Well i'm going to go for it and get it done, you only live once!
What would you recommend I put in it? My mum said I should get plastic balls on the barbell because a metal one will chip my teeth, if I play with it (which I know I will, I won't deny it, I fidget)
Or a flat plate? Or something... or just a regular silver ball?
(I'm not really looking for answers like "silver ball will look the best", i'm talking more like, health-wise)
