忙しい日の隙間時間にぴったり

1回たった4分なので、忙しい朝や寝る前でもパッと取り組めます。サクヤちゃんがいるおかげで運動のモチベーションが保ちやすいです。
記録画面も見やすく、アップデートでさらに使いやすくなりました。日々のちょっとした運動習慣におすすめです。

手軽に運動習慣が身に付く

4分ってあるので、抵抗感が少ないです。
ジムに行く時間が無い、と良いわけはできます。
でも、家で4分も時間が無いとは自分は言えないので…(笑)

何をやったら良いか分からない人には、ゆるHIITやり続けてください。
これだけでも、1ヶ月毎日杯続けたら絶対変化を感じると思います。

僕は、最後に仕上げのプランク60秒を追加してます。
結構鍛えられた感がしますよー。

フレンド機能があるのも良いです。
良い意味での相互監視社会になりますを
