BIG3に集中したい人のための、シンプルな記録アプリです。 スクワット、ベンチプレス、デッドリフト。 この3種目を軸に、無駄なく記録できます。 セットごとの重量と回数をすばやく入力でき、 推定1RM・筋肥大レンジ・ボリュームも自動で算出。 1repで過去最高を超えると、MAXとして自動登録されます。 その日のコンディションや鍛えた部位、メモも残せるので、 BIG3以外の補助トレーニングをした日もジム日として記録できます。 成長はカレンダーとグラフで振り返れます。 総合的なトレーニング管理アプリではありません。 あれこれ機能を詰め込まず、BIG3を中心にした記録に集中できる環境を目指しました。 BIG3を本気で伸ばしたい方に使ってもらえたら嬉しいです。
