Just show up and we'll coach you through your headphones to world-class DJ mixes and keep you motivated the entire time. Only 5, 30 min workouts per week, and you have the flexibility to combine them to make it 3, 4 or 5 days!

You will finish this challenge feeling more confident, stronger, fitter, and in a workout routine that you can maintain moving forward.

2 Audio Coached HIIT Runs Per Week (1 Treadmill, 1 Outdoor Run) and 1 Cardio of Your Choice. If you're new to our workouts, think Orangetheory Fitness and Barry's Bootcamp.

Hey all! We're your coaches and we are thrilled to be coaching you through this 6 week challenge.

We are both former Division 1 track and field athletes, trainers and sports models with a real life understanding of how to balance work, kids and life with the desire to stay fit, healthy and train like an athlete! Yes, we've both had demanding careers outside of being trainers! :)

We don't like to waste time, so if you're used to a lot of steady state high mileage, this challenge is going to mix things up for you but if you trust us and work hard we can nearly guarantee you'll reach your goals.

Over these next 6 weeks, we will be personally coaching each of your runs through your headphones. This is different from most apps and it gives us the ability to personalize your workout and push you throughout.  Each of the strength workouts throughout this challenge have been designed to build lean muscle and the strength you'll need to become a faster, stronger and more balanced runner.

We also have over 10,000 playlists to choose from within our app, meaning you'll have incredible options for every workout and mood.

If you need help finding something, just ask! We are accessible via email and the Facebook group to answer any questions.

We look forward to seeing you stronger, leaner and faster in 6 short weeks!

Stay Inspired, Stay Strong,

Lauren and Kelly
