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 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.
