For the first time in Prime Day's history, Amazon is hosting two Prime Day-like events in the same year. The second sale — dubbed the Prime Early Access Sale— ends tonight (Oct. 12) and offers sitewide savings for Prime members on popular categories ranging from skin care and home goods to tech and small kitchen appliances. Since it's so close to the holiday season, Amazon is also introducing a Top 100 list featuring deals on some of the most popular (and gift-worthy) products, the retailer says.

Whether you work out at home and need equipment or want to revamp your gym wardrobe, Amazon is still offering notable discounts on Peloton, Fitbit, NodicTrack and more during the Prime Early Access Sale. To help you make the most of the fleeting shopping holiday, we compiled some of the best Prime Day fitness deals and sales live on Amazon, plus highlighted other notable deals from counter sales at other retailers.

Below, we’re sharing the best deals from the Prime Early Access Sale on fitness gear based on our previous coverage and reporting. To ensure the quality of each deal, we’re running deals through price trackers like CamelCamelCamel and Honey — each product is at its lowest price in at least three months.

This immersive indoor cycling bike has a 22-inch rotating screen, 24 levels of resistance and up to a 20 percent incline, plus a set of dumbbells. The bike comes with a 30-day iFit family membership, which allows you to access on-demand workouts and studio classes.

This folding treadmill made Select's guides to the best folding treadmills, the best affordable treadmills, the best treadmill alternatives to Peleton's option and, you guessed it, the best treadmills overall. It offers three manual incline settings, can go up to 10 mph, according to the brand, and has 12 preset programs that can be accessed via the LCD display.

This expert-recommended massage gun from Select-favorite brand Therabody has five built-in speed settings and comes with four differently shaped head attachments. It is 70% quieter than previous generations and has up to two hours of battery life on a single charge, according to Therabody. Using the Therabody app, you can integrate your wellness routine with Apple Health or Google Fit.

This ab roller, a Select favorite from our guide to the best equipment for a home gym under $20, targets and challenges the front side of your core. The set comes with a non-slip rubber wheel, stainless steel handle bar (that you can remove for easy storage) and foam knee pad to cushion your legs.

With this fitness tracker, you can log 20 exercise modes, like biking, swimming or walking and interpret health data like distance traveled, calories burned and more. By measuring your heart rate, the wearable tracks your fitness as well as the quality of your sleep. Plus, it comes with a one year trial of Fitbit Premium, the company's advanced health app.

This generation of the Fitbit fitness tracker includes a built-in Alexa voice assistant, so you can set timers and alarms and control your smart home devices right from your wrist. In addition to tracking your heart rate, steps count and calories burned, this watch also monitors key sleep metrics — like your time asleep, your heart rate and general restlessness — to give you a sleep score and gain personal insights. The battery life should last around six days, according to the brand.

At their lowest price ever, these adjustable dumbbells from Amazon include two, 3-pound barbells on which you can add a total of four 2.5-pound plates and four 5-pound plates made of black painted steel. The weighted plates slide on and off the barbell and are secured into place with threaded collars. The set comes with a plastic storage case for portability.

This expert-recommended pilates ring from Balanced Body features padded handles on the inside and outside of the ring for a comfortable grip. It comes in a regular 15-inch size as well as a mini 12-inch size.

A popular tool for resistance training, a heavy duty rope like this one from AmazonBasics can be used for undulation, pulling exercises or climbing exercises, says Amazon. It's constructed with a three-strand-thick, heavy-duty polyester material, which the brand says won't fray or splinter, even if used outdoors.

These indoor cycling shoes have cleats that clip into the Peloton or Peloton+ bikes, plus any other pedal that has Delta-compatible pedals, according to the brand. The shoes have breathable mesh uppers and come with the cleats included.

These ankle weights are designed with five removable sand inserts so you can adjust the total weight from 1 to 5 pounds per leg. They also have velcro straps so you can easily adjust it to comfortably fit your ankles.

This Smart Rower from NordicTrack comes with a 22-inch screen that can tilt or pivot to your preferred view as you exercise along to its custom classes, available through the iFit app $39/mo). The bike (which includes the first 30-days of your membership free) has automatic trainer control, which means the trainers increase your resistance automatically, says the brand. The price has gone up a little bit since the start of the fall Prime Day sale yesterday, but we've included it since it is still a noteworthy deal.

This smart jump rope has a built-in chip and sensors that precisely count each jump on an LCD display. You can choose from three skipping modes: free jump, time countdown and a numbers countdown. When you pair the rope with the RENPHO Fit app, you can analyze and track metrics like your skip time, total number of skips, calories burned and more. The jump rope has non-slip foam handles and is made of steel wiring and wrapped in PVC, so it's durable enough for indoor and outdoor use.

The scale records 13 different health metrics including body weight, BMI, body fat percentage, water percentage, muscle mass, skeletal mass and more. It's also bluetooth compatible and can pair with the free ABYON app, Apple Health, Google Fit and Fitbit apps so you can view your personal health data. The scale also auto-calibrates to allow you to track measurements for multiple people in your household.

This expert-recommended kettlebell is made of a single piece of cast iron for a more durable construction. It has a wide enough handle that the brand says should allow for a secure grip with one or two hands. The kettlebell comes in different weights — from 10 pounds to 70 pounds — and some come in sets.

If you’re an avid hunter, fisher or golfer, you may want a rangefinder like this one from Gogogo sport. It offers three modes: golf (which indicates the exact distance you should swing), scan (which can measure up to 650 yards in the distance) and speed (which can measure up to 300 kh/h when you're hunting), according to the brand.

This protein powder was a global bestseller during Prime Day this past July and is now available at its lowest price ever. Vital Proteins says its unflavored collagen powder supports hair, nail, bone and joint health and can be mixed into hot or cold liquids. It comes with a scooper to help you measure out your servings. It is available in a 9.33-ounce container or a 1.2-pound container.

These 40-inch-by-12-inch cooling towels are made of microfiber mesh and come in a pack of four, meaning you can share them, use multiple at once or save some for later use. The towels come individually packaged and stay cool for three hours, according to the brand.

At 71-inches long and 24-inches wide, this yoga mat can be comfortable for all shapes and sizes, says the brand. The mat is made of half-inch thick, moisture-resistant, high density foam that cushions the spine, hips and knees while doing any floor exercise, according to BalanceForm. It comes with a carrying strap.

Though these high-waisted shorts are made of a thicker nylon blend fabric, the brand says they're still breathable. They have four-way stretch for a supportive fit, and the fabric is designed to be moisture-wicking, according to Aurola.

These Neoprene knee sleeves are non-slip and provide extra knee support during high-impact exercise like powerlifting or interval training or just walking and running, according to the brand. The ergonomically designed compression sleeves (which are sold as a pair) help keep your knees in the right place to prevent injury.
