How much "pulling" should be done by the back, and should the back be arched or straight?
Golly. This one will be all-but impossible to describe, as I've only ever been taught, not taught how to teach. My efforts at getting the family to use a good technique have failed to date.
Try a video, though. I had a quick nose through YouTube and came up with this one...

Luckily, they are showing the what that I mentioned, leaving the arm work until last. *phew*
Bits to remember are:
* keep the back straight, you are pulling with the core muscles, not the spine
* wait until the hands have passed the knees on the back stroke, or you'll have a collision.
* if your knees are not good, you could try with the "quarter slide" as described by that guy. I find that rowing makes my knees move more easily
* I find a comfortable stroke rate to be around 30 for most of the session. Also, the stroke and the back stroke (the term "recovery" is used in that video) should take about the same amount of time. Put those two together and you get a good rhythm which can be marked out by having a clock with a loud tick.
* use the "recovery" period. Take a rest, don't rush it.
* (
most important) do your foot straps up properly. Without your feet well locked in place, you will be fighting to keep yourself on the seat. Do the straps up tight, and then tighten them a bit more. You don't need to be worrying about them.
