OK so I'll be changing gyms now, mainly for financial reasons. New gym is the other uni in town's 28 million pound facility.
Pros: much more power racks and lifting platforms. Closer as well, and easier to get to.
Cons: no strongman equipment. That's about it, really. I live in the squat rack and my old gym only had the one - which was often used for other things as well since it had a lat pull down attachment - so I believe this is a much better choice.
