DNF help

[beero1000]

I've started doing dnfs in a 25m pool.

I can do 25m every time, but I really have to overcome the strong psychological urge to just stop there instead of turning around.
My max has been a 50m.

I'm pretty sure I'm not using the proper technique. Im swimming hard and quickly, not gliding like I saw in some of the movie clips on DB. When I try to take it slow and calm, I end up floating up (no weights) and I feel like it takes too long. I can't even do 25m like that.


Also, if i can comfortably do a 25m dnf and strain to do a 40-50m, approx. how deep will I be able to safely go with fins? 10m? 15?

any help and/or tips are appreciateld

thanks,
beero

p.s. I'm off to the pool now. just got my ipod's waterproof casing. should make laps a lot more interesting.

A neckweight will make a huge difference to your glide, comfort and distance. Dynamic nofins is only fun without one if you do it FRC so that you are neutrally bouyant. Goodluck with your training

I have come to like swimming across in the deep end of the pool (4m) for that same reason: The increased water pressure puts me in (almost) neutral bouyancy, which makes the underwater swimming much nicer. AND making a turn every 12m or so takes away the 'psychological issues' of the turn, that you mention.

I usually do a set of 15x3, each dive lasting around 1:10.

Beero,

You need a neck weight. Easy to say, hard to find one, in fact you better make one for yourself. I made mine out of a bike tyre, 2-3kg of lead (buy 1 or 2 small sacks of scuba diving weights that have inside these tiny lead spheres) and an easy to open/close buckle. With the neck weight in place you should be neutral and then you will find the gliding a breeze and very very fun!

It may also help you to train in a 50m pool if you have access to one, this way you are not having hte mental stress of turning at 25m - i know it from own experience! Now i have the same problem at 50m turn in the big pool but aint no 100m pool around!

Hm, for me is more difficult to do DNF in 50m pool then when I do it in 25m. I use the pushing off the side to get more glide on way back and thus it's easier. I don't use neck weights but really try to do as long strokes as possible and wait until I almost stop gliding and then stroke again. In 50m pool I do usually about 14 strokes to make it.
Problem is that I do it in normal pool's open hours and sometimes get a kick from swimmers above me. Not so deep pool, you know.
