Quick update - I've been practicing a lot in the last 3 months and my speed improved significantly. I went from 2:05-2:10/100m to 1:52/100m (for 500m).
But when I look at my stroke video, it seems like there is still a lot of improvement. I would love to hear your feedback on what I should focus on next.
Here is my new stroke video.
This was my stroke video from Feb/Mar
In the last 3 months, I focused on 2 things - head position and high-elbow catch. I think I made significant improvements to the head position but high elbow catch still seems elusive.
