Lattice Training Heavy Roller Portable Wrist Training Device

Season:SS25

Brand:Lattice Training

Code:HeavyRoller164

The Heavy Roller is a wrist training device designed to develop grip strength using an offset loading mechanism.

By squeezing the device and working your wrist against the direction of spin, you can target your forearm flexors or extensors.

To use the Heavy Roller, start by wrapping the cord partway around the device and attaching weight. This setup creates an offset load that generates rotation as you lift. Gripping the device tightly to resist this rotation works your forearm and wrist. Depending on the direction you’re working against, you’ll engage either your wrist flexors (by curling your wrist inward) or extensors (by extending your wrist outward), effectively targeting these muscles for strength development.

The Heavy Roller allows you to train your forearm flexors and improve grip strength with reduced strain on your fingers. The force is distributed across the palm of the hand. Unlike traditional hangboarding, the device targets the forearms, making it an ideal tool for those looking to build strength without overloading the delicate finger tendons.

Free weights, like the Heavy Roller, require your body to maintain control over the weight in multiple planes of motion. Free weights force your muscles to balance, coordinate, and stabilise the load through the entire range of motion, working the smaller muscles in accessory to the forearm flexors/extensors.

Regular use helps ‘bulletproof’ the wrists, reducing the risk of injury. Additionally, the device can be effectively used for rehabilitating existing injuries, such as wrist injuries and tendonitis (such as golfers/tennis elbow), by providing controlled, progressive loading to the affected area.

Climbers know that slopers require a unique kind of strength, particularly in the forearm and wrist muscles. The Heavy Roller mimics the demands of sloper grips by engaging the same muscle groups used in open-hand positions. By training off-the-wall with the Heavy Roller, you can build the necessary strength for tackling slopers without wearing out your skin on friction-y holds. The device’s high-friction powder-coated finish ensures a secure grip, even during the sweatiest workouts, making your training both effective and comfortable.

The Heavy Roller is built for comfort and durability, ensuring you can stay consistent with your wrist and forearm training. Through product research, it has been found that its large 60mm (2.4") diameter is the most comfortable size for grip. The high-friction, powder-coated finish provides a secure hold, even during sweaty sessions, while also protecting your skin from unnecessary wear and tear. Durable construction ensures the Heavy Roller is built to last. Adjusting the load is as simple as adding a weight plate, making it more convenient than managing multiple dumbbells. When paired with a Lifting Pin and Fractional Weight Plates, you gain precise control over the load, allowing for small, incremental adjustments to perfect the intensity of your training.

Features:

  • Isolate the forearm: Target your grip strength with reduced load on the fingers. Ideal for climbers looking for an alternative to hangboarding.
  • Super sloper strength: The Heavy Roller stimulates the same forearm and wrist muscles needed for slopers off-the-wall so you can save your skin whilst training for those tricky holds.
  • Comfortable diameter: A 60mm (2.4") diameter is the comfiest grip size for wrist curls.
  • Max load: 80 kg / 176 lb.
