I have the lofty goal of being able to go 50-100 LCM fly without toys. I can currently go about 25 yards. Can anyone help me devise a plan day by day of what to do to strengthen my shoulders/body enough to be able to do this? I do have fairly good rhythm - I used to race the 200 fly as a kid & can still kick fly well, and of course, I am most impressive when I wear my little zoomers - but even with zoomers, my arms start to die, and then I run out of breath around 37.5 meters. Any great ideas out there? Thanks!
