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.

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.

Dr. Shiv Goel, MD is a board-certified physician and the founder of Prime Vitality Care, a physician-led functional medicine and wellness clinic based in San Antonio, Texas, with telehealth services available to patients in all 50 states. Dr. Goel trained in internal medicine and functional and integrative medicine, and has spent his career building a practice model that treats the root causes of poor health rather than managing symptoms in isolation. His clinical philosophy is grounded in the understanding that hormones, metabolism, inflammation, gut health, and mental well-being are deeply interconnected systems — and that lasting health improvements require addressing all of them together. Prime Vitality Care specializes in physician-supervised GLP-1 medical weight loss programs using semaglutide and tirzepatide, bioidentical hormone replacement therapy (BHRT) for women, testosterone replacement therapy (TRT) for men, peptide therapy including Sermorelin, BPC-157, and PT-141, and comprehensive functional medicine consultations for patients with chronic fatigue, gut dysfunction, autoimmune concerns, and metabolic disease. Dr. Goel is a sought-after expert on the clinical application of GLP-1 therapies, the role of hormonal imbalance in weight resistance, and the future of physician-led telehealth medicine. He speaks regularly to the gap between what conventional medicine offers patients with metabolic dysfunction and what a root-cause, functional approach can deliver when the right diagnostics and time are applied. Through Prime Vitality Care's HIPAA-compliant telehealth platform, Dr. Goel brings the same standard of clinical depth and personalization to patients nationwide that San Antonio patients have relied on in person — with lab coordination through local Quest Diagnostics or CPL sites and all prescriptions compounded and shipped directly to patients.

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.
