Best way to get rid of all my body hair?

My main purpose for this I’ve been getting more serious about doing a triathlon and I want to do my best.

I use to not care when I would swim,but I’m starting to feel it could give me a bit of an edge now that my attitude has been shifting from for fun to more competitive. Not that I will come in first or anything. Its just for me personally.

So whats the best way to go about this???

I’ve shaved/trimmed in “certain places” but not anywhere else really…Any help is appreciated.
