BLACKROLL® DUOBALL – Trigger Point Therapy for Back & Spine 

Why Choose the BLACKROLL® DUOBALL?

• Designed for effective trigger point therapy and muscle release
• Ideal for parallel muscle lines along the neck and spine
• Gap between the balls reduces pressure on bony structures
• Suitable for back, shoulders, arms, hips and legs

The BLACKROLL® DUOBALL is specifically designed to target parallel lines of muscles, making it an excellent tool for relieving tension along the thoracic and lumbar spine.

The central groove between the two fused balls allows you to massage muscles on either side of the spine without placing direct pressure on the vertebrae — making it a more comfortable option for back-focused recovery.

Also commonly referred to as a peanut massage ball, the BLACKROLL® DUOBALL is designed to safely release muscle tension along the spine.

Targeted Relief for Back, Neck & Spine

The DUOBALL is particularly effective for addressing upper and lower back pain, neck tension and stiffness caused by prolonged sitting or repetitive movement.

It can also be used to treat:

• Upper thighs and hips
• Calves and Achilles tendon area
• Shoulders and arms

For more precise, single-point pressure, you may prefer the BLACKROLL® Trigger Point Massage Ball, while the DUOBALL is ideal for symmetrical, spine-adjacent muscle work.

Evidence-Based Recovery

A scientific study has identified the DUOBALL as a highly effective tool for reducing muscle stiffness and preventing pain symptoms associated with prolonged sitting in the workplace.

This makes the DUOBALL particularly suitable for office workers, remote workers and anyone spending long periods seated.

Different Sizes for Different Applications

The BLACKROLL® DUOBALL is available in 8 cm and 12 cm sizes to suit different body types and preferences.

• 8 cm DUOBALL: Ideal for smaller frames and precise work between the shoulder blades and neck
• 12 cm DUOBALL: Better suited for taller individuals and wider lower back areas

While size recommendations can help, the final choice often comes down to personal comfort and preference.

How the DUOBALL Compares

The DUOBALL complements other BLACKROLL® recovery tools:

• Use a Massage Ball for pinpoint trigger points
• Use a Foam Roller for larger muscle groups
• Use the DUOBALL for spine-safe, symmetrical muscle release
