Working through fb fit 2- today was kick boxing cardio.... and oof. Daniel says “make sure you keep your feet moving!”

And uh. I do not. I just punch.😂😂

I do ok until I try and emulate whatever is being done with the feet. The punches I can get.....but the feet?

I can’t figure it out and I look... well. I look thankful I don’t do this on YouTube. 😂😂

Is there an FB video where they explain what to do with the feet? Or can someone take pity on me and share what you do?😂
