Hard to see much from above and the video is shaky… also, it’s much easier to explain and describe this shit in person, but here goes…
Observations:
1- You are dropping your elbows at the start of your pull. You need to drop your fingertips, then begin the pull by rotating your forearm and hand down and keeping your elbow up - AND keeping your fingers pointing down. Imagine that you are reaching over a slightly submerged barrel, or climbing a submerged pole that has tiny steps on either side.
2- You seem to be initiating your stroke from the shoulder, whereas it should initiate from the hip, just like swinging a baseball bat or golf club. It’s the rotation or “hip drive” that gives you power.
3- Your hand should be vertical throughout the stroke. Yours is an extension of your arm and so points forward at the beginning and points back at the end. Your hand is only pressing directly against the water when your arm is pointed straight down (which it shouldn’t be).
When you start your stroke, the idea is to get your forearm vertical in the water, and then pull it straight back (remaining vertical) until the shoulder has rotated far enough that your elbow is near the bottom of your ribcage. Then use your triceps to extend the arm, pressing water towards your feet (vertical hand). This means extending your wrist at the end of the stroke. Just pretend that you put your hand on a vertical shelf or step, and imagine that you are pressing against that shelf. Your hand would remain vertical, wouldn’t it?
At the end of your stroke, if your wrist is flexed, you can’t bend your elbow to lift it out of the water. The result is a very wide recovery. If you press into the heel of your hand (pushing the water towards your feet) your wrist is extended and you can easily lift your elbow for a more efficient recovery.
4- On recovery, you seem to be letting your hand “lead.” Better to recover by focusing on your elbows. Throw your elbow up and forward and let your forearm and hand go limp, almost as if your hand was attached to your elbow by a piece of rope and you’re trying to toss it forward.
5- Hard to tell, but it looks like you are kicking UP with your left foot when your left arm is extending. This reduces the torque force (propulsive force) that should impart power to the stroke. As I said earlier, start the stroke by rotating the hips, or “driving” the hip (and leg and foot and shoulder) down.
5- When you breathe, you need to be cognizant of the path your arm is taking. First of all, delay the start of your stroke until you get your face back in the water. What I do to assist with this is to push my hand/rotate my shoulder outward so that as I turn to breathe, my front arm stays in front of or just outside of the line of my shoulder. You’re turning your body and letting that shoulder rotate under you and then the stroke swings across your body.
If you ever get to the SF Bay Area, look me up and I’ll make a first class swimmer out of you. First thing to do is to lose the baggy “drag” suit!! If you’re going to be a swimmer, dress like one. Jammers, tri shorts or bun-huggers. But only wear the bun-huggers if your ass is tight.
