Best Fitness Challenge Experts

My name is Archna Sharma, and I have been working in the fitness field for the last nine years. Fitness has always been a big part of my life, and I love helping people become healthier and more confident. In 2022, I started Fitness Fasto so I could share easy-to-follow workouts, simple nutrition tips, and practical fitness advice that anyone can use in their daily life. Today, I have a strong online community, including 90K+ followers on Instagram, active followers on Threads, and fitness content shared on Medium and Pinterest. My business is also listed on Google, and my website fitnessfasto.com is where I share my programs and fitness guidance. My goal is to make fitness simple, enjoyable, and possible for everyone—no matter their age or lifestyle.

Hi, I'm Stephanie. The Anti-Diet Weight Loss Coach. I help people lose weight and keep it off - without diets or drastic changes - so they can feel better in their body and do more of what they love.

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.

Wendy Cheung, Co-Founder, Fluid X Wendy Cheung is the visionary Co-Founder of Fluid X, a company at the forefront of dynamic fitness solutions and instability training. Her journey into this innovative field began during the challenging times of COVID-19 lockdowns. With gyms closed, Wendy initially turned to aqua bags, treating them as traditional weights. However, a deeper dive into their potential revealed a transformative insight: the true power wasn't in filling the bags to capacity, but in embracing the unpredictable, shifting nature of water. This "live weight" effect uniquely challenges the body, training smaller, often neglected stabilizing muscles, leading to greater overall strength, a significantly stronger core, and the ability to lift heavier with reduced injury risk. Driven by this discovery, Wendy immersed herself in extensive research and collaborated with coaches and trainers globally, refining methodologies and gathering critical insights into the nuances of fluid dynamics in fitness. This commitment to practical, science-backed application led to the development of Fluid X's accredited coaching courses, now approved by leading organizations such as NASM, AFAA, and ACE. Wendy's expertise lies in making functional strength accessible and effective. She champions aqua bag training as a versatile, indispensable tool for anyone looking to build true resilience, stay stronger, and be fully prepared for the demands of everyday life, ensuring optimal movement and well-being. Wendy is passionate about sharing insights into innovative training techniques, functional fitness, and empowering individuals and professionals to unlock their full potential through intelligent, adaptive movement.

Back when I was an 11 year old punk kid my dad would get me in the home gym. And on weekends kick me in to line In the gym and at local sports. He’d say you didn’t get up early to come here and give a half ass effort. Leave it all in the gym. Years later when I competed in Speed Skating, we applied the same principles: we left it all on the ice. When I was selected for Ninja Warrior, that was part of my nightly pre competition prayer. Asked for the strength to leave it all on the course. Whether I was skating at local competitions or on National TV. Leaving it all…. means you give every ounce of effort you can, to give the best performance you can give. Whatever it is you do, whatever job you have… at the end of the day, leave it all there. The road leading up to Ninja Warrior was the most physically grueling part of my career. Got it handed to me the whole time. But I’m grateful to go to bed satisfied I left it all on the course.

Angela Fuller is a 45-year-old mom of two, history-making Masters gymnast, American Ninja Warrior competitor, fitness instructor, and inspirational speaker based in Highlands Ranch, Colorado. She is Colorado’s oldest competitive gymnast and one of the most influential figures in the adult gymnastics movement. In 2025, Angela made gymnastics history by becoming the oldest athlete ever to complete the NAIGC National Gymnastics Omnithon, competing in all 14 events at a single meet across women’s, men’s, and trampoline & tumbling disciplines. She earned multiple national medals, including second place in the men’s all-around, while competing against athletes half her age. Her groundbreaking achievements have been covered by CBS News, FOX31, Denver7, the Associated Press, and earned her a two-page feature in Inside Gymnastics Magazine, making her both the first NAIGC gymnast and the oldest gymnast ever highlighted by the publication. Angela’s impact extends beyond competition. After returning to gymnastics following a 27-year break due to injury, a broken back, and years of chronic pain, she rebuilt her body without surgery and eliminated back pain through strength training and movement. She now teaches fitness classes, mentors adult athletes, and has helped triple the size of her local adult gymnastics program, contributing to record-breaking attendance at NAIGC Nationals. Angela is passionate about showing women that it’s never too late to rebuild, redefine limits, and chase bold dreams at any age.
