I joined the gym lately which has its own indoor pool that I'm using. I haven't been in a pool since rehab, which was 7 years ago, and that was only really treading water, so now I'm trying to learn to swim again I guess. At the moment Im doing something like the
Elementary Back Stroke, except obviously minus the feet movement(I'm a t6-t7 complete paraplegic).
However, while this stroke is a really good work out, I would also like to vary it somewhat with trying the front crawl. The only real technique I've seen for someone like me is
this, but my results are pretty horrible

. I first tried with a float between my legs like he does in the video, but when I try to position my body flat on the waters surface, I end up with my legs nice and level, but my head/chest submerged below the water, and can't reach up to breath. I don't seem to have the stomach/chest muscles to bring that part of my body level on the water. Without the float is worse, and only my butt sticks up above the water, the rest is submerged.
Does anyone have any advice?
