The Booty Builder® Training Zone

The Booty Builder® Training Zone

Glute workouts have become one of the fitness industry’s hottest trends in the past few years. The reason is simple – as education and consumer awareness of the benefits of glute exercises has increased, so has the demand for booty workout areas and programming.

  • Glutes are one of the biggest muscle groups in the human body and therefore key to athletic performance, improving speed and explosiveness.
  • Glute training helps reduce risk of injuries and protects the lower back
  • Strong glutes help maintain proper alignment of the pelvis and spine, improving posture and reducing back pain
  • Developing this large muscle group will result in increased metabolic rate, leading to more calories burnt throughout the day
  • Most importantly, strong glutes aid every day functional activities and improve overall general health and well-being.

Each new piece in the Booty Builder® Training Zone has been created and designed to cater for specific consumer demand. We’ve listened to what the market wants – and delivered to its needs!

What Our Clients Say

Dealing with Tracy at React Fitness has been a seamless process from beginning to end – With plenty of communication and in-depth product knowledge we had full confidence when purchasing both the Booty Builder and Styku. Tracy spent time with our team to explain the software and we felt she was willing to go above and beyond to make sure we were comfortable with what we were installing in our club. We would have no hesitation with dealing with Tracy again in the future.

“The booty builder has been a great addition to our state-of-the-art facility. We had great feedback from our members once we purchased this and we even had new members signing up to our gym after seeing the booty builder on our Feel Fit Gym social media. React fitness delivered the booty builder on time as agreed. Great service, we would definitely recommend others to work with them!”
