STRONG Nation™ Stop counting the reps. Start training to the beat. STRONG Nation™ combines body weight, muscle conditioning, cardio and plyometric training moves synced to original music that has been specifically designed to match every single move. Every squat, every lunge, every burpee is driven by the music, helping you make it to that last rep, and maybe even five more. In each class you'll burn calories while toning arms, legs, abs and glutes. Plyometric or explosive moves like high knees, burpees, and jumping jacks are interchanged with isometric moves like lunges, squats, and kickboxing. STRONG Nation™ instructors change up the music and moves frequently to make sure you’re always challenged to the max. The STRONG Nation™ class is a demanding lesson that works your entire body. It’s ideal for hitting your ultimate fitness goals — and then making new ones. What to bring Towel (obligated).
