助かるダイエットのプランクだけ番のアプリ

私好きなアプリがなかったんですけどこのアプリが大好きになっております。ホントみんなまじおすすめ絶対使った方がいいよみんな今まで聞いてくれてありがとう

音が出ない

サウンドをオンにしても、マナーモードを解除していても音が出ません。また、プランク終了とともに広告が流れるようになったのでとても不愉快です。

can’t read privacy policy or anything, it’s all in Chinese and you can’t use the app until you consent

通知ONで忘れずできるのはとてもいい

もっと秒数を実用的な数字にして欲しい
約3日で30秒増えたところで休憩無しでできる人は少ないし自分が出来る秒数でスケジュールを組み長く続けられるように出来ればいいなと思いました

プランク

やり始めて3年になると思うのですが、健康や体型維持だけでなく、気持ちが上向きになる、仕事にミスがなくなる、など脳にも効いている気がします。
とにかく、若い時からやっておけばよかったと思うし、これからもずっと続けます。今はほぼ毎日120秒です。
