William Liveman is the founder of BestRebounderTrampoline.com, a resource dedicated to making fitness fun, low-impact, and evidence-based through rebound training on mini trampolines. His commitment to rebounding began during a personal health crisis—after being diagnosed in 2015 with Diffuse Large B-Cell Lymphoma (DLBCL) Stage IV and Follicular Lymphoma, William used daily rebounder sessions to help maintain strength, mood, and resilience throughout treatment. That experience shaped the site’s mission: reliable guidance, verified reviews, and practical education so anyone can “bounce back” to better health. At Best Rebounder Trampoline, William leads a team of fitness writers, health professionals, and experienced rebounders who produce fact-checked reviews, comparisons, and tips for home users, seniors, and professionals. The editorial approach is simple: prioritize safety, biomechanics-informed technique, and lymphatic-friendly protocols, then translate that into clear buyer’s guides people can trust. William’s work bridges product testing, user education, and community building, helping readers choose safer rebounders, protect joints, and improve balance and cardio with minimal impact. He’s an advocate of progress over perfection and an active voice in the rebounder community—sharing practical routines, gear advice, and up-to-date deal alerts to make high-quality equipment more accessible.

I am Founder of Active & ageless where we specialise in health & fitness solutions for over 50s. I love what I do and run my business like my life. If it's not scaring me a little i'm not pushing hard enough. Now sometimes I want to be lazy and idle also, and I enjoy it when I do, but I am disciplined enough that it never lasts. I strive to train hard, to work hard and at times simply enjoy life and even rest hard (and this could be surfing 10 foot waves in Fiji or doing a 50km hike). With a background as an emergency nurse, Army medic, and oil and gas industry medic, I’ve spent my career in high-pressure roles. With Active & Ageless, I’m redefining fitness for over-50s—growing to multiple locations and partnering with aged care facilities in just five years. After multiple back surgeries and advice to ‘play it safe,’ I chose the opposite: running ultra-marathons, surfing big waves, boxing younger opponents, and building a business that inspires strength, resilience, and a life without limits.

My career in the fitness industry began in midlife. I took a professional pivot after 2 decades in sales and marketing, to pursue my passion for exercise and nutrition. In the past 15 years, I've added to my initial certification to become a NASM Certified Master Personal Trainer and a Precision Nutrition Level 2 Master Health Coach with a specialization in Sleep, Stress, and Recovery.

I became a Certified Menopause Health & Fitness Coach, educator, and course creator dedicated to empowering people through midlife transitions with evidence-based protocols and compassion.

Marc has over 20 years experience training: in a sports medicine/rehab setting, as a group exercise instructor, and as an independent personal trainer. In that time, he has worked with a diverse clientele with a wide variety of physical abilities, and has gained extensive knowledge of orthopedic injuries and their treatments. Along the way, he has developed an intuition for helping clients dial in complex exercises and accessing pesky muscles notorious for insubordination, earning him the nickname ‘The Glute Whisperer’. Additional experience includes weight training (Olympic lifting, power lifting, and otherwise), group exercise training, TRX, HIIT, and he has been running ski conditioning exercise groups for most of his career. My approach to training is founded on the ideas that workouts should be functional, straightforward, and efficient - think less ‘Instagram exercises’ involving various contraptions and weird equipment, and more functional, repeatable, and economical exercises that replicate your sport or activities; that they should be comprehensive - looking at the body as a whole, rather than focusing on specific parts or movements; that they should be educational - teaching the client to use his or her body correctly and efficiently in both sport and everyday activities; and lastly, that they should build confidence as well as strength, and that making a workout fun is as important as all else.

I'm the founder and head coach of Siwicki Fitness, an online fitness platform delivering live virtual workout classes to women across the United States. Before launching Siwicki Fitness in 2020, I was a top 1% globally ranked group fitness instructor for Equinox, teaching at their flagship locations in DC, Bethesda, and Tyson's Corner. Siwicki Fitness was built around a simple idea. Women don't need another perfect program. They need one that fits around the life they already have. What sets us apart is the live virtual format. Instructors see members on camera, call them by name, and give real-time feedback. Members range from their 20s to their 70s and average 27 sessions in 8 weeks. I also run The Bridal Bootcamp, a wedding fitness program helping brides prepare for their big day with confidence and strength rather than crash dieting. Personal note: I was diagnosed with Type 1 Diabetes at age 5 and have managed my health through fitness ever since, including playing football at Dartmouth College. I'm available to comment on managing chronic conditions through exercise, virtual fitness, women's fitness across life stages, wedding fitness prep, and the realities of online coaching versus in-person training.
