Amazon Prime Day (AKA one of the biggest sales of the year) is right around the corner, and like every savvy shopper, I've already started strategizing on how to get the best deals possible with the least amount of stress. One of my favorite tactics? Shopping for my favorite products early.

While it may seem counterintuitive to start filling your cart before the official sale begins, so many must-haves from brands like Fitbit, Asics, Alo Yoga, Braun, and Spanx are already discounted. Best of all, these under-the-radar savings include most sizes and colors, so you don't have to sweat about the item you've been eyeing selling out. Below are 10 deals I'm shopping ASAP:

Fitbit's newest iteration of the Charge Fitness Tracker has everything I — a runner, hiker, and often lost walker — could ever need. In addition to GPS tracking, accurate step counts, sleep monitoring, and even the ability to count breaths per minute, this lightweight watch gives me the tools to regulate my stress levels with an electrodermal activity sensor that scans the body's physical reactions. Plus, this device includes a feature that tracks activity levels and helps wearers make informed decisions about their next workouts and recoveries. 

A-listers like Jennifer Garner, Hailey Bieber, Jennifer Lopez, and more are constantly wearing Alo Yoga, and with good reason. The brand's trendy, comfortable styles you can actually work out in have put it on the map. Take these high-waisted tights, for instance: Made from ultra-soft airbrush fabric, these cropped leggings keep you cool and secure with moisture-proof material and a seamless design.

While I love soft and comfy bras for lounging and running errands, high-impact bras that truly stop boob jiggle are a must when I work out. This stabilizing top from Under Armor features adjustable, crossed straps and a hook-and-eye closure that keep your breasts firmly in place and relieve weight from the bust area.

If you've ever considered splurging on a pricey hair removal tool, this gentle epilator will convince you that $100 (or in this case, less) is all you need to achieve a smooth, bump-free shave. Cordless and waterproof, this little tool removes hair more effectively than wax and delivers results that last up to four weeks.

With more than 12,000 perfect ratings on Amazon, this "miracle in a bottle," as one shopper described it, has won over so many people looking to revitalize their thinning hair. In fact, it's the retailer's best-selling hair regrowth shampoo, and for good reason: Another reviewer swears their hair is "twice as thick" after just one month of use. Both the included shampoo and conditioner are formulated with biotin, plus hydrolyzed keratin and spirulina extract to boost density and shine.

I convinced myself to buy a pair of these ultra-cushy slides while writing a story about them, and have seriously worn them every day since their arrival. In addition to giving my feet a soft landing with every step, they relieve soreness from my knees after running. While my durable purple slippers have held up so well through daily wear, I can't resist getting a second pair (and TBH, maybe third) while they're on sale.

I'm usually a fan of thin, grippy mats, but since getting more into cardio, my achy joints crave something cushy but slip-proof. At a quarter inch thick, this high-density yoga mat checks all the boxes by absorbing impact and supporting the spine while you're lying down. Plus, it features traction grooves on both sides to keep you upright through your practice.

After years of running, swimming, and jumping around during intense HIIT workouts, my knees are very sensitive, which is why I love cushy, joint protective sneakers like the Asics Gel-Venture 8. In addition to a supportive knit outer, these feature gel padding that absorbs shock with each step.

I rave about this K-beauty toner to friends, family, and strangers alike. Even in the midst of summer when my skin is oily and pores look enormous, a splash of this quick-absorbing formula instantly blurs, plumps, and gives my skin a healthy glow.

If I had to choose between my entire closet of clothes and these booty-lifting pants, it'd be a genuinely hard decision. The flared version of the trousers Oprah once called "ultra-flattering," they not only boast a sleek, trendy silhouette, but also maximum comfort for long days at the office. And the best part? They really do make my butt look great.
