StrongHIIT is a dynamic advanced high intensity interval class with a focus on building strength and endurance utilizing the custom designed HIIT4 unit. Participants will learn to utilize the HIIT4 unit along with additional stations to focus on movements and exercises designed to improve strength, balance, lung efficiency and muscular endurance. 

Why Try StrongHIIT? 

StrongHIIT is like no other strength class you’ve experienced.  Working at a station with a team, you’ll have three rounds to pull, push, and lift stronger, with options to add weight, go deeper, or both each round.  With the team behind you, you’ll work harder and go further than you ever dreamed possible.  Finish it out with four Core and More exercises, and you’ll find your strong in no time flat.  

What Is StrongHIIT Like? 

StrongHIIT takes teamwork to the next level, with groups of four people working on the same exercise at the same station.  This adds a new level of camaraderie and community, which encourages everyone in the class to work harder every round at every station.  Teams will cycle through six strength stations, each featuring different strength-based equipment and exercises that will contribute to a full-body workout.   

Who is StrongHIIT Best For? 

StrongHIIT is the best introduction to the HIITZone for someone new to the gym: you have an instant fitness family, a full-body workout, and expert instruction from a coach who gives level options to make sure you’re challenged and successful. Not only that, these level options ensure that experienced HIITZone afficionados can rock their workout for their hardest challenge! 

Is StrongHIIT a Good Workout? 

StrongHIIT is an incredible workout for anyone seeking to use gym equipment found on the fitness floor in a team environment.  By taking up the challenge to find deeper range of motion and adding more resistance or more reps every round, you’ll find your strongest self in no time!

How Difficult is StrongHIIT? 

5/10. The exercises in StrongHIIT are tough, but the instructor’s level options and the cheering of your teammates will make the time fly while you get incredibly strong. By the time you hit Core and More, you’ll be feeling powerfully shredded! 

How Long Is StrongHIIT? 

The schedule for StrongHIIT shows 45 minutes, but that timeframe includes setting up your team and introductions, demonstration of the stations and exercise options, the actual workout, and time to reset the HIITZone. The actual workout itself is an incredibly efficient 30 minutes, so prepare to work your hardest each round to get the best results!
