About this app

Welcome to The Mill Training App — your digital home for training, coaching, programming and progress.

Created by The Mill in partnership with Fitr, the app brings our coaching and programming directly to you, wherever you train. Whether your goal is to build strength, improve your fitness, prepare for HYROX, develop your conditioning or simply become fitter and healthier, The Mill Training App gives you the structure, guidance and accountability to keep moving forward.

YOUR TRAINING, ALL IN ONE PLACE

No more guessing what to do when you walk into the gym.

Your training programmes are delivered directly through the app, giving you clear sessions to follow, exercises to complete and targets to work towards.

Access your training whether you're at The Mill, at home, travelling or training somewhere else. Your programme stays with you, helping you maintain consistency wherever life takes you.

Depending on your programme, you can access:

- Structured training programmes
- Individual workouts and sessions
- Exercise demonstrations and guidance
- Sets, reps, weights and targets
- Training history and completed sessions
- Progress tracking
- Strength and conditioning programming
- Functional fitness training
- HYROX-focused programming
- Coach-led programmes
- Training notes and feedback

COACHING THAT GOES BEYOND THE GYM FLOOR

The Mill isn't just about giving you a workout. It's about giving you a plan.

Our approach is built around structure, coaching, accountability and progression. Your programme provides the direction, while our coaches provide the knowledge and support to help you execute it effectively.

Depending on your programme, you may receive coaching feedback, check-ins, programme adjustments and ongoing support to help you continue progressing.

BUILT FOR PROGRESS

Progress comes from consistently doing the right things over time.

Use the app to record your training, track your sessions and build a clear picture of your progress. Record the weights you lift, the reps you complete and the sessions you finish, allowing you to look back at your training and see how far you've come.

TRAINING FOR EVERY GOAL

Whether you're looking to build strength, improve your fitness, prepare for HYROX, improve your overall health, build confidence in the gym or take your performance further, our programmes are designed to give you purpose and direction.

At The Mill, we believe effective training should be structured, sustainable and enjoyable. We don't believe in quick fixes or constantly jumping from one workout to another. We believe in having a plan, executing it consistently, learning from your training and making adjustments when necessary.

POWERED BY Fitr

The Mill Training App has been developed in partnership with Fitr, combining professional digital training technology with The Mill's coaching expertise.

Fitr provides the technology that allows us to deliver your programmes, organise your workouts, track your training and connect you with your coaching experience digitally.

Together, The Mill + Fitr give you a simple and effective way to access high-quality training wherever you are.

Your training is more than a workout.

It's a process. It's progress. It's The Mill.
