Your Best Life | Trying out the new X4 class at Junction Fitness There's a new fitness option for anyone looking to get in shape this summer. This week Leslie Draffin checks out Temple's Junction Fitness and their newest class. Author: Leslie Draffin Updated: 5:40 PM CDT July 14, 2021 TEMPLE, Texas — Junction Fitness is a relatively new gym off Avenue M in Temple. They opened with CrossFit about a year and a half ago. Then this spring they added X4, a high intensity interval training or HIIT class. "So, we wanted to bring X4 to the Temple community because we felt like there was a gap, you know, we felt like there were a lot of people that we were missing and quite honestly, our mission is to try and help as many people as possible," owner and trainer Aaron Castilleja said.
