Krato is the app built by lifters, for lifters. One fundamental thing to know about muscles is that they don't know the weight that's on the bar but they only know mechanical tension Mechanical tension is the ultimate trigger and the vital first step to hypertrophy, running right alongside good nutrition and proper recovery. However, without the right mechanics for an exercise, the target muscle won't be stimulated to grow. That is the exact reason why you feel your traps taking over instead of your side delts when you do lateral raises. If your execution is off, your gains go to the wrong places. Krato fixes this. We bridge the gap between lifting heavy and lifting right. You get: Easy to understand exercise form cues. Science notes explaining the why behind every movement. At 4-step checklist guiding you exactly on how to perform each exercise correctly from start to finish. Beyond perfecting your form, Krato delivers deep analytics on your training data. You get a complete analysis of your muscles, a visual breakdown of the days you showed up, and a detailed look at your progression and RM (Rep Max) history for every single exercise you perform. It’s a tracker, a guide, and a planner all built into one single place. What we aim for is simple: a perfectly executed exercise with the right amount of weight to produce genuine strain and trigger the muscles to grow. It is scientifically proven that maximizing the mind-muscle connection can result in up to 22% more muscle gained. Stop guessing your mechanics, stop wasting your sessions, and start demanding more from every single rep. ¿What makes KRATO different to other apps? While theres many apps in the fitness industry, they all provide a similar approach. Tracking, planning, nutrition. Krato focuses on execution, certain execution and progress. We want you to workout but we want you to workout right Avoid injuries and avoid waisting your time. Start using Krato and start making more progress.
