Developed by professionals - focused on simplicity. MATS combines sports science principles with technological excellence to help you better plan, analyze, and understand your training. Here's how: โ€ข All-in-one solution - training can be very complex, which is why your training platform should have one goal: To make life easier for you (and your coach). Managing your training process with multiple tools and apps is annoying and inefficient. With MATS, seven previously separated tasks are now part of one complete solution. โ€ข Design simplicity - are you overwhelmed with the complexity of most training and diagnostics tools, including their confusing statistics and charts? We believe that a great training platform needs to be technically advanced, but also easy to use, which is why design simplicity is a core focus for MATS. โ€ข Evidence Based - in your quest to achieve optimum performance, MATS supports you with valid data and our evidence based diagnostic tools. Elevate your training through the implementation of the most up-to-date and relevant scientifc concepts, and make progress comparable and transparent. What's in it: 1. Calendar - plan, track and monitor your training in a central log. Upload files manually or synchronize with your favorite sports tracker. Add events and availibility to your calendar, plan ahead with local weather data, or invite a coach to your calendar 2. Analysis - dive into the details of your performance and understand your progress with the help of scientific analysis tools. View summaries, analyze training intensity distribution patterns, and monitor your training load with the innovative MATS Score. 3. Strength & Core - build and save your own strength routine or train with a workout form the extensive MATS Strength & Core library. Increase effectiveness with detailed instructions and workout videos. 4. Remote Diagnostic - Follow the diagnostic protocol, upload your workout file, and conveniently determine your performance parameters from home. Compare progress over time with your result library and share the diagnostic results with your friends. 5. Training Plans - train with a plan from one of our many professional coaches.
