It's not a stair machine, I'm going to use this machine to sweat a lot
If I use it for 20 minutes, it feels like an hour
Don't think 20 minutes is easy 😂😂😂😂😂😂 If you get the chance, you should try to climb these stairs for 20 minutes straight ㅋㅋㅋㅋㅋ
Wait
I don't know if this is accurate, but does that mean this machine's level will rise by more than a hundred floors??
