Skill & Clips Rating Observations

Posture

2 2.464, 9.179 Your head position looks good but your chest-hip connection needs to be stronger so that you rotate your chest and hips as a unit.
Breathing
3 3.429, 13.143 The actual breathing looks pretty good, but while you breathe your spine gets out of alignment, your hips drop and your legs splay apart - all of this slows you down.
Rotation
3 2.5, 3.286 Your core is not rotating as a unit. You are getting about enough rotation with your hips to each side, but your shoulders are not rotating with your hips - rather they seem to be twisting after your hips, which may be the result of entering and extending your hands too near to the surface.
Arms
2 Extension: 1.429 Good extension but the hands are too close to the surface. This angles your body uphill and means you will have to press down on the water for a longer time to get a catch. Try to extend your arms at shoulder depth.
Catch: 1.464 Your hand very close to the surface a full extension, so you have to press down on the water for a long time to get your catch. This is a breaking action. In addition you are pulling back on your elbow before you have your catch, and that shortens your pull.
Pull: 1.893 Your elbow is deep and your hand-forearm paddle is under your body - it will slip sideways and vertically as you complete your stroke.
Recovery: 11.607 Your recovery looks pretty good except that your right hand seems to cut in front of your head instead of driving straight ahead.
Kick
3 2-Beat: Not evaluated. If you will be doing longer than sprint distance triathlons you should develop a 2-beat kick.
6-Beat: 2.786 Kick is compact but the knees are bending on recovery. Rather than recover your foot towards the surface with your hamstrings, use your glutes. That will keep your leg straight and allow you to kick with a long lever (hips-to-toes) instead of a short one (shins- to-toes).

Recommendations

Priority
Recommendation
1
Arms - Extension. When your arm reaches full extension, it should be at shoulder depth instead of at the surface. At full extension you should be rotated onto your side (at least 45°), and a line from fingertips to toes should be parallel to the surface.
2
Arms - Catch & Pull. Separate the catch from the pull. Try to keep driving your elbow forward as you get your hand and forearm vertical in the water, beside your body. Then pull straight back.
3
Posture. Every time you leave the wall, think "neck tall, chin back, belly in" to lock your head, chest and hips together.
