I've just discovered the wonders of doing negative statics! I was reading about them on these forums and decided to try a couple while sitting here at my computer at work. I did a quick one minute breath-up of deep regular breaths, blew all my air out and did a reverse pack and got 34 seconds before breathing again. Not that impressed, so I did it again and this time got 1 minute and 10 seconds! So I did another quick breathup and got a 3:30 breath-hold, which is not bad considering my pb is 4:05.
I think I'll use negative statics (dry) before freediving in future - very handy tool for a quick warm-up.
 
Careful applying this in the water. The only time that I ever experienced haemoptysis was about three weeks ago while doing negatives w/o sufficient warm up. I was practicing mouth-fills and went too deep too fast w/ empty lungs.

Oddly enough, the coughing started pretty soon after the dive, but the bloody fractions took about 15 minutes to appear.

It was a pretty minor squeeze and I seemed to be back to 100% w/in about a week.
