このフォームキーパーを装着して投げるだけで、ボールに力が乗るリリースポイントが瞬時に身につきます。
また、ゴルフスイングでは手首のブレを抑え、驚くほど安定したスイング軌道を手に入れられます。
投球時、ヒジが肩より前に出る「ヒジ抜け」は、肩やヒジへの負担を増やす原因。
硬質プレートが手首を支え、投球・スイング両方でムダのない正しい腕の動きを体感できます。
「固定し過ぎないちょうど良いホールド感が良い」と利用者から好評です。
手首の角度を意図的に固定することで、投球の悪いクセや、ゴルフでのオーバースイングやフリップ（すくい打ち）といった動作を意識的に改善に導きます。
左右の腕関係なく使える2WAY設計。
野球のヒジ抜け矯正はもちろん、ゴルフではリード腕（左打ちなら右腕）の固定や、ボールが引っ掛かってしまう癖の改善にも役立つマルチトレーナーです。
長さ:約16cm（面ファスナーで調整可能なフリーサイズ設計）重量：約45g 素材：ナイロン、プレートは硬質素材を使用
