Retain and attract clients with the portable Marsden U310 Body Analyser
Today’s clients expect more than just workouts. They want measurable results, clear progress tracking and guidance that’s tailored to their performance, as standard.
However, for gym staff and personal trainers (PTs), delivering this level of insight in a clear and consistent way for every client and workout takes additional time and effort.
Introducing – the Marsden U310 Body Analyser
Weighing just 2.2kg, the U310 delivers full-body and segmental composition analysis in less than 30 seconds. Using advanced Bioelectrical Impedance Analysis (BIA), it provides professional-grade insights that rival larger clinical devices without sacrificing portability.
Key metrics include:
- Muscle & fat distribution - track lean mass and fat levels, using arm, leg and trunk measurements
- Visceral fat & obesity indicators - assess health risks that may exist beyond the surface
- Body water & bone mass - gain a complete picture of client wellness
- Basal metabolic rate & body age - demonstrate how lifestyle impacts long-term fitness levels
Designed for gyms, built for trainers
Whether located in a consultation room or carried around by PTs from session-to-session, the UL310’s lightweight design makes professional analysis available anytime, anywhere. 
All of the results sync instantly to the Charder ProScan app, storing unlimited data for seamless trend tracking. Trainers can pull up progress charts in seconds, helping clients stay motivated and committed.
Tracy Stanbrook, Head of Sales says: “The gym and personal fitness sector has never been so competitive, and being able to clearly demonstrate real value to clients has never been so important.
“The U310 provides PTs with an instant credibility boost that can be accessed anytime, anywhere. What’s more, it’s backed up with scientific evidence that instantly enables gyms and PTs to provide a value-added service that’s capable of retaining existing clients by keeping them motivated and attracting new clients by offering the very latest 21st century data-driven insights.”

For large gyms and health clubs, the U310 offers a point of difference within a competitive market:
- Boost retention - keep members engaged with visible progress
- Personalised programming - base training plans on real data, not guesswork
- Upsell opportunities - offer premium body composition assessments as a paid add-on or bundle into memberships
