What a boring picture. All fellow cave divers and wannabees look like that. A big downside of that diving position is that then one needs to spend time on the elliptical trainer at the local gym. Become more vertical in the water and you will get all the aerobic excercise, upto exhaustion, that you'll ever need.
Just drop the gym and dive like this
(it's me & my instructors fishing net; dive #205; yeah - we had a bit of fun)
