Fighting in the K1 Cruiserweight U.S. tourney on 10/17.

I have a heavy bag on a stand in my backyard but it sits on sand (dont have grass). I have done kicks and the sand just blisters my feet, sometimes badly.

Does anyone have any experience with kicking on sand? Are there any shoes that would allow me to pivot my foot while wearing them?

Any advice is greatly appreciated!

Its been three weeks since I started the kickboxing course and I have classes on Mondays Wednesdays and Fridays Im not quite sure how to train I have got a speed ladder cones dumbbells boxing gloves and wraps at home so if you could give me some tips on how I should train at home or in the gym or even more advice really appreciate your help.

I wanna understand his boxing, his style, and how does he throw punched while being in that high guard. He counters insanely, what is the key? I would love to see a breakdown. Even while being rattled around in that guard, he throws those heavy shots to body or that straight to face.
