The secret to getting faster and fitter

What’s the secret to getting faster and fitter? Speedwork to improve turnover and inclines to build strength. This is exactly what our 4-week treadmill guide ACCELERATE will do for you.

We know, we know, you “hate running on a treadmill” and dread cardio. We did too! That was until we learned how to properly incorporate intervals... All of a sudden, the time flew by, our speed and mileage improved, and we got into amazing shape.

Our ACCELERATE plan includes three 30 minute workouts a week that focus on strength, endurance, and speed to improve your turnover, build lean muscle, and burn fat (300-500 calories per workout!).

"After completing my 1st round of Accelerate, I ran a 5k today @ 25:47 down from 27:32! So glad I found your program!!!! "

Katie C

"After each workout I was drenched in sweat and felt a deep sense of accomplishment [...] I felt my legs get slimmer and more toned as the weeks went on. After the first few workouts I had sore abs from the speed and inclines. 10/10 recommend their treadmill guide!"

Jeannette M

"In just four short weeks I have noticed a huge improvement in my overall running. Thanks to the speed intervals, I’ve discovered gears I didn’t even know I had and I’ve beat my 1 mile and 5k pace records significantly. Thanks SISSFiT!"

Laura N

"So excited!!! After just a couple weeks of the SISSFiT treadmill training I got my 5k time down to 23:30... haven’t seen a number like that in years!"
