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.

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.
