Strong Mums: postnatal strength training.

Rebuild your strength, confidence and energy after having a baby — with expert coaching and support, in an environment designed for you.

At Joy, we understand that returning to exercise postnatally can feel overwhelming. That’s why Strong Mums offers two ways to get started, depending on what feels right for you.

We know this stage of life isn’t predictable.

  • Nannies are available during sessions

  • Your baby can stay close or be cared for

  • Feeding, changing, settling — always welcome

This is a space where you don’t need to choose between looking after yourself and your baby.

Option 1: Weekly Strong Mums Classes

Flexible. Supportive. Start anytime.

Our weekly classes are designed to help you ease back into strength training at your own pace — with no pressure to commit to a full programme.

  • Postnatal-safe coaching, including core and pelvic floor support

  • Pre-crawlers welcome in sessions, or crèche available

Our 6-week programme offers a more structured approach, helping you build strength and confidence progressively with a consistent group and expert guidance.

  • Small group coaching for a more personalised experience

  • Progressive programming to support safe, steady progress

  • Focus on technique, core recovery and full-body strength

  • Designed to prepare you for ongoing strength training

Perfect if you:

  • Feel unsure what your body is currently capable of

  • Feel ready to commit to a more structured plan

  • Want a clear progression and routine

  • Thrive in a consistent small group environment

Strong Mums Foundations Programme

Developed in collaboration with pre- and post-natal specialist Rachel Prince, Strong Mums is a 6-week, small-group course designed to help you rebuild your body with confidence — and prepare you to transition into our SGPT classes safely and effectively.


A Science-Led Starting Point.

We begin with a detailed intake form, followed by a group consultation with Rachel.

In this session, you’ll:

  • Understand your current breathing and pressure management strategy — and how this is impacting your core and pelvic floor

  • Receive a diastasis recti check and guidance on what it means for your training

  • Learn how to use positional breathing techniques to improve core function, pelvic floor coordination and mobility

  • Identify your current movement limitations

  • Begin to understand how to adapt exercises for your body, so you get the most out of every session

This sets the foundation for everything that follows.

The 6-Week Programme.

Across 6 weeks, you’ll attend:

  • 2 coached sessions per week

  • In a small group of just 6 women

Each session is designed to:

  • Rebuild core and pelvic floor function

  • Improve movement quality and coordination

  • Gradually reintroduce strength training

  • Build confidence in your body again

You’ll be coached closely throughout, with exercises adapted to your individual needs as you progress.

Ongoing Support.

You’ll have access to a private WhatsApp group with Rachel and Joy Founder Jen throughout the course, so you can:

  • Ask questions

  • Get reassurance

  • Feel supported between sessions

You’ll also receive a postnatal recovery guide to deepen your understanding and support your progress outside of the studio.

The Goal.

By the end of the 6 weeks, you will:

  • Better understand your body and how it functions

  • Feel stronger and more confident in movement

  • Have a solid foundation to progress safely and be ready to transition into our SGPT classes.
