RDX H2 Neck Harness – Weight Lifting Neck Strengthening Strap for Boxing & MMA Training

The RDX H2 Neck Harness is designed for targeted neck and upper back strengthening — essential for combat sports athletes where neck strength directly reduces the impact of concussive strikes. The harness targets the trapezius, rhomboid, and deep cervical muscles with progressive loading via the 35-inch steel chain. Three-way adjustable straps and under-chin/overhead padding keep it secure and comfortable throughout your workout. Also commonly used for posture correction as well as strength building.

• 4 D-ring latches for adjustability and maneuverability at varying lengths
• 35-inch (90cm) HG steel chain — adjustable and durable with versatile loading options
• Nylon/neoprene industrial-grade stitching for resilience and long-lasting wear
• Three-way adjustable straps for a stable, secure fit during training
• Under-chin and overhead padding for comfort and a secure anchor around the head

Frequently Asked Questions

How much weight can I load on the H2 Neck Harness?

The H2 uses an HG steel chain with a 35-inch length and D-ring latch system, which handles progressive overload well. Start with a light plate and increase incrementally — most athletes work in the range of 5–25 kg depending on conditioning level. Always perform neck exercises through a controlled range of motion rather than maximum load.

Is this suitable for beginners who have never trained their neck before?

Yes, but with caution. Begin with bodyweight neck movements (bridges, isometric holds) before adding any plate weight. When you do introduce load, start with 2–5 kg and progress slowly. The neck contains sensitive structures, so controlled, deliberate movements with appropriate warm-up are essential regardless of experience level.

What muscles does neck harness training target?

The primary muscles targeted are the trapezius (upper and middle), rhomboids, and the splenius capitis and semispinalis — the muscles responsible for neck extension and lateral flexion. Strong neck muscles are associated with reduced injury risk in boxing, MMA, wrestling, and rugby.

Can I also use it for posture improvement?

Yes — neck and upper back strengthening is commonly prescribed as part of posture correction programmes, particularly for people with forward head posture from desk work. Strengthening the posterior neck and upper back muscles helps counteract the pull of shortened chest and anterior neck muscles. Use lighter weights with higher repetitions for postural work rather than maximum-load strength sets.
