Prime Day 2025 is here from Tuesday, July 8 to Friday, July 11, and Lifehacker is sharing the best sales based on product reviews, comparisons, and price-tracking tools. 

It’s the third day of Prime Day (sing that to the tune of the Twelve Days of Christmas), and I’m still finding new deals on fitness items. Read on for the best deals on bikes, treadmills, smartwatches, dumbbells, accessories, and more. I’ll be updating this list with deals throughout the day (and tomorrow!) so keep checking back.

The best Prime Day deals on fitness trackers

I’ll cover a bunch of smartwatches below, but first I wanted to call out these other trackers:


What do you think so far?

  • Oura Ring 4 in black or silver, $297 (normally $349). This week is the first time the Oura Ring 4 has ever gone on sale, and you can read my review of this ring here. It’s a solid improvement over the gen 3 ring

  • Oura Ring 4 in brushed silver or matte black, $339 (normally $399)

  • Oura Ring 4 in gold, $424 (normally $499)

  • Whoop 5.0 with 12 months of “One” membership, $169 (normally $199). This is the budget tier of membership, but it comes with the same hardware as the middle tier that most people have, so you could always upgrade later if you decide you like it.

  • RingConn gen 2 ring in silver or black, $209.30 (normally $299). I haven’t tried this tracker myself, but it’s a subscription-free alternative to the Oura ring.

  • Ultrahuman ring, $296 (normally $349). This is another subscription-free ring option, and all colors are the same price. I’ve been wearing this ring—expect a review soon—and I can say it’s a pretty solid app experience, although a very different vibe from Oura. Less zen, more biohack-y. If I were making the decision on price alone, Ultrahuman easily beats Oura.

The best Prime Day deals on cardio equipment

Rowers

  • Hydrow Pro rowing machine: $1,735 today, down from $2,195. This rower has a 22” HD screen that can deliver live and on-demand workouts with a $44/month subscription. The smaller Hydrow Wave is $1,453, down from $1,695.

  • Peloton Row: $2,964.99 today, normally $3,295.

Bikes

Treadmills

  • NordicTrack T Series treadmills: The 6.5S model is $664, down from $799. Other models in the T series line are on sale, too, at that same link.

  • NordicTrack Commercial treadmills: The Commercial 2540 is $2,499, down from $2,999. It can go as fast as 14 miles per hour, and increase to a 12% incline. What’s special about this one is it can also do a 3% decline, incredibly useful if you’re training for something that has a lot of downhill running that you need to get used to. This treadmill also folds into an upright position for space savings.

  • Proform Carbon treadmills:The Proform Carbon TL is $463.99, down from $599. It has a built-in fan and a space-saving design. 

The best Prime Day deals on smartwatches

Amazfit

  • Amazfit T-Rex 3: $199.99, normally $279.99. Amazfit’s offerings are budget-friendly but have been getting more and more impressive, and the T-Rex 3 is among the brand’s best. You can read a review here from my colleague Matthew Miller at ZDNet—he likes it.

  • Amazfit Active 2: $99.99, normally $129.99. This one punches above its weight as well. You’re telling me we get sapphire glass and onboard maps for 99 bucks? I’m impressed. (So was Matthew Miller—here’s his review.)

Fitbit

  • Fitbit Charge 6: $99.95 today (normally $159), a great price for a tracker that does the basics solidly. (See my review here.)

  • Fitbit Inspire 3: $74.95 (normally $99.95). This is Fitbit’s budget tracker, without its own GPS capabilities—it uses your connected phone’s GPS.

Garmin

  • Garmin Forerunner 955: $349.99 (originally $599.99). This is probably the best deal on a Garmin you’ll find today, as it’s the Forerunner with built-in maps and tons of advanced running features. This is an older model (predating the 965 and 970) but Garmins have serious longevity and it’s not going to feel “old” anytime soon. The one caveat is that it has a MIP screen, which is an older tech, but some people prefer it anyway.

  • Garmin Forerunner 255: $199.99 (originally $349.99). Same pros and cons as I mentioned with the 955. It’s an older model (since replaced with the 265 and 570) but every bit a great running watch that will serve you well for years to come. I’d recommend it over the Forerunner 165, a newer entry-level model that is also on sale, but only for $231.99 (down from $249.99). The 255 has more features, like dual-band GPS, compatibility with cycling power meters, and extra analytics like training status.

  • Garmin Epix Pro (gen 2) Sapphire: $609.99 (originally $1,099.99)

  • Garmin Venu 3 and 3S: $399.99, originally $449.99. The Venu 3 is Garmin’s smartwatchiest watch, with voice calling and ECG features. The 3S is the same thing but in a smaller size. If you like the Venu’s style but you’re looking for a more budget-friendly watch, try the Vivoactive 5 ($190.99, originally $299).

  • Garmin Instinct 2X Solar: $299.99, originally $449.99. This is another slightly older model (there is now an Instinct 3 series) but this is still an excellent price on an excellent watch. This one features solar charging, an LED flashlight, and multi-band GPS in a rugged build—great for hiking and other outdoorsy activities.

Apple

Google Pixel

  • Pixel Watch 3: $299.99, down from $399.99. This is the newest Pixel watch, which I reviewed here—it makes a fine fitness tracker in addition to being a great Android smartwatch.

  • Pixel Watch 2: $206.34, originally $249.99.

Samsung Galaxy

  • Galaxy Watch 7: $159.99 for the non-LTE version in the 40 mm size, down from $299.99. The big caveat here is that the Galaxy Watch 7 is no longer the newest! A Galaxy Watch 8 was announced today and will start shipping July 25.

The best Prime Day deals on workout headphones

  • Shokz OpenRun Pro 2: $124.95, down from $179.95. These are the best bone conduction headphones out there. Bone conduction means you can always hear what’s going on around you, and the connected ear hooks mean you’ll never lose them or get them separated. Make sure to check their size guide to know if you should order the mini or the regular size.

  • Shokz OpenRun: $89.95, down from $129.95. These have a little less battery life and the sound quality isn’t quite as good as the Pro, but they’re still a great pair of headphones. I have an older model of these headphones and they’re amazing for workouts.

  • Shokz OpenFit 2: $124.95, down from $179.95. These are a pair of individual earbuds that each have an ear hook.

  • Powerbeats Pro 2: $179.95, down from $249.99 I love these headphones for their secure ear hooks and the fact that they have both noise cancellation for busy gyms, and transparency mode for when you’re running outdoors. The advertised heart rate feature is unreliable, though. Here’s my review.

  • Beats Solo 4: $97.99, down from $199.99. These are on-ear bluetooth headphones, great for the gym. It’s hard to argue with 50 hours of battery life and 50% off.

The best Prime Day deals on adjustable dumbbells

  • Powerblock Pro 100: This 100-pound dumbbell (sold as a single) is $509.99, originally $599.99. 

  • CAP Adjustabells (10 to 55 pounds): $208.99 for a pair, down from $299. This is an entry-level set that goes up to 55 pounds each, and are sold by the pair. 

  • Lifepro adjustable dumbbells (5 to 25 pounds): $159.99 for a pair, down from $199.99. Lifepro also has a 90-pound single adjustable for $255.99, down from $319.99.

The best Prime Day deals on home gym equipment

  • Keppi adjustable bench: $195.96, originally $279.99. I have this bench in my own home gym and it’s great—super sturdy for barbell lifts and easily adjustable. 

  • Lat pulldown handle set: $96.79, down from $120.99. This is a set of five handles in different widths, from narrow neutral grips to ultra-wide grips.

  • Barbell and bumper plate set: $406.10 for a set that includes 370 pounds of weights. That’s $1.10 per pound, which is a steal for bumper plates.

The best Prime Day deals on fitness accessories

  • Adidas Defender 4.0 duffel bag: $27 for the medium size, down from $45. I tell you guys every year that this is my favorite gym bag, and it’s still true—my six-year-old Defender in size Small still holds everything perfectly and looks like it’s brand new.

  • Ativafit weighted vest: $53.19, down from $69.99. This vest is adjustable and can go from two pounds up to 22 pounds, which will cover most of your rucking needs.

  • Flipbelt running belt: $27.75, down from $37. This is one of my favorite running belts, and holds a ton of stuff.

  • Nathan men’s/unisex Pinnacle Race hydration vest: $97.60, down from $180.

  • Nathan women’s Pinnacle Breeze hydration vest: $103.99, down from $129.99.

  • Stanley IceFlow Tumbler: $26.25, down from $40, to keep your water cold on a hot day at the gym or trailhead. (I am a huge fan of packing an icy cold drink to enjoy when I come back to my car after a run.)

The best Prime Day deals on heart rate monitors

  • Coospo H6: $23.99 (was $29.99). This is my personal favorite chest strap, the one I’ve had for three years and it’s still going strong.

  • Coospo H8086: $26.26 (was $36.99). Similar to the H6, but is a newer model with an LED indicator light.

  • Polar H10: $76.19 (was $104.95). The classic, solid choice, with internal memory.

  • Polar Verity Sense: $84.95 (was $104.90). This is an armband monitor, with an optical sensor—not necessarily as accurate, but still better than a wrist sensor. If you find chest straps uncomfortable, an armband is the next best thing.

Looking for something else? Retailers like Walmart, Best Buy, and Home Depot have Prime Day competition sales that are especially useful if you don’t have Amazon Prime.

  • Walmart’s Prime Day competition sale begins at midnight on July 8 and will include deals up to 50% off. It’s an especially good option if you have Walmart+. 

  • Best Buy’s Prime Day competition sale, “Black Friday in July,” runs through Sunday, July 13 and has some of the best tech sales online. It’s an especially good option if you’re a My Best Buy “Plus” or “Total” member.

  • Home Depot extended its 4th of July sale through at least July 9, competing with some amazing deals of its own. It’s an especially good option if you’re looking for power tools, appliances, or outdoor equipment.
