Yes, two minutes is far to long for a breath-up at a CO2 table, on my mind. Makes no sense to me, unless you use the first breath holds like warm up. In our club we always start the static session with two or three expiratory breath holds - relaxing and slowly blowing out air (under water) for 1 or 2 minutes (or whatever you can do relatively comfortably), and then possibly some empty lungs breath holds for the warm up.
We do hypercapnic tables as follows:
BU = Breath Up
APNEA = ~60% of your max; novices usually start with something like 1:30 - 1:45, so possibly more than 60% of their max, which is usually not too high at the beginning.
- APNEA + 1:30 BU
- APNEA + 1:15 BU
- APNEA + 1:00 BU
- APNEA + 0:45 BU
- APNEA + 0:30 BU
- APNEA + 0:15 BU
- APNEA + 0:15 BU
- APNEA + 0:15 BU
- APNEA - end
And even that is little bit too long, so the more advanced members usually start with just 1 minute and then do 2 more rounds with 15 secs breath up's at the end instead of it. EDIT: The last few breath holds should be really
very difficult. If they are not, increase your apnea time next time.
