I have been working on my kick more but its still weak - 60 seconds for a 50. If I am swimming distance I drag my feet for mere stabiliy. Am I just lazy or should I be kicking away?
Definitely body position. The reason they tire quickly without a pull buoy is their legs sink and they have to kick hard to keep their legs up. They probably aren't even getting effective propulsion from their kick.
I agree with Kirk on this. By body position (alone) they are going to have to work on their core, because with little or no kick, the core is going to have to keep the alignment for them.
