Show up. Do your best. UN1T does the rest. UN1T is coached group training built on 12-week progressive programming โ€” strength, conditioning, and a room full of people sweating it out with you. The app is where your side of it lives: booking your sessions, and keeping an honest record of what you're actually lifting. BOOK IN SECONDS Browse your studio timetable and book your class in a couple of taps. Your upcoming sessions sit on the home screen alongside your membership status, so you always know what's booked and what's left on your account. Buy or manage a membership or class pack without leaving the app. Full class? Join the waitlist and we'll book you in automatically if a place opens. TRACK YOUR STRENGTH The six benchmark lifts โ€” Back Squat, Front Squat, Hex Deadlift, Olympic Deadlift, Bench Press and Incline Bench Press โ€” aren't a separate test. They're programmed into every block, so the weights you record are the weights you're lifting in class, and your progression across a block shows up without you having to go looking for it. Log your working weights and watch your tier move: Beginner, Novice, Intermediate, Advanced, Elite. The tier updates live as you enter a weight, so you always know how close the next one is. TRACK YOUR CONDITIONING Conditioning benchmarks are logged alongside your lifts, scored on time, calories or reps depending on the test. Beat your previous best and the app tells you. TRACK BODY COMPOSITION Log body weight, body fat and waist measurements to watch body composition change over months rather than days โ€” the timescale that actually matters. KNOW WHERE THE PROGRAMME IS Your current training phase sits on the home screen โ€” which block you're in, the dates it runs, and the target reps and loading it's built around. Everyone in the room is working the same programme. WE TRAIN AS ONE โ€” An active UN1T membership or class pack at a participating studio is required to book classes โ€” check with your studio before downloading. The app is a training tool, not medical advice: if you have a health condition or you are returning from injury, speak to a doctor before starting a new training programme.

Sports, wellbeing, and team building in one app. Boost your energy and health with regular workouts and exciting sports challenges!

The application captures everyone's contribution in real-time and shows how the team is moving towards the goal. 2. Personal challenges are individual tasks that help each participant achieve personal triumphs and feel the joy of an energetic lifestyle. 3. Corporate sports events โ€” app mechanics allow you to involve participants from different regions and countries in one event. 4. Expert content โ€” the app regularly publishes articles, stories, and video courses about healthy lifestyle, nutrition, motivation, and stress management. 5. Chat inside the application โ€” for communication between participants with experts in nutrition and sports. Other details: - tracking of more than 20 types of physical activity - auto sync with Apple Health and Google Fit, Polar Flow and Garmin Connect - devoted support โ€” operators are available in the app to solve any questions - a well-thought-out notification system so that everyone is updated and progresses toward the global goal - the application complies with the law requirements on the personal data storage Available for corporate clients only โ€” to register in the app, contact your company, university, etc.
