Discover the secret to training 50% less and getting 10 times more with KettleFit’s Unique Style of training. You literally get all your fitness needs met in every session via adopting the “Whole System Approach” which saves you time and maximises results. This whole system approach powerfully taps into a new evidence based science that has been little understood and overlooked for over 500 years in western medicine until recently. Moving from training the body as a bunch of separated parts in isolation (outdated systems) to training the body as one whole integrated system. Isolation training (Isolated Strength Training) versus integration training (Full Body Strength Training) KettleFit has created its very own system of training called “Kettlebell Centered Training” It places the most advanced all round athletic training tool on the planet at the center of every workout. The focus is on training the whole system at once combining over 13 years of Kettlebell training experience mixed with 18 years of traditional weights based training to innovate and create their very own unique set of training principles and methodologies. Every single workout is personally tested and must tick all these proven boxes before it can be released. Then every aspect of the training system is carefully adjusted using the principle of constant and never ending improvement. Every workout follows these principles. Full body balanced focus in every session. Revolving around 8 key movement patterns. Covering over 9 different phases of training. Across multiple planes of movement (Covering the 3D matrix). We train the cardiovascular, musculoskeletal, fascia and nervous systems all at once across multiple planes of movement covering the 3D matrix. Basically every way the body can move we train it safely under a variety of submaximal loads at different angles tempos with different and unique forces that enable the body to grow, adapt and glue together as one complete robust unit. This specific recipe for training results in a dramatic increase in your athletic potential and abilities and provides you with what we call an elite level of full body strength. Because we are focusing on training over 600 muscles, 360 joints, 900 ligaments, 4000 tendons and 206 bones all at once this powerfully engages, activates and sends the body's adaptation ability into overdrive. This creates incredible levels of internal synergy, a superior level of whole body balance and powerfully links athletic connections in the body for you to enhance your performance. Performance is a simple act of performing a task or function. So this style of training will help you enhance the act of performing any task or function at levels above your current standards. Raising the standards of your everyday actions, tasks and functions will have you enjoying life and ultimately making you happier and healthier. Reality is your everyday actions make up your life and your lifestyle and these little building blocks of behaviors are the most important aspect to focus on to change the quality of your life. We do this safely and strategically via finding your very own unique starting point (USP). Kettlebell Full Body Strength training is the secret to training 50% less and getting 10 times more meaning you can have more time back in your day and your life to enjoy the feeling of being fitter, stronger faster, leaner, more powerful and the added bonus is you increase your levels of injury resilience through the roof.
