The Sparkfield Core strength training device combines cutting-edge robotics technology with effective training methods. At the push of a button, it delivers the training quality of a premium fitness studio, covering all muscle groups, including the "Big Five" (squats, deadlifts, bench press, rowing, and shoulder press). Sparkfield Core continuously evolves: new exercises, training methods, and analysis features can be added as apps at any time. Its flexible kinematics already enable 20 exercises, with more in development. Electric drives precisely control the resistance, supporting advanced techniques like eccentric overload, supersets, and isometric training. Variable resistance profiles optimize training for both beginners and advanced athletes. Precise force measurements ensure accurate control of exercise execution and muscle load. Sparkfield Core dynamically adjusts the resistance, maximizing training efficiency and safety.
