My husband and I, with my sister-in-law and her husband, recently did the Camino in Spain. Over 13 days we walked 340 kilometers. So obviously it was long distances every day, and as can be expected, your feet and your legs hurt at the end of a day like that. And every day after showering and before going to bed, we would put on the Bada Bing Bada Body magnesium rub with menthol crystals. And the next morning, we couldn't believe that our feet were fresh and ready for the next leg of the journey. It became very apparent that it's really working. The one night when my sister-in-law didn't put it on her legs, and she had sore legs the whole night, and the next morning her legs were still feeling tired. So this product really works for exercising, for long walks, for runs, sore, hot feet. I cannot promote this product enough. And most of all is the fact that it's a natural product. It's not expensive. It doesn't feed big pharma. So I can really suggest to anybody who wants to use this product that it is worth it.
