I still have the bruises from sparring with a coach last Friday!
It was a two-hour sparring session (obviously most people don’t go and spar for two hours, rather if you attend during those two hours then you can spar) and most people do so in the first hour (the gym closes after this 2hr session. A lot of people don't stay until closing time), however I can’t usually make it until the second-hour, which meant I (little sparring experience, 72kg) ended up doing one round with a guy who’d been there a while (98kg, looked a bit tired but wanted some more practice). We had a good round but had to stop as his leg cramped up...which left me and the coach in the gym.
Eight rounds later I was soaked in sweat, bruises growing, and grinning from ear to ear. Great fun and very worthwhile: while the coach didn’t verbally point out weaknesses (he’s Japanese, I’m English, we’re in Japan and he didn’t seem to know how much Japanese I speak), over eight rounds I had them pointed out to me the hard way .
This week I attended some non-sparring sessions, talked with those coaches about the weaknesses I’d identified* and we worked on those via pads. It’s going to take a lot more practice, of course, to get rid of the bad habits which kept seeing me hit, but I wouldn’t have had them pointed out to me had I not been sparring with the coach.
So, I thoroughly appreciate being able to spar with coaches.
* After me throwing a right body kick, he would return it with a right low kick. I wasn’t fast enough resetting and getting my left shin up fast enough, and thus got a very bruised left thigh. Got to work on resetting and checking faster.
The other was getting hit with his left hook after I did a right body kick. So this week I worked with my (other) coach on not swinging the right arm down when I kicked, but rather swinging it kind of across their face, to block any punches (I remember Sylvie having a video on this. The coach of the Thai national team taught this if I remember correctly...?).
