The SISSFiT Method

How it works

Improve Your Race Times

The “secret” to getting faster and fitter is speedwork to improve turnover and inclines to build strength. This is exactly what our treadmill and outdoor run workouts do for you.

Lose Weight And Build Lean Muscle

Our HIIT workouts are the most efficient use of your time because you will burn calories while building lean muscle. These short bouts of intense energy followed by recovery spike and lower your heart rate, allowing you to burn fat during and after.

Get Fitter And Stronger

The combination of resistance training that targets every muscle group, HIIT cardio (of your choice), and endurance cardio keeps you continuously progressing and maximizing your caloric burn because the diverse variety keeps your body guessing without adapting and plateauing.

Support And Motivation

When you join the challenge, you become a FiTSISSter for life! We'll support, motivate, and uplift you to reach your goals.

"It ended up being one of the biggest transformations I have ever seen (and it really is only 30 minutes per day)! I have noticeably lost "cushion" around my stomach and have increased muscle tone and leanness over my entire body. I have never been a runner, especially on the treadmill, but the SISSFiT coached workouts are invaluable. They make the most of my 30 minutes and are great for any level of fitness. Lauren and Kelly's tips on running form were easy to understand and implement to stop heel striking. The strength workouts are fast and effective. Do yourself a favor and trust their methods and workouts, and give it a try. "


"The hardest part was wrapping my mind around only spending 30 min. per workout. I was used to running/walking up to 10 miles per day and only seeing minimal results, but the amount of time spent exercising was killing me. The 26-28 min. HIIT programs has transformed my body. I cannot say enough positive words to express my gratitude and positive changes that I have seen within my body and mind. Thank you, thank you, thank you!!!"


"I PR’ed a half marathon with 1.37, knocking 19 minutes off my time by SISSFiT workouts and a couple long runs! And 3rd in my age group! 🤗 Thank you Lauren Collins and Kelly Collins for such amazing workouts and empowering me where I was able to set a goal and achieve it with fun short workouts! You two are amazing!!"

"Overall, thank you thank you thank you for creating SISSFit and making workouts accessible (regardless of travel), challenging, and results-oriented. Also, thank you for pushing me to speeds and inclines I never thought possible (and never tried before)--you asked me to trust your system, and it really has delivered. I had no idea what I was capable of :)"
