Most of us already know that tracking your food intake is an important aspect of a weight-loss plan, but tracking overall daily health and fitness is also important, even if you don't want to drop pounds. That could be the reason why so many fitness trackers are available for you to choose from; the Nike Fuel Band, Larklife, Fitbit, and Jawbone Up, for example, are all popular fitness gadgets equipped with accelerometers and sensors to track you all day (and night) long. Here's why these trackers can be a good aid for anyone wanting to live healthier.

1. You can see your fitness holes: It's one thing to have a sense of how healthy you are, but it's another thing to see the numbers. Many fitness trackers can record your steps, calories burned, and sleep, so if you're not meeting your goals in one or more of those categories, you'll be able to see it in no time. Fitness trackers force you to be aware of your fitness shortcomings so you can modify habits as necessary.
2. You can track your progress: Investing in a fitness tracker forces you to think about what you'd like to get out of your workout routine. Many trackers allow you to add goals — like steps per day or calories burned — so you can keep tabs on whether or not you are progressing. It's nice to have numbers backing up just how much more fit and active you've been feeling and to use as a basis for future goals.
3. You can push yourself safely: Listening to your body is the best way to know your limits, but having extra help doesn't hurt. Many fitness trackers compile the data they collect from your daily habits to show you trends over time. That means that if you find that you're being too sedentary on your nonworkout days or that you aren't burning as many calories as you thought in yoga class, you'll be armed with the information you need to modify your workout routine or your daily activity habits.

We are pumped to share one of our favorite stories from Self here on POPSUGAR Fitness!

This is kind of awkward: Even though I'm an editor at SELF, I get self-conscious in group classes and thus don't want to attend even though I desperately want to reap the benefits. Basically my life changed in 2011 when Nike relaunched their Nike Training Club app and I was able to do all these cool strengthening, lengthening and toning moves from the comfort of my (albeit cramped) living room — or anywhere else in the world. And someone else agrees with me. Namely this really famous, epic tennis star.

SELF has already sung Nike Training Club's praises before; we've even dubbed it a "personal trainer in your pocket." Well we've fallen all over in love again, and we're about to break some big news to you guys: Serena Williams has JUST launched her Core Power workout on NTC that's available for download and we have the first look — not to mention a few wise words from Serena herself.

Designed to work the core and abdominal muscles, Serena showed us that Core Power uses a stability ball and resistance bands to increase overall core strength, which in turn helps to create a lean, strong body. And when I spoke to Serena about creating Core Power for Nike Training Club, she told me that "the drills featured in the Core Power workout are based on key exercises I do regularly to stay strong. Everything I do on court begins with strength from the core, so it's the perfect foundation for my training as a tennis player." Core Power is also great when tacked on to a great cardio workout — even a run — and also helps Serena target specific muscle groups she feels need extra work. (Although, look at her. Look at her abs. Watch her play! What needs extra work?) Serena let us peek behind the scenes at the filming of her Core Power routine and officially gives you her new Nike Training Club workout from start to finish. Warning: Your abs will be feelin' it later!

Read on for the workout.

While catching a flight out of LA with husband Justin Timberlake, Jessica Biel gave her new white Nike Dunk Sky Hi sneakers ($125) a sophisticated spin. How so? By pairing them with supersleek pieces, including a collarless gray coat and matching gray skinny J Brand jeans ($202). Jessica then completed her travel style with a creamy netted sweater, a black tote bag, and oversize sunglasses. Wedge sneakers have practically become a style staple, but what we love about Jessica's latest outfit is that she proved that sporty can indeed look polished — that is, with the right accoutrements. Next time you're heading out of town (or just taking a spin around the neighborhood), take a cue from Jessica's latest and try matching your sneakers with a more luxe-feeling coat and any other pieces that scream chic (think leather pants, silky blouses, and tweed jackets). To get her look, shop our editors' picks below — including Jessica's exact Nike sneakers.

Isabel Marant may have launched a sneaker-wedge revolution, but Nike is taking the pumped-up look to new heights with its limited release of the Dunk Sky Hi City Pack, priced at $225 each. Inspired by five stylish metropolises from around the world — including New York, Milan, and Tokyo — you get the classic old-school streetwear silhouette of a Dunk high-top with all the luxe details of each city's iconic "personality" attached.

The New York style, at far left, features a metallic reptilian-print upper with black pony-hair panels and a patent leather Swoosh logo — a tribute to the New Yorker's signature all-black getup. Meanwhile, the London style boasts vibrant red plaid and green patent leather; the Milan iteration pays homage to its leather-crafting and luggage-making heritage with a crocodile-embossed upper; the Paris style looks to its romantic urban roots with a pale tweed-and-leather combo; and the Tokyo reveals itself as a city (or in this case, a shoe) driven by high shine and an insatiable desire for high tech via gorgeous iridescent accents.

If you suffer from sliding around on a mat during Pilates or yoga or prefer not to be barefoot during a barre class, then Nike's Studio Wrap Pack ($110) may be your answer to this problem.

The Studio Wrap Pack consists of three parts: the wrap portion that fits around the foot and ribbons (both pictured above) and a pair of slip-on flats that can be worn with or without the other parts of the Studio Wrap system. While it was a little confusing at first to wrap the ribbon correctly, once I managed to put them on, the sock-like wrap portion was quite comfortable. The stretchy fabric and open design offered a full range of flexibility for my feet and ankles. The ribbons were designed to give support to both the ankle and arch of the foot, but I didn't necessarily feel like they did this in a particularly effective way. But they did spark a lot of questions from admirers, both at the gym and at the yoga studio.

As someone who loves to go barefoot whenever possible, I found the wraps to be a little cumbersome during the yoga and aerobic dance classes I tested them out in. The wraps certainly provided traction when it came to floor choreography off the mat, but they moved around my feet during the more active parts of a mat workout.

While some yoga newbies swear by socks with grips, I worry that they won't learn about building up the foot strength that comes naturally with a well-designed yoga practice. When it came to dance class, I had a full range of motion and was able to move across the floor without any worry. But since the wraps didn't offer a great deal of cushion for the soles of my feet, they just felt a little unnecessary the whole time. My favorite part of the pack might just be the elegant studio flats; these simple, cozy ballet slippers held up on the streets during my city commute, and they were comfortable enough to run errands in after class.

I appreciate that the Nike Studio Wraps offer an open, breathable design; even with the extra coverage and support, your toes are exposed and easily able to connect with the mat. The socks aren't supportive enough for a class that calls for traditional sneakers or running shoes, but as for the "better-than-barefoot" and "flattering foot" experience they promise, the Nike Studio Wraps deliver.
