With it being Friday, we've naturally got the weekend on our brains, and today we're looking to Jessica Biel on how to walk our pups in style. The actress ditched the usual dog-walking gear (we're looking at you, sweats) and instead was chic and sporty in an AllSaints striped sweatshirt ($110) over a AllSaints striped tank dress ($68). For comfort, she added a pair of Nike Dunk Sky Hi sneakers, and for extra edge, a black leather jacket. Although skirts and sneakers aren't the most obvious pairing, that's precisely what we love so much about Jessica's latest outfit — she tried the unexpected and it worked. So follow her lead by shopping similar pieces below.

Give yourself an extra lift this Summer in a pair of cool wedge sneakers from hot designers like Isabel Marant, Nike, Ash, and Chloé. These slick sporty kicks supply just the right amount of height without having to worry about sore feet the day after — in other words, the perfect fashion pairing.

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!
