Does the type of cardio that you recommend for your members vary, or do you
determine the optimum type of exercise for them individually?

If so, how do you determine the type of exercise?

I find that running has the greatest effect on my general wellbeing, but have
not yet found an exercise that stops me being a hoover (unless I skip-breathe,
but I have been told that that is not a good idea). Could it be the amount that
I do is not enough (30mins 3 times per week). I have also tried lots of
underwater swimming, and have daily access to a pool,

thanks in anticipation of your experience (fawn, fawn),

          John, I am not sure what to say here. Either you have not been doing 
the exercise long enough (as in for many months or years), or you are still 
nervous about diving (as in a new diver). All new divers are usually hoovers
for 
a while, this goes away. The other takes a lot of time, ans you wil not see 
results for a while. You will get better at consumption under load, but not 
necessarily under stress. Deeper breaths work better to remover CO2. You have 
plenty of oxygen, it is the co2 that is hard to get rid of, and better done by 
the cariovasclarly efficient diver or athelete. 

           All I can say from my experinece is that you must do it every day, 
and you must push pretty hard to get improvement - most people will not do
this. 
As you have noticed, however, the overall feeling of being in condition is 
itself worth doing it for, not to mention the major health benefits.

            Another trick, and this is only for those who may need it, is to do 
hypoxic stuff, but be sure there is somebody watching you, like a lifeguard. 
This should follow a set of hard stuff, so you are a little on the streessed 
side. Do repetitive hypoxic sets, and it will hurt, but it will work. Then try
, 
while diving, seeing how long you can go on a bottle once it fisrt shows signs 
of drawing hard, to get used to what an out of gas situation would be, and how 
far or long you have to work it out without losing your relaxed  status. I 
always do this with each bottle or deco bottle , while checking to be sure my 
backup is working . Again, hypoxic stuff is real dangerous, and is only good 
inconjunction with normal stuff.
