No pain no gain, could you wear a helmet?!
It’s a shame you don’t have access to smaller plates, for exercises like overhead press then come in very handy.
A couple of solutions though if you wanna try that again would be…
Elastic band the weight on to the middle of the bar, no swing to worry about then.
Depending on what kind of collars you have available, use multiple collars.
Or obviously the helmet!
