Ah, the warmer weather we've been waiting for has finally arrived. Which means it's time to replace the arm exercise you were getting with the remote control (I think I'll miss you most of all, "Pretty Little Liars"), with actual arm exercises -- hand weights and all.

Thanks to the return of skin-baring trends like the crop top, the desire for killer abs is no longer dependent upon whether you're hitting the pool in a bikini or not. Yep, abs are back in a big way. Simone De La Rue, celebrity trainer (she works with stars like Anne Hathaway and Camila Alves McConaughey) and founder and creator of Body by Simone, is here to help us achieve the toned tummy of our dreams through her book Body by Simone: The 8-Week Total Body Makeover Plan.

Sometimes finding the motivation to work out on your own can be harder than the actual workout itself -- which is why many of us have come to rely on a fitness buddy to meet our fitness goals. But gym BFFs do so much more than motivate us to get our butt in gear -- they know us on a deep and personal level. Not only do they know our BMI, but they've heard all of our weird, grunt-y (should-only-be-reserved-for-the-bedroom) sounds we make when lifting weights.

Let's address the Ganesh (err, elephant) in the room. You wear yoga pants regularly. But you actually practice yoga...maybe...once or twice a month? For busy women everywhere -- no matter how much you love the calm feeling after an hour and a half of breathing, stretching, and focusing -- it's tough to squeeze in a yoga class as frequently as you'd like.

You know that little voice in your head that whispers annoying things like "you can't do it" and "just give up" when you're uncertain about accomplishing a goal?

Wish you had legs like Taylor Swift or Kendall Jenner? Or maybe just legs you'd feel confident showing off in shorts or dresses this summer? Yeah, us too. That's why we talked to Yumi Lee Mathews, fitness expert and co-owner of the Reebok Crossfit Lab in West Hollywood, to give us the leg workouts for women that actually work -- and work fast.

There's a reason why every celebrity in Hollywood is lacing up her boxing gloves -- and it has nothing to do with training for a role inside the ring. According to Jeff Hunter, the face of boxing apparel brand Everlast and a trainer at YG Studios, boxing is the single-most effective way to tone the entire body and torch massive amounts of fat in a hurry. According to Hunter you can burn anywhere between 500 to 700 calories in a single 20-minute boxing session (as long as you're giving it 100 percent, of course).

If you're like most of us, you probably find your morning motivation at the bottom of a coffee cup. While coffee is life (you didn't really think we'd make you give that up, did you?), it's not necessarily the only way to kick-start a productive day. In fact, all you really need is your body and a few yoga stretches to perk you up.

While scrolling through Instagram does, in fact, burn calories (holla), you probably won't find yourself coming out as ripped or toned as the fitness gurus you just spent two hours stalking. Luckily, all it takes is a visual reincarnation of our #fitnessgoals to make us run straight for the gym. Whether you want to lift weights, practice yoga or simply enjoy images of animals working out, these are the top fitness gurus you need to follow on Instagram right now for all your fitness motivation.

Wouldn't motivating yourself to exercise be a whole lot easier if you had your own personal cheerleaders to pump you up with inspirational fitness quotes? And wouldn't it be even more inspiring if those cheerleaders were the cutest baby animals you'd ever seen?

If you've ever stopped waving at someone only to have the back of your arm continue to jiggle, then you know that excess fat has an annoying tendency to reside in triceps.

We can come up with a thousand excuses for skipping the gym. It's cold outside. You can't find your shoes. Those grunt-y bodybuilders make finding your happy place completely impossible. Plain and simple, it's a hassle to get to the gym and you just don't feel like going. Still, that entire pizza you devoured last night while binge-watching Netflix isn't going to burn itself off.

It happens to the best of us: You finally manage to get your butt to the gym, work out like a boss ... and then spend the next three days waddling around the office, thanks to extremely sore muscles. When even sitting on a toilet feels like an Olympic-like feat, you need muscle relief -- fast. Here, the only guide you need to getting rid of your workout-induced muscle soreness, so you can walk like a normal person again.

You don't need a fancy gym membership or tons of expensive equipment to get in shape. Gorgeous celebrity-news correspondent and "Dancing with the Stars" alum Maria Menounos is proof. In her book, The Everygirl's Guide to Diet and Fitness, she gives tips and tricks for getting healthy that require minimal time and money -- just like she did. (That sizzling bikini body is the result of dropping 40 pounds.)

When it's snowing, raining or freezing outside, getting to the gym, frequenting your barre class or logging an evening run gets tricky. And by tricky, we mean next to impossible. Instead of letting your workouts (and those abs you worked so hard on all summer) suffer while you're stuck inside, it's time to get creative.

The gym should be a happy place. According to science, exercise creates feel-good hormones and helps you live longer. But those warm and fuzzy vibes quickly vanish when you encounter a superchatty treadmill neighbor, grunting weight-hog or another equally annoying fellow gym-goer.

It's 6 o'clock in the morning. Ungodly, unfamiliar 6 o'clock in the morning. I'm sitting in the backseat of my Uber ride -- a conspicuous Kelly green Scion -- sipping a papaya Vitamin Water and coasting toward Downtown Los Angeles. Eyewitness News plays on TV screens imbedded in the back of each headrest, a feature my driver tells me he added extra. He offers me Tic Tacs and tissues. I deny both. I am trying hard to focus on the horizon, to stay awake, to prepare myself.

For our ancestors, "work" was related to basic survival -- hunting for food, toiling away under a blazing sun or lugging water from a source miles away. Sitting, when it happened, was used as a way to recuperate from the tough physical labor required to survive. These days, it's hard to find a job that doesn't involve sitting in a chair and click-clacking away at a keyboard for eight hours a day. But instead of the cushy office chairs leaving us well-rested, our sedentary lifestyle is taking its toll. The truth of the matter is, it isn't just your imagination -- your desk job is slowly killing you.

Most of us have an arsenal of serums and creams to fight wrinkles -- so why aren't we taking the same all-in approach when it comes to tackling another major pitfall of aging: a slowing metabolism?

I'm a type-A kind of gal who needs to stay busy -- and productive -- all day long. Whether it's squeezing in a few sun salutations while my morning coffee is brewing, or late-night cleaning and nail-painting while catching up on the latest "Mad Men" episode, I'm a crammer.
