Authentique prone leg curl machine

The Authentique prone leg curl is a professional machine for training the posterior thigh muscles through a guided flexion and extension of the legs. The exercise isolates the hamstrings without involving the lower back, which is the reason a dedicated curl machine remains in every serious strength equipment list: the same movement performed with free weights invariably recruits the lumbar extensors and stops being an isolation exercise.

Authentique is our most recent strength range, with an analogue load counter, a considered finish and a build specification that emphasises reliability, solidity and robustness. We are one of the few companies offering longer warranties on professional machines, which reflects the steel and leather grades used and the standards the equipment is built to. For a buyer, warranty length is one of the few objective signals available before a machine has been in service for a year.

Technical specification

Professional use

A leg curl belongs in any facility that trains the lower body seriously, for two reasons. In hypertrophy and physical preparation programmes it is the only practical way to load knee flexion in isolation. In injury prevention and rehabilitation it is the machine used to address the hamstring to quadriceps strength ratio, which is a recognised factor in hamstring and knee injury risk, and which cannot be measured or trained without a station that isolates the movement.

Exact dimensions, load range and adjustment specifications for this reference are confirmed at quotation stage against the current Authentique specification, so the machine is matched to your room and to the rest of the equipment list. We supply a complete range of professional equipment to clients fitting out a strength area, with attention given to material quality and resistance, to ergonomics and to ease of use for the end member.

Frequently asked questions

How much space should be allowed?

A leg curl needs clear access at the entry side and rear clearance for servicing. Because the footprint depends on the configuration supplied, we produce a layout study for your room as part of the quotation, positioning the machine against circulation routes and neighbouring equipment.

What does the analogue counter do?

It displays the load setting on the machine itself, which speeds up load selection and lets an instructor record a member’s working weight without a separate note.

What warranty is offered?

Warranty runs from 2 to 5 years depending on the range, and we are among the few suppliers offering extended cover on professional machines. Quotations are issued within 24 working hours from our base in Tours.
