Speedflex launches JNRZ youth training programme for ages 10-16

Speedflex has announced JNRZ, a new youth-focused training programme designed to make strength training safer, more inclusive and more engaging for children aged 10-16 years old.

The programme has been developed in line with the latest ukactive guidelines and is built around the Speedflex Blade, which uses adaptive resistance technology to respond instantly to the force applied by each user.

JNRZ has 20 on-demand workouts available directly on the Speedflex Blade. The sessions introduce strength, cardio, coordination and athletic development in an age-appropriate format, with expert-led coaching shown on screen.

Speedflex JNRZ has been created to support young people in a controlled, low-impact training environment.

Unlike traditional weight-based strength training, the Blade does not require weight stacks, plates or manual adjustments. Instead, the system automatically adapts to the effort of the user. For children and young people, this creates a setting where they can train with intensity while reducing the risk of overloading. It also removes the need to change settings between users, making the programme easier for operators, families and young members to use.

“This is a step-change moment for youth fitness,” explains Paul Ferris, CEO and co-founder of Speedflex. “For too long, strength training for young people has either been inaccessible, intimidating, or simply not designed with them in mind.

“With JNRZ, we’ve created a solution that removes those barriers entirely. By combining adaptive resistance with guided, engaging sessions, we’re delivering a training experience that is not only safe for developing bodies, but incredibly effective in helping young people build strength, confidence, and a lifelong connection to exercise.”
