Sure, you’ve seen TODAY’s Jenna Wolfe breaking news stories with Lester Holt on the weekends from Studio 1A, but did you know that she’s also a personal trainer? Passionate about fitness despite her hectic schedule, she often does what's called a "pyramid workout" when she travels for work in order to keep in shape while she is on the road.

The Pyramid Workout does not use any equipment or weights, meaning that she (or you!) can do it at home, in a hotel room, or anywhere else.  You just have to be able to count!  It is a series of ten moves done for a certain number of reps. The first move (jumping jacks) is a hundred reps, then for each subsequent move the reps are decreased by 10, until the final one (kick-drops), is executed for only 10 reps. 

Jenna says that doing this once is the perfect warm-up before you go for a run or, done four times, can be a complete full-body workout for the day.

Her fellow TODAY journalist, Natalie Morales, was up for the challenge of learning Jenna’s workout routine. (Natalie herself is no newbie to workouts -- she’s a marathon runner!) The two go through each of the movements in an easy-to-follow way so that you, too, can learn the workout! 

See the video, above, to hop in the gym with these two sporty TODAY anchors.

My favorite workout partner is not my best friend, or my yoga instructor or my spin teacher. My favorite workout partner is music.

Music meets me at the gym everyday (and is never late).  Music gives me energy when I'm lagging. Music motivates me, inspires me, pushes me and stimulates me. A customized, unpredictable workout mix, with a good balance of high energy music, along with steady, sometimes slower-paced rhythms can turn a sluggish 30-minute routine into a 60-minute experience. In fact, a growing body of research lends scientific credence to music's motivational powers. 

I have 12 different workout mixes that I change every month to keep everything fresh. I use certain mixes for strength training, others for cardio, and others still for yoga and meditative exercises. Whatever music you respond to, just make sure it's customized before you get to the gym so as to avoid constantly switching songs and distracting you from your workout.

My favorite workout songs change all the time. This week's picks will undoubtedly be different than next week's, but I'll share mine with you if you share yours with me. 

1) "Wild Ones" by Flo Rida, featuring Sia

2) "Ageless Beauty" by Stars

3) "Tonight is the Night," by Outasight

TODAY anchor Jenna Wolfe isn't just a fitness buff who loves to work out (and has the muscles to show for it). She's also a personal trainer in her spare time. And now, she's your trainer — on Facebook, at least. Got a fitness query? Head over to our Facebook page and ask away.

Q: How can you work your shoulders without bulking up? — Connie Mell

A: This is the most common question I get regarding weight lifting. Women are worried about building big, bulky muscles and they shy away from the weights as a result.

The truth is quite the opposite. Lifting weights will both burn calories and speed up your metabolism. Women would have to lift extremely heavy weights to bulk up. What you want to do is lift heavy enough weights to max out at 10-12 repetitions. If your weights are too light, you won't see enough of a difference. The goal is to tone your body, not inflate it.

And always keep in mind that muscle weighs more than fat, so don't completely rely on the scale as you start to tone up that body. -- Jenna Wolfe

Jenna Wolfe grins at the camera as she races in a 2011 Girls on the Run 5K, an event that pairs adult "running buddies" with preteen girls who've spent weeks training to run the 3.1 miles. (Jenna's buddy isn't in this picture -- she's just ahead, crossing the finish line!)

There's a good chance I came up with the concept of Girls on the Run, a non-profit that helps preteens train for a 5K, when I was in fourth grade. I was a wide-eyed, incredibly energetic tomboy whose favorite "subject" in school was Phys Ed. (Don’t laugh.) I truly spent the majority of my brain cells trying to get my girlfriends to run around with me outside. Instead, I played with the boys by morning, skinned up my knees by day, and by night, listened to my mom ask me where her daughter was. 

I didn't really fit in. 

By my preteen years, I was still athletic, but at my school, it was uncool to run around, uncool to break a sweat, uncool to be athletic. I was laughed at by the other girls, stared at weirdly by the boys, and once again -- I felt different from everyone else. I didn't know where I belonged.

I never quite fit in as an athletic young girl growing up, but I’ve always been that way. I played sports in high school, as well as in college. I was a sportscaster on TV for 12 years before coming to TODAY. I’m also a personal trainer on the side. And like many athletic women, I just plowed my blind way through the world, feeling on my own as a young female jock.

So when I was first introduced to Girls on the Run, a youth development program that uses running to motivate, inspire and instill in preteen girls a sense of self-esteem, confidence and a healthy lifestyle, I warmly embraced this amazing group of women. They do such important work. They impart wisdom, guidance and soul-growth onto young girls who crave it growing up, no matter how socially settled they think they are.

I participated in a Girls on the Run 5K event with a group of girls last year. The way it works is that each adult partners up with a young runner. Of course, I came in looking for which adult was going to partner up with me, only to realize I was the adult. But once we got that settled, I met up with my little athlete and we were off. About a quarter mile from the finish line, she cramped up. So I pulled a “Jenna” and hinted that I'd be happy to carry her to the finish line. (I’m so competitive.) She looked me square in the eyes and said, "If I started this on my own, I'm going to finish it on my own.”

With that, she started walking (limping) to the finish line. And, wouldn't you know it, her friends, who could have easily run past her, all walked by her side to the very end. That’s when it clicked for me, and that’s when I committed to helping this organization out however and whenever I could.

I struggled growing up as an athletic girl. I shouldn't have had to.

Jenna continues to participate with Girls on the Run, most recently by speaking at a fundraising event. The 5K events are open to the community, and many are happening this week -- click here to find one near you!

TODAY recently asked me if I’d be interested in doing a story on strongman fitness. After all, I do have a crush on "strong" and I’m sort of obsessed with fitness. No brainer, right?

But up until that point, the only strongman I knew was from those ridiculously crazy competitions that would air at 3 a.m. on cable with big guys lifting bigger cars, dragging airplanes and turning over tires the size of Texas. My initial reaction was, thanks, but I'm not interested in muscles that outweigh my couch.

But I was curious. So we went to Carozza Fitness up in Stamford, Conn., to join a class.

My first reaction: Where were all the massive muscled men? All I saw were tractor-trailer tires, a few sledgehammers, large stone balls, and 15 women of all fitness levels eager to start a workout. Nobody looked like they could bench-press the building. Nobody looked like they could squat my car. And nobody had neck muscles that spanned an oceanfront. These were all fit women who had joined this class because they were bored of the fitness status quo. But could they handle this workout?

Does Al Roker know weather?

The class started with a 15-minute plyometric-based warm up: squats, burpies, jumping jacks -- a few fun moves to get the heart pumping and the strongman ego going. I sailed through the warm up fully confident I’d be fine with the workout.

Perhaps “confident” was too strong a word.

It began. One-minute intervals of the following exercises: 100-lb tire flips, sledgehammer swings, walking with a bar on your shoulders twice your body weight, 60-lb stone lifts, monkey bar swings, box jumps and kettle bell swings. You go from one station to the next with no rest until you get through the entire circuit. And then you do it again. (The word “again” quickly becomes your enemy.)

The constant movement makes for a killer cardio workout. The strongman moves mimic chores we do over the course of our day (lifting groceries, putting suitcases onto the plane, pushing boxes, carrying a kid). These women all swear by the class. They stick together and get through it as a team. They have all lost weight and built strength. But they have also fallen in love with working out again. You’re not on an elliptical for 40 minutes reading a magazine, or texting or talking or uphill walking. You are maximizing your efforts, depleting your tank. You walk away from a workout like this knowing you gave nothing shy of 100 percent. It was one of the hardest things I’ve ever done.

So how did I do? Let’s just say I came back a few days later (without cameras) to do the workout on my own again. As someone who has tried just about every routine, fitness craze and cardio class out there, this one made me feel the most empowered.

Have you tried a strongman workout? Would you? Let us know -- discuss this story on Facebook. 

On the Sunday edition of Weekend TODAY, Jenna Wolfe caught up with Dolly Parton about working with Queen Latifah in the new film 'Joyful Noise'; why she chose to take her talents to the silver screen for the first time in 20 years; and her response to jokes the movie makes about her fashion sense and plastic surgeries. When Jenna mentioned Dolly's "I am who I am, no qualms about it" attitude, Dolly joked, "Well, that's who I am. I'm not a natural beauty like people like you!" and went on to explain, "That's who I am. Even my personality's a little bit outrageous and over the top and I just feel more comfortable...I get up in the morning, I dress for all day, all night. My make-up is basically the same. I just enjoy."

She also dished about a star she hasn't worked with, but would love to... and who that is may surprise you! Check out the full video below.
