The perfect fitness formula.
X4 bridges the gap between HIIT and functional fitness for a more well-rounded workout.
X4 was intentionally created to provide a holistic fitness option in a supportive group atmosphere. Unlike many group fitness gyms, X4 gives a consistent variety of anaerobic and aerobic training so members get a more well-rounded workout and never get bored.
X⁴ started in Homewood, AL as a HIIT class that was offered at a gym called Nexus Fitness when owner Chris Wade realized there was no comprehensive fitness option for all fitness levels. After 3 years of continued growth at Nexus, X4 became its own brand and launched its first independent studio in Mountain Brook, AL.
