I would think that excludes teeing up.
I always though the woods and 4iron would take very little divot as compared to wedges and high irons so it almost seems it should be the other way around?
For health reasons?
I know of one person who has been teaching for a long time who told me that he got arthritis in his hand or wrist, and he believes it to be from hitting off of mats for several years. I have no idea if that is accurate or not.
I hit off mats with all clubs all the time.
Maybe he had a reason for telling you that but I surely can't think of a good one.
Maybe he thought you only needed to practice short irons before you moved on to longer clubs.
Not much but that's all I've got.
I know of a couple of ranges where only irons are allowed because the range is too short, but that's about it.
BTW I got in trouble at one of those ranges for hitting a 5W (before I knew the rule). Funny thing was that a guy next to me was hitting a long iron that was going farther than my 5W and they didn't say a word to him.
I'll do that occasionally too. But it's gotta be a real bad chunk to hurt ... such that were you on grass, you would likely not even make it through. On mats it bounces, but at least it keeps moving. :)
Yeah has to be some really odd swing that would likely hurt on grass too. I don't see pain mentioned regarding mats as much as people think they are too easy to hit off of. What I like about mats is a consistent area to stand and the perfect lie. Makes working easy without needing to move around. Set up your camera, rods, whatever and get to work. I am mostly looking at ball flight, seeing where it starts and ends. Not too worried about how comfortable it is, typically not taking full speed swings anyway.
