I was uncomfortable with My 02 tables this a.m. Table 9 is normally not difficult for me. Yesterday I did hypoxic cardio ie. 30 minute stationary bike with a 30 second breathold every minute and thirty seconds followed by 45 minutes of weight training. I train 5 or 6 days a week with swimming, hypoxic cardio, weight training co2 and 02 tables. I try to line dive or spearfish on the weekends as well.... I think I have slipped into overtraining but I don't want to fall back into the opposite direction either (undertraining). Any advice from someone who's "been there and done that" ?
