Anyone tried fight Klub?

[jjxxx]

There's a local exercise class called fight Klub that is on a few times a week, i looked into it and it's a franchise so lots of these classes around the Uk. Wondering if anyone here been to one of them. Looking at videos of it on YouTube it looks quite good, but I'm nervous to book onto it, so just wanted some other opinions on what the classes are really like.

I've done it but not as a regular thing

what I found was that it was quite hard on the wrists - no matter how much I adjusted my technique. I've had tendonitis in my wrist in the past and didn't want it coming back. That said, I was holding up punch pads for partner to punch as well - not sure if they do that any more?

as an aerobic workout I did find it very hard, but good and I have asthma - which is under control but still technically I'm asthmatic and it was okay but very hard.
