Raising Standards in Brand-Independent Rebound Fitness Education across the Globe
Rebound LAB was founded by Agnese Bluma (United Kingdom) and Tatjana Sperber (Germany) -
two experienced rebound professionals united by a shared vision to elevate rebound fitness education.
Bringing Together International Experience and Complementary Strengths,
they Lead Program Development, Instructor Training and Global Growth,
Building a Connected and Professional Rebound Community Across Borders.
Agnese Bluma
Founder & Lead Program Director (United Kingdom) -
- of Rebound LAB, an independent education platform dedicated to raising professional standards in rebound shoe fitness training across the UK and Globe.
With an athletic foundation rooted in competitive sport, including over a decade of basketball alongside athletics and martial arts, Agnese developed early discipline, resilience and a structured approach to performance. These principles now underpin the educational framework of Rebound LAB.
After relocating to Ireland in 2008 and later to the United Kingdom in 2013, Agnese expanded her professional pathway within the fitness industry. In 2019, she identified a significant gap within the rapidly growing rebound sector - the absence of structured, safety-led and brand-independent education.
Driven by this vision, she founded Rebound LAB to establish a progressive, systemised approach to rebound instructor training. Together with her co-founder, she co-designed and developed the Rebound LAB signature programmes - a comprehensive education pathway built on biomechanics, intelligent programming and long-term instructor development.
Under Agnese’s leadership, Rebound LAB has evolved from a national initiative into a growing European education network. She oversees program direction, quality assurance and strategic growth, ensuring consistency, integrity and innovation across all training delivery.
Recognised internationally within the rebound community as “Bluma,” she is respected not only for dynamic instruction, but for her commitment to professional structure, mentorship and sustainable industry development.
As a mother of four, Agnese brings both strength and perspective to her leadership, balancing family life with the continued growth of Rebound LAB across the UK and beyond.
Tatjana Sperber
Co-Founder & Co-Director (Germany) -
- of Rebound LAB, playing a central role in program development, instructor education and international expansion.
Born in Ukraine and based in Germany since 2008, Tatjana’s movement foundation was shaped through professional training in acrobatics and dance. These early disciplines cultivated exceptional body awareness, coordination and a strong understanding of biomechanics - principles that continue to inform her precise and technically structured teaching approach.
Alongside her movement background, Tatjana holds a university degree in Finance and Entrepreneurship with a focus on Marketing. Her business education and strategic mindset contribute to the structured educational systems and long-term development model implemented within Rebound LAB.
Since 2020, Tatjana has been dedicated to rebound fitness, inspiring people worldwide and educating instructors to deliver high-quality, safe, and effective training. Together with her co-founder, she co-designed and developed the Rebound LAB signature programs - a progressive training system built on innovation, precision, and a clear vision to elevate and transform the global rebound industry.
