I just came along this post and had to take some screenshots and that question for you guys... What is this?

Here is today’s little circuit for you guys. Circuit (1–3 rounds): • Squats x15 • Push-ups x12 • Plank x20 sec Rest: 30–60 sec Shorten plank to 10–15 sec if needed Did you finish all rounds? Be honest. Remember: you can’t water fake plants and expect them to grow.
