This is just my personal experience, but I've noticed that I generally seem to lift heavier on the odd days I pop 400mg of Ibuprofen beforehand. Now bearing in mind that I don't ever take the painkiller for this reason,- it's usually just to help me work through pip on leg day,- but I have to admit, there seems like there 'may' be a connection, and so I'm curious to ask on the boards....
...Has anyone else experienced this or a similar effect?
