Starting young, starting safe

Strength training isn't just for adults. When it's suited to their age and abilities, it can help children build strength, improve coordination and become more confident in how they move.

Starting young also gives them a chance to discover the joy of being active and develop healthy exercise habits that stay with them as they grow.

Starting young, starting safe

Is it safe?

Strength training can be safe for children when it's appropriate for their age and abilities, with proper technique and qualified supervision. Speedflex offers a different approach to resistance: rather than selecting weights, the resistance responds to the force applied as they move.

This lets young users control their own effort without changing weights or settings between exercises. With guidance from a trained instructor, they can learn good movement habits and build strength at a pace that suits them.

JNRZ brings a junior-focused approach to Speedflex training,
with age-appropriate sessions designed around movement, fitness and building confidence. Ideally suited for 10-16 year olds.

Make fitness a family thing

Sharing an interest in fitness can help make movement a regular part of family life and give young people encouragement as they build confidence.

  • Choose age-appropriate sessions

    Training should reflect each child's development, ability and experience.

  • Ensure proper supervision

    Juniors should receive guidance from an appropriately trained instructor.

  • Prioritise technique

    Learn the correct movements before increasing intensity.

  • Listen to the body

    Exercise should be challenging but manageable, without pushing through pain or discomfort.

Testimonials

"As an ex-footballer I've had more injuries than most, whether that be ankles, knees or back. I've tried so many different exercise regimes, but nothing compares to Speedflex. I can go hard on this machine and the next morning there's no stiffness or pain at all."

Alan Shearer former England captain and Speedflex co-owner

"It works for any level of person, or fitness. This has kept me fit since I retired 14 years ago."

Dion Dublin Former Premier League Striker

"It is incredible. There is nothing like Speedflex. To train that hard and burn as many calories in such a short space of time anywhere else, for me, is impossible. Speedflex is the perfect system if you want to get into HIIT training."
