Nothing gets folks more excited than a new gadget, and today the world is all abuzz with news of Apple’s latest release: the Apple Watch Series 3 has officially arrived.

Available in two sizes, 38mm and 42mm, and gold aluminum (in addition to classic silver, space gray aluminum, stainless steel, or space black stainless steel), this new wrist bling makes major functional strides from previous versions. The most notable change is built-in cellular access that shares the same number as your iPhone, starting at $399. (There is also a version without cellular that starts at $329.) This is huge. No longer tethered to your phone, you can go off into the world (or maybe just for a run, bike ride, or errand) and leave your smartphone at home, but still be able to make calls, receive texts, use GPS, stream music through Apple Music (available later this fall), talk to Siri, and, yes, pay for that post-run cup of Starbucks. The extra convenience comes at a cost, of course—for cellular access, you’ll pay more in your current monthly cell phone bill (prices vary depending on provider).

To buy: Starting at $329; apple.com

Equally cool, Apple was able to add technology upgrades (hello, 70% faster dual-core processor, in-screen antenna, and eSIM card) into the Series 3 without noticeably altering its size. It's physically comparable to the Series 2, save for the extended back crystal, which is about as thick as two sheets of paper. Not bad. The only other visual cue that you're sporting the newer version is a red dot on the crown of the watch, which is meant to distinguish between the cellular and non-cellular versions.

Let’s talk battery life, always a big concern for consumers. The Series 3 is supposed to be able to keep on ticking all day long, and thanks to the bigger processor, it should run more efficiently too. Keep in mind, though, that this device is not intended to totally replace your smartphone (at least not yet)—it’s more for mixed-usage purposes. In other words, a hours-long gabfest with your bestie via your wrist could definitely drain the battery.

Also good: the new operating system, watchOS 4, which comes with the Series 3, is pretty cool. You’ll have access to a slew of new features, including an updated Heart Rate app (it alerts you to spikes in heart rate even when you're not working out), a new Siri watch face, upgraded Workout app with custom HIIT workout type, and more. It's also worth noting that it's possible to download the new watchOS 4 operating system on older models (I did so on my Series 2) and reap most of the upgrades.

So should you buy the Apple Watch Series 3? I just got my hands on one and I’ll be testing it for the next week. But so far, I've been impressed with how intuitive the Series 3 seems to be compared to previous versions. The upgrades to the Workout app also caught my eye (my favorite feature: when you start running, a little icon of a person runs on the screen with you). I even made my first watch-based call with a little help from Siri, and it was exciting to not have to rely on my phone.

There have been reports of issues with the cellular function on the Series 3 (some of the watches are allegedly connecting to unauthenticated wireless networks, and the company is investigating a fix). That said, if you're someone who wants to be able to go phone-free, this may be the wearable you’ve been waiting for. If that's not a major concern for you, perhaps consider the non-cellular version.

For all the runners out there, keep in mind that there's an Apple Watch Nike+ Series 3 version launching in October. So many choices, so little time.

Follow along once with us, then repeat it as many times as you want.

A leaner, more toned physique isn’t the only incentive for building stronger thighs. Strengthening your muscles in front (quadriceps), back (hamstrings) and in between (adductors) is key to walking and running with ease, and jumping and squatting with power. Rock solid thighs will also provide a solid foundation for movement in any plane — for everyday and athletic feats.

But if you’re tired of standard squats and lunges, stepping up to the barre can help give your lower half the TLC it needs. Becca Pace, lead trainer for Daily Burn’s Barre Harmony program, says, “Barre workouts allow the smaller muscle groups [like the inner thighs] to fire up and engage.” Barre’s signature lengthening and strengthening pulses and pliés target the thighs like no other. And we’re combining six of Pace’s favorites into one muscle-torching thigh workout. If your legs start to shake, that means your thighs are really working.

6 Barre Exercises for a 30-Minute Thigh Workout

Using a chair that’s about hip height, do 10-15 reps of each of the six moves below. Repeat for two to three rounds. “Higher reps of more intricate exercises tests muscle endurance and builds strength and flexibility without putting pressure on the joints,” Pace explains.

1. Second Position Plié with Relevé

For this classic barre move, Pace says when you’re bending your knees in plié, press the outer edge of your feet down and pull your knees back to prevent them from falling in.

How to: Stand behind a chair with your feet in second position (feet slightly wider than hips-width with your toes turned out at 45 degrees), hands resting lightly on top of the chair. Roll your shoulders back and tilt your pelvis forward so your hips are in a neutral position (a). Sit into a grand plié squat with your hips in line with your knees, and then lift your heels off the ground in relevé (b). Squeezing your glutes, bring your heels back down to the ground and do a demi-plié before standing back up (c). This is one rep.

2. Reverse Lunge to Passé Combo

This lunge combo tests your hip mobility and balance. “When you’re going to passé, press firmly on your front foot and push off the ball of the back foot to bring your toes to the inner knee of the front leg,” she says.

How to: Stand parallel to a chair on your right side with your feet in first position (heels together and toes turned out to 45 degrees) (a). Take a step back with your left foot and sink into a reverse lunge. Then, bring your left foot back to first position (b). With your left foot pointed, tap it to your left side and then come up to relevé on both feet. Lift your left knee bent out to the side, and with your left toes pointed, touch your right knee in a passé position (c). This is one rep. Do 10-15 reps before switching sides.

3. Curtsy Lunge Pulse

Be sure to evenly distribute weight in each foot when you’re in a curtsy lunge. “Aim both hips forward like headlights and wrap inner thighs toward one another, like magnets,” Pace says.

How to: Stand behind a chair with your feet hip-width apart, hands lightly resting on top of the chair (a). Step your left foot behind you to your right side and lower your body into a demi-plié (half-squat) (b). Lift your arms up overhead in third position and pulse your legs for 10-15 reps before switching sides (c).

4. Tuck in Demi-Plié with Relevé

Imagine leaning your back against a wall when you’re positioning your body for this move. Your back should remain in neutral throughout the entire movement. Pace says to pull your belly button up toward your ribs to activate your core.

How to: Stand behind a chair with your feet hip-width apart. Place a rolled up towel between your thighs, just above your knees, and squeeze them together tightly (a). Engaging your abs, tilt your pelvis slightly forward with your tailbone pointed down. Bring your heels up up to relevé (b). Squeezing your thighs and glutes, demi-plié up and down for 10-15 reps before lowering your feet back down to the ground (c).

5. Inner Thigh Lift

As you lift your bottom leg, be sure not to shift your hips forward or back, and keep your core activated as you lower it back down, Pace says.

How to: Lie on your right side on a mat with your left leg stacked over your right leg. Cross your left leg over your right, planting your left foot firmly on the floor on your side and lying your head down on your right arm (a). Keeping your right foot pointed, lift your right leg off the ground and then bring it back down. This is one rep. You should start to feel the burn in your right inner thigh (b). Do 10-15 reps before switching sides (c).

6. Rainbow

While this exercise is meant to work your thighs, your obliques will get some lovin’, too, in order to keep your hips square. “Try to avoid the hips lifting and dipping, but instead, continue to point them down,” Pace says.

How to: Get in a tabletop position with your hands right under your shoulders and knees under your hips. Bring your right leg out to the side with your knee straight (a). Keeping your hips square and engaging your abs, sweep your right leg up and over to the left side, so you create a rainbow with your leg. Bring your right leg back to the starting position. This is one rep (b). Do 10-15 reps and then switch sides.

Britney Spears is always documenting her sweat sessions on social media, but a workout is nothing without the perfect playlist.

The pop star, 35, shared a montage of an outdoor arm workout combined with some exercises on a yoga mat in the gym to Instagram on Sunday. The video was set to JAY-Z‘s song “BBC,” which features a reference to Spears’ famous “Britney, bitch” lyric.

“When this song came out, I lost my mind like a little kid!!!” the singer captioned the post. “I fangirled and cried!!”

Spears donned a pink sport bra and purple shorts that showed off her toned abs before sporting a grey top for her indoor workout.

Spears is a documented fitness fanatic  who gives fans a peek into her intense gym sessions – and showes off the results on Instagram. It’s not rare to see her breaking for selfies mid-split to doing an impressive handstand in only a bikini top when browsing her social media feed.

The singer even includes her boyfriend Sam Asghari in her active lifestyle, sharing photos of them hiking for his 23rd birthday and of her standing on his shoulders in the pool.

Spears previously said having her sons — Sean, 11, and Jayden, 10 — changed her approach to exercise.

 “After I had Jayden, it was real easy for me to get back in shape,” she told Women’s Health. “But five years later, I started noticing changes in my body. My hips are a bit wider because I’ve had kids. So it was crucial for me to be continuous with my exercise. Consistency is key.”

“Daily exercise is important for me both mentally and physically,” Spears added. “I don’t mind working out. Trainers keep you motivated, but I don’t have a problem being motivated.”

Thinking about running a 26.2? You've probably budgeted how much time you'll need to train. But you might be wondering just how much money a marathon will cost you. To help you plan for the big race, we've broken down the expenses—everything from entry fees and sneakers (you'll likely need two pairs) to recovery massages and Gu. Here's how the costs can stack up:

Entry fee

For most marathons, this ranges from $60 to $300. More prestigious and popular races (often in big cities) tend to have a higher entry fee. Sometimes you have the option to run on a charity team, in which case your entry fee is covered; but then you might have to fundraise anywhere from $2,000 to $5,000.

Qualifying costs

To run certain marathons, you need to quality. That might mean running a competitive time. Or it could mean completing a series of other races. Those qualifying events could run you from $60 to $300 each.

Travel

Many marathoners like to sign up for destination races, and make travel a part of the whole experience. A domestic flight or long drive and one-night hotel stay could cost between $200 and $600, and possibly more, of course, depending on where you go and when.

Shoes

These are a definite training necessity. Many runners use two pairs, one for the majority of their training, and a fresh pair (with about 20-30 miles on them) for race day. If you’re a bargain hunter, you may find great sneakers on sale for $60. But most pairs cost around $100. Two pairs might set you back $120 to $250. Many runners also need arch supports to avoid foot injuries, which could be an extra $25 to $60.

Training fuel

For all those long training runs, you might want to stock up on some portable snacks and good sources of electrolytes (think Gu, Gatorade, sport gummies, and bars). You can often buy these in bulk on Amazon. A 16-pack of Gu will run you about $21. And you might need three boxes to get through your training. Add in drinks and gummies, and you could spend up to $150 on fuel alone.

FlipBelt or arm-band phone holder

It’s nice to have somewhere to stash your essentials when you run. A FlipBelt, around $20, can hold your phone, lip balm, headphones, keys, and a Gu packet. You can also opt for an around-the-arm phone holder, which costs about $7. 

Training gear

If you already have plenty of workout clothes, you can skip this expense. But good running gear can do wonders for your training and comfort on long runs. If you’re training in the summer, you might mix and match three pairs of leggings, three pairs of shorts, three tank tops, three sports bras, and a running hat. All of this could cost $500 to $870, depending on what brands you pick. For winter training, a jacket, three long-sleeve tops, running gloves and a warm headband might cost about $250 to $350. Keep in mind, these rough prices are for technical, performance running gear. You can definitely train well and feel great in less expensive options.

Accessories

Think sport sunglasses, headbands, and hair clips. For all three, this could cost up to $150.

Socks

High-quality running socks are more expensive than you might think; and having thick, cushion-y, durable pairs is key for preventing blisters. Five pairs could cost $55 to $75.

Recovery tools

Training for a marathon is no walk in the park, and you’ll need to invest time and money in stretching and recovery just to make it to the starting line. A foam roller, lacrosse ball, and regular trips to the gas station for bags of ice (for chilly baths after long runs) will add up to about $100.

Sports massages

These might be a luxury for some, but other runners rely on massage to keep them healthy and moving. One massage could cost $100. One per month for four months of training would add up to $400.

Intermediate races

To test your progress as you train, you may sign up for other road races like 5ks, 10ks, and half marathons. These can help you focus on speed during training. The cost to enter these races may vary from $20 to $100.

Gym membership

Even if you’re regularly running outside, you may want a gym membership to run indoors on super chilly or rainy days, and for access to cross-training options like the elliptical and stationary bike, as well as strength-training machines and weights. Depending on the gym, a six-month membership could run you $60 to $900.

Hand-held water bottle or water bottle belt

Getting thirsty on a long run is zero fun, and if you don’t run in a city with accessible drinking fountains, you’ll probably want to purchase one of these water-carrying options. It'll set you back $15 to $30.

Headphones and jams

They can do wonders, keeping you pumped up and motivated. Basic earbuds cost about $15 and an in-ear wireless pair will be $50 to $130. If you buy new songs to build the ultimate playlist, factor those into your expenses too.

Sport watch

You’ll want one of these to keep track of your pace and distance. A basic sport watch goes for about $45, while a GPS tracker will be around $150.

Training plan or coach

Not every runner will want this, and you can find many training plans for free. But lots of people can benefit from having a coach and a personalized plan. Coaching services could set you back about $150 a month (so $600 for four months) and training plans are about $150 as well.

Body Glide or baby powder or anti-chafing spray

Lots of running equals lots of chaffing. To avoid the burn, you’ll want to invest in something like Body Glide, which is about $8 for a stick.

Obviously not every runner will need all of the gear and other options listed here. But if you shelled out for everything above, a marathon could cost you more than $5,000.

That feeling you'll get when you cross the finish line? Priceless.
