I've studied good rowers on the erg in YouTube and similar videos, and what stands out in contrast to me is the leg drive > back sway > arms phases are smooth but clearly distinct. That is, the legs are straightened then the upper body is leaned back and finally the arms are used. My technique blurs those phases and my legs come to the fully straightened position only shortly before my arms reach my chest. My attempts to fix it feel unnatural (jerky) and I quickly revert to my old form. Any tips or tricks for addressing the problem?
Please help
