Exercise mat recommendations please

[Shopaholic100]

I’m looking to buy an exercise mat to take to the gym, for LBT, pump and Pilates classes. What type of mat do I need? I’ve looked in TK maxx as recommended on other threads but there is so much choice I don’t know which to buy. Do I need a 5mm yoga mat or padded foam 10mm Reebok/Nike type one? Some people have complained that there mats have fallen to pieces when doing mountain climbers etc, so any recommendations/ones to avoid appreciated. I don’t really want spend more than £30.

Which one do you have and would you recommend it?

I've got a couple of cheap yoga mats that I bought in ASDA many years ago and they're still good.

Going thicker is more comfortable for lying on, but less stable if you do standing work on it.
Yoga mats tend to be more grippy for poses like down dog.

I'd browse around some websites and see what the reviews are. They're a fairly basic item.

Does your gym not supply mats for classes etc?
