Power+UP! Is a physical strength development platform driven by the principle goal to Exceed or Maintain Total Resistance Weight Lifted for each and every exercise in your plan, based on your previous efforts data. Progressive overload theory applied to all gym weights and body weight exercises, inclusive of Weightlifting and Body Weight Only plans as well. Why this approach? It is the only proven approach for measurable gains and maintenance. Unlike traditional workout routines and apps that emphasize predefined sets and reps, we ensure progress for both novices and experienced lifters by dynamically adjusting your sets, reps, and weights to meet your specific goals. Highlights: Exercise-Specific Total Resistance Weight Focus: * Achieve your personalized target strength-maintenance goals by lifting a specific total resistance weight for each kinesiology-approved exercise. * Track and beat your total resistance weight lifted during strength development weeks, and match it during maintenance weeks. Dynamic Performance Coach: * Receive real-time set suggestions and adjustments to sets, reps, and weights to help you reach your total resistance weight lifted targets. * Customize rep range targets to trigger weight increase or decrease suggestions for optimal growth. * Set guidance dynamically adjusts with every completed set to ensure you meet exercise-specific resistance targets. * Real-time coaching on sets, reps, and weight needed to achieve your desired resistance targets. Efficient Training Guidance: * Exercise-specific set timers provide precise guidance for active and rest periods, maximizing your training efficiency. * Default timers are 40 seconds active and 60 seconds rest, adjustable to match your desired pace. * User feedback shows a 30-50% reduction in overall workout time, making your training more efficient.
