 45.7m constant weight and the next hurdle is a 5 minute static. Our freediving club has a concept known as the 145 club which involves breaking a 100m dynamic, 40m dive and 5 minute static. I have overcome two of those hurdles and now it is the time for my final one.

I have only tried two wet statics, the first of which was 3m30s which left me on the verge of samba (still clean but I could feel it coming on) and a second three days later doing 4m05s which felt much much better. The longer static I had the guidance of a good friend who has done 7min+ statics before, hence the large increase in time.

Warmup was a 2min dry static, 2 min rest, 2m30s dry static then 3min rest dry then 2 min breathing up in the water. Then I attempted the max static.

To increase i've been doing a few tables, about one each day. What i'm after is tips on reducing my heartrate, breatheup and warmup techniques. In the first 1min I can feel my heart thumping away like mad, burning up my oxygen. First contractions occur at about 1m45s-2m.

Thanks in advance guys!
