It's gradually getting hotter again.
I feel tired even when I'm not doing anything.
Summer is just around the corner.
If I don't get in shape, I won't be able to make it through the summer.
Getting in shape doesn't just mean working out—it includes eating well, too.
I need to eat food that gives me stamina.
I need to be careful.
また少しづつ暑くなってきた。

もう少しで夏だ。
体鍛えないと夏を乗り切れない。
鍛えるのは筋トレだけでなく食事も含む。
スタミナのつくものを食べなければならない。
気をつけよう。

around the corner.:すぐそこ(比喩)
includes:含む
