Keeping Kick and Stroke Connected

Hello everyone, First topic here! I'm a new swimmer (28 male, 6'3" 180lbs) who began back in May with a program called 0-1650. I spent six weeks completing that, and a couple of months after doing individual workouts before moving to a Masters team. We swim 4x a week, and I have a weight lifting routine/core workout that I do 2x a week, non-swimming days. I have made a ton of improvement on all fronts thanks to my coach and team. My technique has improved tremendously, as well as my speed. My coach has often described this progression for me as: 1) we learned how to swim 2) we learned how to practice 3) soon we'll really train. I have my first meet in two weeks, so I'm excited about that! However, one thing that I don't feel I've addressed properly yet, is an overall feeling of connection from stroke to kick. Separately, I feel I'm gaining a lot of competence in the two, but together they just don't work together like I'd expect. For example, when kicking with short fins, I feel I'm always behind in my stroke. I try to speed up, but the stroke just doesn't come together right. I know much of this has to do with core strength. This is something I have lacked historically, but have been working on a lot lately with about 20 minutes of core work at the end of my lifting days. While I've definitely seen improvement in exercises like the plank, I'm not certain it's all getting translated to the pool like I'd expect. Any general or specific thoughts on this? I'll provide some specifics below: Times - These are just mid-workout times, nothing off the block yet. 50y - :37-:40 100y - 1:35 - 1:40 Dryland 75/80/90 Progression Incline Press - Max 130lbs Bulgarian Split Squats - weighted Pull-ups 5x5 weighted or Maximum Effort (depends on incline press progression) Face Pulls - 20lbs 90s plank 45s plank - sides 25x each: hip raises, leg lifts, flutter kicks, plank to pushup, some exercises I don't know the name of Pool Workout Average of 3400y, usually a warm-up of 300 (ea.) swim, kick w/ fins, paddles, and a drill Mixture of rest interval distances for main set. More kick Cool down Any feedback would be helpful, and I appreciate you all taking the time to look at my post!
