Si-Club and Macebell are off-centre weighted implements that require neuromuscular control across multiple planes of movement: technical tools for those working on mobility, functional strength and coordination using progressive loads.
Off-centre weighting for muscle stimulation that cannot be replicated with traditional equipment
The range is available in a variety of sizes: from lightweight models designed for mobility to heavier Macebell models designed for strength
Suitable for fitness trainers, CrossFit boxes, personal training studios and advanced home gyms

Si-Club: the Sidea selection
The Si-Club tag groups together Sidea equipment with a distal centre of gravity: clubs (clubbells or Indian clubs) and macebells, including the variable-load model. What these implements have in common is the physical principle of off-centre weight: the centre of mass is located away from the handle, generating forces of torsion, leverage and rotation that the athlete must actively control. This mechanism engages the kinetic chain differently from barbells or dumbbells, making these pieces of equipment effective for developing shoulder mobility, core stability and inter-system coordination in the sagittal, frontal and transverse planes.
Who is Si-Club for?
Fitness trainers use them during dynamic warm-ups or as a tool for active mobility in strength training sessions: just 5–10 minutes of swings and circles with a 1–2 kg club are enough to activate the rotator cuff in a progressive and non-invasive way. For CrossFit boxes, they represent a form of conditioning that works on anti-rotation and eccentric control, often incorporated into GPP programmes.
Personal training programmes incorporate these exercises into functional rehabilitation protocols and shoulder injury prevention programmes, where sports literature indicates that off-centre weight training is an effective complement to traditional resistance training. Those who train in <a href=

Claves are conical or bottle-shaped implements, mainly used in pairs for circular and oscillating movements that engage the shoulders and wrists. The macebell, on the other hand, has a spherical head on a long, rigid handle: it is often used on its own for swings, presses and rotations that engage the entire kinetic chain. The two implements have slightly different learning curves and objectives, although they share the principle of off-centre weight.
-
For those new to this technique, 4–6 kg is the recommended starting point, regardless of your overall strength level. The macebell immediately penalises anyone who tries to use too much weight: the long lever arm magnifies postural errors and requires you to develop control of the pendulum first, before gradually increasing the load.
-
Yes, it is one of the most established uses. 3–5-minute sessions with light clubs (1–2 kg) before barbell or kettlebell sessions prepare the rotator cuff, increase the local temperature of the shoulder and improve proprioception of the glenohumeral joint. Several StrongFirst protocols include this type of pre-session activation.

The Sidea Loadable Macebell is designed to accommodate standard weight plates. However, before purchasing, it is advisable to check the product’s technical specifications in the product details page, as the shaft diameter may vary between models. For technical enquiries, the Sidea team is available to offer direct advice.

In the field of rehabilitation, off-centre weight training is used by physiotherapists and sports coaches as a tool for the progressive strengthening of the rotator cuff and for re-educating motor control. However, this type of use requires supervision by a qualified professional: the equipment alone does not constitute a rehabilitation programme.
-
The basic movements of Indian clubs are easier to learn by starting with a single club, so as to focus on the mechanics of the movement. Bilateral practice with two clubs is a subsequent step that requires more developed inter-hemispheric coordination. For this reason, many people initially buy a pair but train asymmetrically during the first few weeks.
