Horse paste is good against covid, horse electrolytes are good against hangovers, what else is the horse industry hiding? Oh yeah, apparently horse tranquilizers whip ass too.
I've read somewhere that horse mats made out of rubber are pretty good flooring for home gyms and cheaper than something marketed towards gym use.
If it can take the full weight of a horse standing on it with its small hoofs, then it should have no issues with any weight you might drop on them during lifting.
Speaking of animal shampoo, me and the wife rescued some pups and they had issues...
Too young for flea/tick shampoo, but we found a hippy organic shampoo that just smelled like the best of the fall season. Took care of the fleas/ticks, and we kept it around for general dog bathing for the smell. It was amazing, lol.
