Racket elbow is over-extended to 141.2° at impact instead of maintaining a relaxed bend within the ideal 60-120° range.
Train this →Racket elbow angle reached 116.7 degrees at contact, nearly fully extending near the 120-degree upper limit for a backhand low serve.
Train this →Racket elbow angle reached 160.1 degrees at contact, leaving the arm nearly locked straight rather than maintaining a functional bend within the ideal 95-145 degree range.
Train this →Insufficient torso coil during backswing, showing only 14.8° of shoulder-vs-hip rotation compared to the recommended minimum of 20° for overhead clears.
Train this →Minimal trunk and shoulder-hip rotation measured at only 0.9 degrees during execution.
Train this →Govind achieved only 4.8° of shoulder-vs-hip rotation prior to contact, showing almost no core coil.
Train this →Right elbow extended to 107.8° at contact instead of maintaining a compact ~90° angle during the low backhand serve.
Train this →Excessive right knee flexion down to 81.9° during the loading phase before contact.
Train this →Racket elbow was extended to 112.3 degrees at contact during the backhand low serve.
Train this →Standing too upright during the backhand low serve with a high 149.4° knee angle.
Train this →Lack of trunk rotation during the drive stroke, showing only 0.7° of shoulder-vs-hip rotation compared to the recommended minimum of 15°.
Train this →Minimal shoulder-vs-hip rotation of only 1.7 degrees at contact, far below the recommended 15 degrees minimum coil for a drive.
Train this →Govind stayed too upright during the stroke, recording a deepest knee bend of only 16.2°.
Train this →Shoulder-versus-hip rotation reached only 6.1° at contact (ideal is ≥20°), indicating a flat, square stance with almost no upper-body coiling.
Train this →Limited upper body coiling prior to stroke execution, achieving only 8.4° of shoulder-vs-hip rotation at impact compared to the target 20°+.
Train this →Left knee bend reaches 66.5°, dropping the lower body excessively low.
Train this →Minimal upper body rotation during shot setup, achieving only 4.5° of shoulder-vs-hip rotation.
Train this →Minimal torso and hip coiling during the overhead swing, generating only 5° of shoulder-vs-hip rotation.
Train this →Your shoulder-vs-hip rotation reached only 6.7 degrees prior to impact, showing almost no trunk coiling during the stroke preparation.
Train this →Excessive torso lean of 24.5° from vertical during serve contact (ideal range is 0-15°).
Train this →Minimal shoulder-vs-hip rotation of 0.1 degree at contact, failing to generate core rotation power.
Train this →Racket elbow was extended to 153° at contact, exceeding the recommended 60-120° range for a serve.
Train this →Minimal shoulder-vs-hip rotation of only 2.7° during the swing compared to the ideal minimum of 15°.
Train this →Minimal trunk rotation during preparation and hit, showing a shoulder-vs-hip rotation of only 3.9° (ideal ≥ 20°).
Train this →Played the drive with almost zero trunk rotation, registering only 1" shoulder-vs-hip rotation.
Train this →Negligible shoulder-vs-hip rotation of only 3.8° (ideal ≥20°) during the backswing and stroke.
Train this →Minimal body coiling during preparation, showing only 4.5° of shoulder-vs-hip rotation.
Train this →Minimal trunk coil before impact, registering a shoulder-vs-hip rotation of only 1.6 degrees.
Train this →Extremely minimal trunk and shoulder-vs-hip rotation measured at only 1.9°.
Train this →Only achieved 6.8° of shoulder-vs-hip rotation during preparation alongside an excessive torso lean of 39.8°.
Train this →Minimal body coil during the overhead stroke, achieving only 8.1° of shoulder-vs-hip rotation compared to the recommended 20°+.
Train this →Minimal shoulder-vs-hip rotation at contact, measured at only 2 deg compared to the recommended 15 deg minimum.
Train this →Shallow right knee bend of 122.7 degrees on the forward step rather than loading deeply into the lunge.
Train this →Racket elbow was severely collapsed at 38.8 degrees at contact instead of maintaining a extended angle between 95 and 145 degrees.
Train this →Racket elbow angle was 44.3° at contact, far below the ideal 95-145° range for a flat drive.
Train this →Racket elbow angle was bent at 72.7° at contact instead of full overhead extension (150-178°).
Train this →Your shoulder-vs-hip rotation measured only 1.6° at contact (ideal is ≥25°), resulting in an uncoiled, flat-chested swing.
Train this →Shoulder-vs-hip rotation was measured at only 0.4 degree during the stroke setup, showing virtually no core rotation or shoulder turn.
Train this →Deepest knee bend was only 39.3° during setup and impact, keeping the player too upright.
Train this →Minimal trunk rotation during preparation, recording only 4.1° of shoulder-vs-hip rotation (ideal is ≥20°).
Train this →Shoulder-vs-hip rotation is only 5 degrees at impact, leaving the upper body square to the net rather than coiling side-on.
Train this →Extremely minimal torso and shoulder-vs-hip rotation of only 3.5° during the swing setup.
Train this →Minimal body coiling with a shoulder-vs-hip rotation of only 0.8° prior to impact.
Train this →Excessive torso lean of 50.1° from vertical at contact (ideal for drives is 0-25°).
Train this →Extremely low body coiling prior to stroke execution, reaching only 1.7° of shoulder-vs-hip rotation.
Train this →Excessive torso lean of 42.6° from vertical combined with minimal shoulder-hip rotation of only 2.7° at contact.
