Founded by Brett and Greta Beck, Bellabooty operates under Believe Pursue LLC, a product and project development company dedicated to creating he brand blends strength training expertise, inventive design, and a mission to make fitness - especially glute development more accessible - whether someone has full gym access or not.
Founding Story
Bellabooty was born in Los Angeles out of a simple but powerful idea: make glute training, especially hip thrusts, accessible and pain-free for everyone. As experienced trainers and entrepreneurs, Brett and Greta Beck noticed two major problems in the fitness world:
Pain & frustration - Hip thrusts with barbells left people bruised, uncomfortable, and often frustrated with clunky setups.
Limited access - Many skipped training Glutes entirely because they didn’t have the right equipment or a full gym setup.
Determined to solve these challenges, they set out to design a solution that would both eliminate the pain and make glute training accessible to anyone, anywhere.
This led to the launch of Bellabooty, the flagship brand under Believe Pursue LLC - a product and project development company founded by Brett Beck. Believe Pursue focuses on innovative solutions for fitness and lifestyle, and Bellabooty became its first viral success story with the creation of the world’s first patented hip thrust belt.
Developed and tested in their private Venice Beach gym, the Bellabooty Belt went from concept to viral product with over 100,000 units sold, helping people build stronger glutes safely and comfortably - without needing a full gym setup.
Greta Beck began personal training in 2016 after becoming a mom in 2015, when she earned her prenatal and postnatal fitness certification. What started as a personal curiosity for movement grew into a career dedicated to helping people feel stronger, more mobile, and pain-free. At Bellabooty, Greta blends her expertise in glute training and functional movement with a mission to make strength training accessible and empowering for everyone.
