RDX Weight Lifting Belt Eva Curve Rx4

• Stronger, safer lifts: firm core bracing and targeted lumbar support help you squat, deadlift and press with confidence.
• Comfort that stays on: contoured EVA and SpongeX padding reduce digging and pinching so you can focus on each rep.
• Won’t pop open under load: Tension Lock iron buckle and robust Hook & Loop closure keep the belt secure through heavy sets.
• Dialled-in fit in seconds: micro‑adjust tightness between warm‑ups, top sets and conditioning work without breaking rhythm.
• Built for brutal training: durable polyester shell, reinforced nylon webbing and double stitching stand up to long lifting cycles.

RDX Weight Lifting Belt EVA Curve RX4

Chase PRs without compromising comfort. The RDX Weight Lifting Belt EVA Curve RX4 is a lightweight, contoured gym belt engineered to stabilise your midsection and support your lower back when the weight gets real. Its curved profile follows your natural shape, while layered padding delivers the sweet spot of comfort, mobility and support across squats, deadlifts, rows, presses and high‑intensity strength sessions.

Powerful bracing without the bulk

Stiff leather belts can feel restrictive. The RX4 blends a hard‑wearing polyester outer with a compressed EVA‑LUTION™ inner sheet and SpongeX cushioning for a slim, responsive feel. You’ll brace harder, maintain position, and move smoothly rep after rep — with less digging, pinching or distraction.

Locked-in security on every lift

• Tension Lock technology combines a heavy‑duty iron buckle with an anti‑open design to resist belt pop when the bar gets heavy.
• Hook & Loop closure and a reinforced nylon strap let you fine‑tune tightness in moments for different lifts and breathing patterns.
• Double‑stitched webbing increases durability through demanding training blocks and high‑rep work.
• Extra lumbar padding supports your natural curve and helps the belt stay planted set after set.

Why lifters choose the RX4

• Comfort that doesn’t compromise – a contoured fit spreads pressure evenly while keeping your core rock solid.
• Lightweight and breathable – easier to move and breathe than many stiff leather options, ideal for mixed training days.
• Versatile across disciplines – perfect for bodybuilding, strength training, cross‑training and home gym workouts.
• Quick, precise adjustments – micro‑adjust between warm‑ups and heavy sets for consistent bracing.
• Standout style – available in vibrant colours to match your kit and boost confidence on the platform.

How to wear for best results

1. Set the rear pad over your lumbar region and position the front just above your navel.
2. Take a deep breath, brace your core, then tighten using the iron buckle and Hook & Loop until snug (secure but comfortable).
3. Micro‑adjust tension between movements and sets to suit the lift and your breathing pattern.

Who it’s for

Intermediate to advanced lifters who want a gym belt for back support that’s secure, comfortable and fast to adjust. Ideal for progressing compound lifts, chasing new personal bests, and adding core stability during higher‑rep training.

Size & fit tips

• Measure around your waist at navel height (where the belt sits), not your trouser waist.
• If you’re between sizes or prefer a tighter brace, choose the smaller size.
• Designed for a snug, supportive fit you can tighten or loosen quickly between sets.

Care

• Wipe down after training with a damp cloth and mild soap.
• Air dry fully before storing. Avoid machine washing and high heat.
