Perpindahan Berat Badan
Also known as: weight transfer, front-to-back-to-front
Weight shift adalah perpindahan berat badan yang disengaja dari kaki belakang saat load ke kaki depan saat swing, menghasilkan momentum ke depan yang menambah tenaga saat kontak.
Weight shift yang tepat dimulai dengan berat badan di kaki belakang saat load, lalu berpindah ke kaki depan yang menguat saat pinggul berotasi melewati kontak. Bergeser terlalu dini (sebelum pitch turun) adalah lunge yang mematikan tenaga rotasional; tidak bergeser sama sekali menghasilkan swing yang didominasi lengan. Kaki depan harus mengunci kuat saat kontak — sisi depan yang collapse akan membocorkan energi. Dalam slow pitch, waktu bola melayang yang lebih panjang memberi pemukul kesempatan untuk menyempurnakan urutan ini melalui latihan yang disengaja.
Check your finish. This means if you can hold your finish position for three full seconds with nearly all weight on your lead leg and the trail foot balanced on its toe, your weight transfer is correct.
Train weight transfer with a drill. This means start with your feet together, then stride with your front foot and immediately swing. This means the forced stride makes the transfer sequential and physical rather than something to think about.
Example
Berat badan dimulai 60% di kaki belakang saat load, lalu 90% di kaki depan yang menguat saat kontak — tubuh pemukul seperti pegas yang tergulung dan melepaskan tenaganya ke arah bola.
How it shows up on video
From a front-on camera, weight transfer shows the trail heel lifting off the ground during the downswing as the majority of body mass moves toward the lead side. A reverse pivot shows opposite movement: the lead hip drifts backward while the trail foot stays grounded through the entire swing. The finish position is a reliable indicator. This means a hitter who cannot hold their finish with 90 percent of weight on the lead leg has not completed their weight transfer.
Common mistakes
- Reverse pivoting by loading the lead foot in the load phase rather than the trail foot. This puts weight on the wrong side going into the swing and destroys power
- Hanging back and failing to complete the transfer to the lead side through contact. This forces the hands to flip at the ball to compensate for the stalled lower body
- Sliding the entire body toward the pitcher instead of rotating around a stable lead leg, which moves the swing center off the ball
- Transferring weight too early by lunging toward the pitcher before the pitch arrives, arriving with all weight shifted and no stored energy left to rotate into the ball

- Pengumpulan Tenaga (Load)Load adalah pergeseran berat badan ke belakang dan pelintiran tangan yang menempatkan pemukul pada posisi siap dan tergulung sebelum memulai swing. Dalam slow pitch, load harus terjadi lebih awal dan dipertahankan selama bola dengan arc panjang itu turun.
- Rotasi PinggulHip rotation adalah putaran pinggul ke arah pitcher selama swing — sumber tunggal terbesar rotational power dalam pemukul slow-pitch.
- Mekanika Sisi BelakangBack-side mechanics mengacu pada bagaimana pinggul, lutut, dan kaki belakang (trail) 'menembak' selama swing — sisi 'mesin' yang mendorong tenaga rotasional dari tanah hingga ke barrel.
- Timing Langkah KakiStride timing adalah kapan kaki depan mendarat relatif terhadap posisi pitch dalam arc-nya. Terhadap arc slow-pitch, kaki depan sebaiknya mendarat lebih awal — dekat puncak — sementara tangan tetap di belakang, menciptakan pemisahan antara tubuh bagian bawah dan tubuh bagian atas yang menghasilkan tenaga.
