Another solution to keep your hands dry...

[ChessGuy]

Rub a bunch of milk of magnesia on your hands and let dry. They will not sweat the whole day.

For those sweaty feet, rub on your feet and let it dry before putting your socks on. No more sweaty feet or stinky shoes.

Good for any body part which sweats.

balls?

Any side effects?

[PressesPeople]

Generally, not being able to sweat is pretty bad for you.

[ChessGuy]

Then I suggest not covering your body with it.

It will also make your balls fall off.

LOL @ this thread. But also, a product called Liquid Grip is pretty good. It's basically the same as using chalk but comes in a little bottle that contains some quick drying stuff that ends up like chalk once it's dry. It's a lot less messy than chalk too. I think I only paid like $4 about a year ago. I don't use it often but once in a while when I deadlift.

There's already chalk. It's easy and cheap.
