Weight / Fat Loss

Start Shredding Pounds

Losing weight is a challenging process for anyone. You don’t want to follow aggressive diets and calorie restrictions or look for “magic supplements” that provides a short lived, temporary weight loss. Weight loss is a journey in which you have to change your daily habits. A healthy diet along with exercise go hand-in-hand in maintaining a healthy weight, improving body composition, and increasing energy. Our Boot Camp and StrikeFit programs are designed to burn hundreds of calories in a short amount of time, build strong and lean muscle, and lose excess fat.

If you’re struggling with weight and looking for a personal trainer, Mariusz will design a specific program which helps you to transform your body and improve your lifestyle.

Mariusz is a strong believer that a healthy and balanced diet is the most important part of the weight loss process. He’ll provide you the nutritional guidance and answer any questions that you may have regarding diet, nutrition, and supplements.
