I call them "exercises", and a set of them "training session" in my Apnea Training Manager. I think that limiting your training to just a single table is not sufficient. In our club we use to train statics twice a week in an hour long training sessions. But of course, you can make more of them, especially if you do not make any dynamic training. Our hour session consist of warm up and several exercises - those are often very different, depending on the instructor who coaches the training (we have about a dozen of them in the club), and on the level of trainees. Sometimes it is more techniqueoriented, sometimes more hypercapnic, sometime more hypoxic, sometime just searching comfort, or being playful, sometime searching big suffering, and sometimes trying to approach the max. Only about twice a year we go for a max under strict safety supervision (competition like). Plus real competitions, of course, for those who want to participate.
Some of the sessions comprised of several exercises are listed in the Apnea Training Manager (linked in my signature). What I like the most, and what I use as a reference to see my progress, is a session called "Cyrnéa - classic mix" in the ATM - warm up, relatively aggressive hypercapnic table (ending with three breath-hold with minimal 15s breath-up), and then after a short rest a hypoxic table.
