*WITHOUT THIS TURNING INTO SPAM*
What are the best and/or worst products that you've used for exercise and what do they do? If you want to show a picture of the product that's cool, but please no link to retailers selling it.
I'd have to say it's one thing that I can not do without in the summer time. The runners here probably know about it but for those who don't, it looks like deodorant and prevents chaffing. This works as advertised. I wish I would have discovered it years ago, it would have saved me many painful days of having chaffed legs, etc. It's not greasy, or messy.
I can't think of anything that stands out at this time. If I think of something I'll edit this.
