Typhoon Just a mat. I don’t understand why anyone would buy something that thick. It’s like it should be an insert for a mat
Very likely hitting off mats hurts his hands or elbows so he wants the extra cushion. He just hasn't considered what the extra height is doing to his swing, or doesn't think it matters. Years ago the only place near me never replaced their mats, they were thread bare and placed right on the cement. They would beat the Hell out of your joints. I thought about doing something like this guy is doing .
