Nobody wants to talk about their underwear—for good reason. Because no one wants to hear about your underwear. But...there's one exception to that. When a pair of underwear or a garment is so breathable, comfortable, and perfect for working out, gear-heads perk up (even if they're self-termed as fitness fashionistas). 

That's the total trifecta that I want in my panties. (!)

I tried all the best brands of underwear for active women—Under Armour, Moving Comfort, Nike, Knix Wear, and Thinx Period Panties—and I did AMRAPs, EMOMs, several-mile runs in the summer and more to find the top three underwear for women who workout, to keep you high and dry, even if it's that time of the month.

Stepping into the Reebok CrossFit box where the Fittest Woman on Earth Katrin Davidsdottir and other powerhouse CrossFit athletes have come to train is something special. To get to watch them train up close, workout with them yourself, talk to them, and pick the brains of their coaches is another. Take a look at the crazy workouts they take on to condition themselves for one of the toughest fitness challenges that exists right now: the Reebok CrossFit Games, coming up July 19-24. 

Let's take a look at the nation's heartbeat of the CrossFit community, with many of the athletes and employees at Reebok sporting the latest , and much improved, Reebok CrossFit sneaker: the CrossFit Nano 6.0 (the newest generation to older Reebok CrossFit shoes).

It's hard to stay motivated to train sometimes... unless you've got the right gear and the right JAMS! I love working out, running, cycling, etc. to good music, but when it comes to Tabata training (intervals of 20 seconds on and 10 seconds off), things can get little tricky. Try Up and Overs or bust out some Deadlifts while the weights are clinking on the floor and you're trying to hear the interval timer, or worse, to check your watch. 

HOW DO YOU STAY FIT WHEN TRAVELING? If you don't, and opt out instead, maybe it's time you changed that. Break a sweat while on break!

Running, going hiking, or renting a bike are all brilliant ways to whip away those extra calories you may be taking in on vacation. And however you like to crush your healthy living goals while on the road, here are six more awesome ways to hit that fitness target, with or without equipment.

To build a stronger, tighter core that helps you perform better as an athlete, or to start seeing your six pack abs you need to cut the crunches from your workout session—right away. That isolation abs exercise won't get you results like compound movements will. Why? Because the core, which is a wider group of muscles including the mid and lower back, abdominals, and even hips and shoulders, is meant to execute functional movements. And if you instead only work limited-range-of-motion exercises or don't train your core at all, it'll never be as strong, lean, or useful as it could be.

Cyclists, for example, need strong cores to power up the watts. Runners, same thing. The core muscles want to assist in dynamic movements and in maintaining static tasks like keeping a stable trunk so you don't wobble back and forth on the bike. So the more you train your core with functional moves, like thrusters, planks, and lunges, the more tuned in (and ripped) your core will become.
