I changed my mind over the stuff a few times but in the end, I figured I'd try and keep the price reasonable and then I can buy more plates if I need to.
Squat and Dip Rack - Decision based on the fact my garage has a low ceiling and I've used squat stands at my university gym plenty of times (confident on dumping the weight etc.)
Bench - Standard flat bench, I very rarely ever did incline or decline so it shouldn't be an issue.
Oly Bar + Plates (185kg) - As I said, I'll buy/borrow plates accordingly if needing to load more on the bar. Seemed sufficient for the time being.
I'll have the flooring sorted for deadlifts etc so it should all come together nicely. Only slight problem is due to the ceiling issue mentioned previously, I'll probably have to go outside for military press (just power clean it first.)
Total price was £445 after money off etc.
