7 months ago, we sought out to begin developing our own, custom application to revolutionize the way athletes train. Well, the BETA version of our app is now here and we want to share it with you!
1. This new app is home to our year round, unique, 3 program system built and progressed for all athletes. Youth, in-season & off-season programs are available for all athletes!
2. Our easy to use interface allows users to navigate their programs, all containing needed elements for sprinting, plyometrics, agility, strength training, conditioning, mobility and more
3. Our new app seamlessly tracks and calculates your training loads and in later versions, will automatically adjust and re-calculate your “one rep max,” and subsequent training loads based on the prescribed amount of reps!
4. We offer unique workout history tracking where you can easily find and search any date you trained, find the weight you used and optimize your loading for all exercises
5. Gone are the days of using your watch or forgetting to set a timer for your rest. We prescribe the rest, the clock counts down for you immediately after finishing an exercise. Easy as that
6. Video demos for every exercise complete with cues, directly in your program. Know what to do and how to do it
7. Track what matters, understand your improvement. We track and timestamp your performance in valuable areas and with important metrics so you can see your sprint, strength and jump improvements over time
🔜 Coming soon: we are currently developing many cool features, including a virtual coach built off AI technology, a categorized video library of over 700+ video demos, an in-app store with user discounts AND an ecosystem for other gym owners, coaches and professionals to host their own training for their athletes and clients!
We are so excited to revolutionize remote training for athletes and coaches alike!
