Amazon's No.1 bestselling back massager is just $20, today only

Relieving sore muscles in your back, neck and shoulders is a must, but those spots can be hard to reach on your own. Well, heads up: Amazon is running a one-day sale on a mega-popular self-massager that's specially designed to hit those tricky spots. It's called the LiBa massager and, just for today, it's nearly 50% off.

The LiBa self-massager features a unique design to help you target muscles in your back, neck and shoulders without needing to shell out for a masseuse or call in a friend to help. The tool has different nodes and curves you can use to hit the right spot, depending on the area that needs relief.

A nice perk: This massager weighs less than a pound, so you don't have to worry about your arms getting tired while you use it. It also features a comfortable grip, making it easy to handle, even for longer periods of time.

The LiBa is even BPA-free and hypoallergenic, making an allergic reaction a non-issue. The whole tool is crafted from fiberglass-infused material for a strong massager that won't snap when you really get in there. And, while color probably isn't the first thing you look for when shopping for a massager, it's good to know that the LiBa comes in several shades, including teal, purple, black and navy.

An army of Amazon shoppers swear the LiBa has helped relieve their muscle soreness and pain. One five-star fan with chronic neck and shoulder pain shared this: "I go to massage therapy regularly but I can't seem to stop scrunching up my shoulders at my desk job when I'm working on the computer. This thing is incredible. You can put it on a knot and put as much pressure on it as you can possibly stand. I'm in love."

A fellow happy massager gave this device top marks for being easy to use. "My massage therapist recommended this to me," they said. "He gave me a few simple instructions, but my favorite part is that this came with step by step pictured instructions. Very easy for me to understand, operate and refer back to. I don't have to remember each technique because I can always refer back to the instructions."

Again, this deal is just for today. Don't miss this chance to treat aching muscles for just $21!

And while you're at it, here are a few more deals you can snag today only:

These feet booties soak your skin in luxury. The mask works to remove dead skin on your feet and heels to prevent cracking, peeling and flaking. All you have to do is soak your feet in warm water for 30 minutes, then slide your feet into the mask for 60 minutes. When you remove the treatment, your feet will look and feel brand new.

"I cannot say enough amazing things," one reviewer shared. "This foot peel worked exactly as it said it would. I am singing its praise. I would not do this before a major event because it will peel and continue for about a week or 2, but the outcome is amazing!!!!"

The handy tool helps to smooth and brighten skin. The brush not only helps improve the appearance of scars, but it also works to improve circulation, firm skin and reduce cellulite. You can also work in your favorite oils to add additional moisture and hydration.

"If you’re not dry brushing, you’re not living!" an impressed shopper exclaimed. "I never thought I’d be a proponent of something so goopy, but this thing is really effective. When I use it, I can see little puffs of dead skin cells coming off. Great stimulating feeling afterward, too. I don't know if it's draining my lymph nodes or what not, but it seems to be helping with my dry bumpy skin (KP)."

If you're hunting for a soft massager, add this one to your cart. The silicone nodes gently massage your skin to boost circulation and stimulate skin cells to produce more collagen — an essential component for youthful and firm skin.

The massager is a match for all, even those with skin conditions. "I have lymphedema/Lipedema and have done dry brushing for a few years. My PT told me about this product and I now use it for my therapy. I purchased one for my home care and love it! So easy to use, and it really moves the skin gently and is perfect for the care of my skin," a reviewer wrote.

If you have Amazon Prime, you’ll get free shipping, of course. Not yet a member? No problem. You can sign up for your free 30-day trial here. (And by the way, those without Prime still get free shipping on orders of $25 or more.)
