High-intensity interval training is still enjoying a wave of popularity,
thanks to its ability to stimulate results in less time than other
formats. Help attendees stay focused, engaged, and motivated to meet their
fitness goals as you mix it up with HIIT the Highway. This class features
dedicated 40-second work efforts followed by 20-second recoveries. One
unique aspect of HIIT the Highway is that it uses athletic drills that
relate to running and power, for a nice combination that truly
exhausts energy reserves.

The open-road blocks focus on running-based
movements. These drills alternate with power-trip blocks that incorporate
plyometric exercises. Perform each drill twice, allowing participants to
learn the drill in the first round and then push to their maximum capacity
during the second round. This class is easy to coach and cue and simple to
understand, while still being challenging for the participant. Get ready
to blast through barriers, cover ground and push speed limits in your next

Injury Prevention Tips

  • HIIT isn’t for everyone. Make sure participants
    know they should push themselves to their own personal edge and can pace
    themselves as needed.

  • Be sure participants are spaced far enough apart
    to perform the different movements. If drills require extra space, do
    them as a group so that everyone moves uniformly.

  • Since this class requires no equipment, carefully check the studio floor to ensure it is
    completely free of equipment and there are no obstacles in the room.

  • Provide cues for all level options to ensure that everyone feels
    successful. Give low-impact options for all plyometric drills.
