I set a goal for the end of this year: 4 minutes. Last night I held for 4:07!!!!! Apnea Walking is what helped me make the most impressive gains. I do sets of 35/50/75. I just got hooked up with some CO2 tolerance tables and that is sort of my Holy Grail of information. They helped, but I haven't had them long enough to imagine what effect they would have had.

Thanks to all of you for the knowledge you impart on us newbies.

Congratulations Tim!
I am going to have to give that Apnea Walking thing a try. I did 4:30 back in October then had flu and some other illness and haven’t been close since.
