Going out on a limb here: Serena Williams has dealt with her fair share of muscle soreness over the years. Anything she recommends for recovery is probably going to be worth buying in bulk, and she recently called out a bath soak she's been loving. In a recent Instagram Story, she said she uses Asutra Skin Rejuvenator Bath Salts (Buy It, $25, after training hard.

Williams posted a video explaining that she heard about the product through her sister, Venus. "Venus got me this. That's not true; I stole this from Venus and she lives by it." ICYMI, Venus has a collection with Asutra of body oils, creams, serums, and the like. (Related: The Amazon Holiday Gifts On Gabrielle Union's and Serena Williams' Wishlists)

After admitting to stealing the soak, Williams dumped the salt into her bath straight out of the container, saying: "I always overdo it when I'm sore because yours truly has been training." Her tub was already filled with bubbles and stocked with other relaxing goodies like Saje Brainstorm Diffuser Blend Collection (Buy It, $44, and various scented candles.

Whether or not you deal with soreness, if you're partial to natural beauty products with decipherable ingredient lists, you'll love the sound of Williams' bath salts. She went with the "skin rejuvenator" edition of the salts, which contains only dead sea salt, organic essential oils, aloe vera, and vitamin E. The goal is to improve your skin as you soak, according to the product description. Vitamin E and dead sea salts are both moisturizing, and aloe vera is soothing.

Beyond treating your skin, the product also has the potential to help ease muscle soreness. A warm—not hot—bath is one way to send your body into rest mode after a workout. "Warm baths provide moist heat, which is the most beneficial type of heat for muscle repair and recovery," Katrina Kneeskern, D.P.T., a physical therapist at LifeClinic Physical Therapy and Chiropractic in Plymouth, MN, previously told us. "Post-workout, this can enhance recovery."

Like Epsom salt, dead sea salt is rich in magnesium, which helps with inflammation and sore muscles. But if you want to maximize the magnesium and care less about skin benefits/aromatherapy, you can also consider Asutra Magnesium Flakes (Buy It, $14,, part of Venus' collection.

Based on customer reviews, Asutra Ultimate Relaxation Bath Salts are a hidden gem. Of 26 reviews on Asutra's website, 25 have a 5-star rating, and people are 100 percent sold. "After adding the bath salts, lighting some non-scented candles and grabbing my book I was ready to relax and 'rejuvenate,'" one person wrote. " The scent is amazing and after a few pages, I just put the book down and closed my eyes.. 30 minutes later the water was getting chilly and I was soft, silky and de-stressed. That does not happen very often.. I even had to use less of my moisturizer."

Another person wrote that the soak really eases soreness. "Last night after a pretty intense yoga session I filled the bathtub with water added some of these bath salts, lit some candles and had a divine soak!" they wrote. "The bathroom smelled wonderful and my sore muscles and skin felt great after." (Related: How to Make Your Bubble Bath the *Most* Relaxing)

If you don't have a sister to steal from, you can get these soothing bath salts on Amazon. They certainly sound worthwhile for anyone who's training hard, but we can *all* benefit from soft skin and relaxation.
