My name is Marvin Joseph, and I'm a certified personal trainer with more than eight years of experience. I currently offer online personal training services that focus on weight loss, muscle development, and core conditioning. You can access my services via Zoom or through a personal training platform.

​Some of my clients have had great success with the ketogenic and low-carb diets, but most achieved even better results with custom diet plans. Personally, I've had success managing my own weight with a vegan/vegetarian diet and am currently targeting 5% body fat with a pescatarian diet.

​With my knowledge, experience, and certifications, I will help you get into the best shape of your life. You'll start seeing noticeable results in as little as six weeks. All exercises come with detailed instructions and demos, but I can also demonstrate each one during a live-streaming session. Live sessions cost more, but all my online training plans include a weekly live-streaming progress report and mandatory exercise technique assessments at least four times a month.

​Choose me as your online virtual personal fitness trainer, and you will gain a lifetime of knowledge and insight that will contribute to your long-term weight loss goals. Otherwise I look forward to be at your service for as long as you'd like.

​I believe in a training philosophy built on discipline, realistic expectations, and natural remedies to improve your overall health for the long term. My holistic approach to weight loss treats your well-being with the same importance as the effort you invest in each session.

​This means we’ll create a meal plan that you can enjoy, with detailed input from you. It will even include fun recipes for cheat meals you can earn by meeting your weekly goals. Based on your health report and questionnaire, I'll also ensure all your nutritional needs are met before and after each workout.

​My goal is to make your workouts as creative as possible and to teach you as we go. This ensures that you'll gain the knowledge and skills to continue living a healthy, active lifestyle long after you’ve reached your fitness goals.

​In early 2025, I attended a two-month workshop at a reputable hotel in the Caribbean. This training allowed me to incorporate a variety of activities into my personal training sessions, including water aerobics, spin class, flexibility training, and Caribbean dance fit classes.

With over two decades of dedication to fitness, Marvin Joseph, the force behind M Star Fitness, has become a beacon of inspiration. Originally from St. Lucia, Marvin's early years were shaped by a passion for sports, but he later faced a challenging period of health complications that caused significant weight gain. Undeterred, he began a remarkable journey to reclaim his vitality. A pivotal moment came when he adopted a holistic, plant-based lifestyle to combat inflammation. Through this transformative approach, he not only healed but also discovered new strength, speeding up his recovery and burning considerable belly fat. Despite suffering from injuries like sciatica, scoliosis, and multiple pinched nerves, Marvin emerged stronger in just six months, able to perform advanced physical feats without pain.

​Today, Marvin, also known as M Star, astounds even seasoned athletes with his strength and exercise movements. His gravity-defying calisthenics, including upside-down pushups, are a testament to his indomitable spirit and a powerful example of what can be achieved through a natural, holistic approach. Through his M Star Fitness Club, Marvin provides a dynamic platform for people who want to be in the best shape of their lives in the simplest, most natural way possible. He stands as living proof that a plant-based diet, thoughtfully curated to include occasional meat, along with progressive exercise, can be the most effective and cost-efficient way to prevent disease and live a longer, more vibrant life. M Star Fitness is more than a personal triumph; it's an invitation to anyone who wants to forge their own path toward vitality and well-being.
