Busy Philipps Is Super "Into" This $11 Bath Product for Sore Muscles

If you follow Busy Philipps on social media, you already know she's the definition of #fitnessgoals, posting photos and videos of her gym sessions nearly every day on Instagram Stories.

"Exercising has really helped me so much, so I do make sure that I make time for that every morning, even if it means I have to move [a] meeting cause I have to go do my workout, you know?" Philipps told us in a previous interview. "It's non-negotiable for me and that is directly tied to my mental health. It's not even about [my weight], but just the way I feel. I know that if I make it to that workout every day, that's the one priority that I have set for myself."

ICYDK, Philipps is also a master of self-care. She recently told Allure that she treats herself to at least 20 minutes in the tub every single night. But if you think she relies on pricey bath products to get her in that zen space—think again. (

In a recent post on her Instagram Stories, Philipps shared that she's "into mustard baths" lately, alongside a pic of Dr. Singha's Mustard Bath Salts (Buy It, $11, amazon.com).

Formulated for achy joints, swollen feet, sore/strained muscles, and even back pain, Dr. Singha's Mustard Bath Salts are the perfect addition to your post-workout tub time.

Made from a blend of organic mustard powder and essential oils like wintergreen, eucalyptus, rosemary, and thyme, this bath soak offers a quick, relaxing way to ease sore muscles and facilitate recovery to help you crush it in the gym day after day.

If you've never heard of mustard baths, they're actually quite popular in Ayurvedic medicine, in which mustard seeds are believed to alleviate physical stress in the body by increasing circulation, rejuvenating the skin, and drawing out toxins. In products like Dr. Singha's cult-favorite soak, mustard powder is typically mixed with essential oils—so, don't worry, you won't give off any sort of weird mustard smell post-bath. (

Philipps isn't the only famous fitness enthusiast to rely on this affordable bath staple. Not only is the product Goop-approved (Gwyneth Paltrow once hailed it as an "OG" bath product that "really does the job"), but Olympic swimmer Natalie Coughlin has long relied on it for her own post-workout baths, calling it one of her "travel must-haves."

Dr. Singha's Mustard Bath Salts are also popular with Amazon reviewers, who have praised the soak for its ability to ease cold symptoms in addition to achy muscles. "Bought this for my family during the winter because we kept getting colds and love taking hot baths," wrote one reviewer. "This feels amaaaaazing to soak in! Really nice smell, comforting for sore muscles and cold sweats, and leaves you feeling strengthened somehow."

The same reviewer even said that their boyfriend "swears by" the product whenever he's coming down with a cold. "He feels like it 'sucks the sick out,'" shared the reviewer.

Whether your muscles are in dire need of some TLC in the tub, or you're hoping to stave off as many germs as you can heading into cold and flu season, you'll want to snag these budget-friendly bath salts, which range in price from less than $5 to $33 for a giant tub on Amazon.
