Frequently asked questions : Shoulders
Which muscles does the Shoulder Piston Machine primarily target?
This apparatus focuses primarily on the deltoid muscles of the shoulder and the triceps brachii. The controlled overhead pushing movement also engages the upper trapezius and stabilising muscles of the core, making it an effective exercise for overall upper-body functional strength.
Is the Shoulder Piston Machine suitable for older adults or users with limited strength?
Yes, the 8 adjustable resistance levels make this machine accessible to seniors and beginners who require a lighter workload, as well as more experienced users seeking greater challenge. The ergonomic seat and guided movement path also reduce the risk of incorrect posture, making it a safe choice for mixed-ability public environments.
What type of ground surface is required for installation?
The apparatus can be installed on concrete, tarmac or compacted ground using anchor bolts secured into a concrete foundation. Herkules Fitness provides detailed installation guidelines to ensure structural stability and user safety. It is recommended that installation is carried out by qualified professionals.

How should the hydraulic piston be maintained over time?
