About this item
- ADJUSTABLE 44–154LB RESISTANCE — Dial up or down with precision using the knurled resistance disc. Whether you're recovering from injury at low resistance or an athlete training for climbing, martial arts, or combat sports at maximum load, one grip strengthener covers every stage of your development.
- BUILT BY SOMEONE WHO TRAINS — The N.T.R.L. grip strengthener was developed with input from a former professional wrestler and qualified personal trainer with 35 years of gym experience. This isn't designed by a marketing team — it's designed by someone who has trained seriously and knows what breaks, slips, and fails.
- REINFORCED COMPOSITE FRAME WITH ALLOY STEEL SPRING — High-strength plastic frame won't crack under repeated heavy use. The flexible alloy steel spring delivers consistent, smooth resistance without the snap-back of cheaper coil springs. Non-slip textured handle keeps your grip secure through high-rep sets and sweaty sessions.
- FOUR TRAINING METHODS IN ONE TOOL — Reps, holds, pulses, and negatives. Each method targets grip endurance, strength, or control differently. A weekly training template is included so you know exactly how to programme your sessions — not just squeeze and hope.
- SUITABLE FOR REHAB, SPORT & DAILY PERFORMANCE — Used by climbers, guitarists, martial artists, office workers with repetitive strain, and athletes in recovery. Compact enough to use at a desk, in a car, or on the go. 30-day hassle-free returns — if it's not right, we'll sort it.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
