Did we mention she ran 4.5 miles beforehand?

Are you starting to feel that New Year's buzz and looking for new ways to get inspired? Meghan McNab has you covered. The badass mom and fitness enthusiast will motivate you to crush your resolutions right off the bat and here's why.

Over the weekend, one of McNab's trainers, Shawn Booth (owner of BOOTHCAMP Gym in Nashville, who you may recognize from The Bachelorette), took to Instagram to share how she completed a killer workout challenge so hard that it was designed to be pretty much impossible.

"Our coaches created a workout with the intention that nobody would finish it. We made it insanely difficult and wanted to see who could get the furthest through it," Booth wrote on Instagram alongside a series of videos of McNab sweating it out. "The challenge included 1,875 reps of all different exercises." (Related: Fit Moms Share the Relatable and Realistic Ways They Make Time for Workouts)

While that sounds tough as it is, Booth revealed that in order to even start the challenge, you had to complete a "buy-in" of 50 burpees, 50 push-ups, 50 wall balls, and 1 mile on the bike. Then for the challenge itself: 25 slam balls, 50 burpees, 75 wall balls, 100 single-arm kettlebell deadlifts, 125 rope slams, 150 lunge jumps, 175 goblet squats, 200 skiers on a bench, 225 mountain climbers, 250 Russian twists, and 500 jump ropes-which you can watch her power through in Booth's post below.

About 50 people participated in the challenge, and McNab was the only one to make it to the end. "This badass mom KILLED it," Booth wrote. "She was the only one of about 50 people yesterday to get it done." (Related: This Mom Has a Message for People Who Shame Her for Working Out)

As the clock ticked down, McNab's husband and her 4-year-old daughter, Sloane, cheered from the sidelines. At one point, Sloane even got down and hugged her mom as she did some toe-touches with a kettlebell in hand, per Booth's Instagram Stories.

"For me, it was the greatest moment we've had at Booth Camp Gym," wrote Booth, before sharing that McNab had actually run 4.5 miles before crushing every single rep. If that doesn't inspire you-if not to try the challenge, then at least to get your butt to the gym this holiday season-then nothing will.
