筋トレが好きです。 大会に出るためではなく、鍛えること自体が好きです。 とりあえずジムへ行き、空いている器具やその日の気分を見て、何をするか決める。 フリーウェイトが空いていなければマシンを使い、予定していた器具が使えなければ別の種目を選ぶ。 そんな自由なトレーニングを続ける中で、困ることがありました。 「あれ、この種目は前回何kgだったっけ」 「最後に胸を鍛えたのは、いつだったっけ」 前回の記録が分かれば、 「前回できたのだから、今回もこの重量から始めよう」 「胸は3日前にしているから、今日は脚にしよう」 と、その日のトレーニングを自分で判断できます。 SA Trainingは、開発者自身が日々のトレーニングで使うために作った記録アプリです。 あらかじめ細かなメニューを組むのではなく、部位と器具から、その場で種目を選ぶ。 トレーニング中は前回の重量と回数を確認しながら、今回の記録を残す。 筋トレに集中しながら、必要な情報だけをすぐに確認できることを大切にしています。 【主な機能】 ・部位、器具、種目から、その日のトレーニングを選択 ・種目ごとの前回重量、回数、実施日の確認 ・重量と回数のスムーズな入力 ・インターバルとトレーニング経過時間の表示 ・日ごと、セッションごとの履歴 ・種目別の履歴、セット表、ボリューム推移 ・最大使用重量とBIG3推定1RMの確認 ・トレーニング画像の作成と保存 ・CSV形式での記録の書き出し ・複数の記録者の切り替え 開発を進める中で、 「セットごとの入力をもっと楽にしたい」 「インターバルを確認したい」 「積み重ねた記録をデータとして残したい」 「トレーニング結果を格好よくシェアしたい」 「過去の記録をAIに見せて、一緒にトレーニングを考えたい」 という要望が、自分自身の中から次々に生まれました。 その一つひとつを、実際に使いながら形にしています。 記録はCSVとして書き出せます。 AIに読み込ませてトレーニングを振り返ったり、表計算ソフトで整理したり、別の環境へ記録を持っていったりできます。 記録を特定のアプリの中だけに閉じ込めたくない。 積み重ねたトレーニングのデータは、使う人自身のものだと考えているからです。 そして、トレーニング中は筋トレに集中してほしい。 料金のことを毎月気にしてほしくもありません。 SA Trainingは買い切りです。 サブスクリプションはありません。 開発者自身が使用者として、これからも実際のトレーニングで気づいたことを反映し、より快適なアプリへ改善していきます。 自分のために作り始めたアプリですが、同じように自由なトレーニングを楽しむ人や、友人たちにも使ってもらえたらうれしいです。
