GD IRON GRIP Pinch Grip Set (Rock Climbing Grip Trainer) Grip Strength Trainer Adjustable Hand Grip Strengthener Hand Grip Exerciser Strengthener Wrist Strengtheners for Climbing Finger Training

It's extraordinarily made, well designed, perfectly finished. I STRONGLY recommend this to all.

Great product. Lost one star because the black coating peels a bit where it contacts the spring and because the knurling is too rough.

Excelente calidad pero resulta necesario usar straps para poder hacer más repeticiones.

Nice product

This thing is sick. If you're into grip training for sports like BJJ, climbing, golf, maybe injury recovery, or just to build your spaghetti arms, save up and buy this one. Pulling this out of the box feels like picking up a specialized aircraft part. It is so solid and well made, the fit and finish is quality all around. No sharp edges, burrs, or rattle. The corners are all nicely eased and chamfered. The knurling is every bit as good as a high end shop tool or your favorite barbell brand. The fasteners for accessories are held in with hex bolts, Allen keys included. Even the Allen wrenches are plated! The range and type of adjustments are huge! 1) By changing the spring angle, you can select between 55lb (25kg) and 198lb (90kg) in five steps. It is easy to do and the instructions are clear, with color pictures and in correct English. 2) The grip distance can be adjusted between three levels, which also changes the overall travel distance. This is great for people with smaller hands that can't reach the full distance, however, it can also be used as part of a training program while working up to the next resistance level. 3) The grips have extension caps that make the grips longer, therefore providing more leverage. I'm not a climber, I got this model because it has 90kg max weight (versus 80kg). That said I tried the climbing/finger strength attachments. They are also well made, glass filled Nylon I believe. Two stainless steel screws come out, then install the extension caps and the finger trainers, and a longer bolt goes in. Just on the lowest resistance setting I could feel that this would help if pulling myself up by my finger tips was something I did in life. PROTIP: When training, do sets with the device with the springs upright, and with them downwards. This works different parts of your muscle & tendon chain. Do this with regular squeezes, isometric holds (holding it fully compressed for a set time or until failure), and concentric (negative) only focused movement. This variety of work will improve both your strength across the grip range, and your capacity to hold weight for longer durations. To really trip yourself out, try putting your forearm down on a surface with your wrist over the edge, and rep the device with your wrist flexed upwards, then try it with your wrist flexed downwards. The difference in your ability to apply grip pressure based on wrist position is wild and something to experiment with.
