Hey all, so I'm not super new to freediving, I've always done it while going lobstering or spearfishing(never deeper than 20ft). But I want to go deeper. I plan on taking a few classes in the fall to learn the techniques and stuff, and the first class said most students can achieve 60ft depth, and that the longest breath hold is 3 minutes. Well, I want to get in a lot better shape before doing that, and work on how long I can hold my breath. My static hold(out of water?) is a little over a minute. I've yet to actually time myself underwater yet, but I plan on doing that soon-whenever the next time I'm at my parent's house is(They're the only people I know with a pool). But I was just looking for some advice on training/conditioning your body for deep dives.I plan on cutting dairy and grains out of my diet(I guess that's called the paleo diet..?) and pretty much just eating lean meats with lots of fruits and veggies. I've started trail jogging again, I figured getting better at my cardio will help out a bit. If anybody has any advice, good workouts, diet tips, or breathing exercises, let me know. Thanks much!
