Alex is rowing well with pretty good length. Very close to proper body sequence -- using legs at catch and delaying opening of back. Chris, Mike and Mark all using the back too early (pause video to see).

Alex is leaning slightly away from rigger at finish (again, pause to see). If you feel "pinned" at finish and half to lean away to extract blade, move your foot stretchers towards the bow a few notches. This will give you more clearance, but might decrease your length at the catch.
