LogestMetal Hand Grip Strengthener 100LB-350LB No Slip Heavy-Duty Grip Strengthener with Gift Box, Great Wrist & Forearm Hand Exerciser, Home Gym, Hand Gripper Grip Strength Trainer

I've been into weightlifting since I was a kid. It's helped me to stay healthy throughout my life and as I age I've slowly shifted focus from strength training to endurance drills. I've had a number of hand grips over the years and eventually they lose tensile strength and they snap. I ordered these just as my old grip broke. I assumed they would be no different from the old one. I was wrong.My previous grips were 150 lb resistance. I have used them at that level for so long that they had become routine. I still have one of them at the level so I thought I'd ordered the 200 lb grip as a challenge. At first the grips seemed a little tight but after a few rounds they sort of "broke in" and were smoother during reps. I was pleased with the result and after alternating hands for ten minutes at 25 reps per I felt a little worn but not in a negative way.The material used with these grips are superior. I prefer the regular means of generating resistance with a coil rather than a spring. The coils just last longer as well as provide a more solid level of resistance that the spring type grips just lack. The grip has some weight to it and the heft is quite comfortable. I've owned grips with plastic handles and it just doesn't feel right. I prefer the metal base rather than just cut steel wire. It just feels more natural in the hands. While these are not through and through I've always preferred the steel handle even if it is separate from the grip and not machine knurled.The resistance on the 200 lb grip is not for beginners. It is a lot more resistant than one might think. It is not commensurate with your benching weight. You should use a pair that you can not quite close when you start out regardless of your hand strength. These grips fit that bill if you are already an experienced weight trainer. The grips do come with sleeves and while the material is comfortable I don't see them lasting the life of the grip. Without the sleeves I imagine the grip is somewhat uncomfortable particularly if you don't have calloused hands. I would suggest trying the 50 lb for beginners and the 100 lb for intermediates. The 200 lb provides more than an adequate workout for the experienced weight trainer. This series goes up to 350 lbs so if tearing phone books or sheep shearing are your thing then this series will have you covered.I was completely satisfied with my order. These grips are well made and once you find the level of resistance you require will pay dividends to realizing a proper weight training strategy. They pair well with Baoding balls in giving you the warm-up, workout, and cool down you will need to realize your goal of hand strength and flexibility. The price point is quite fair for the quality and utility that you get with this product and with that I'd recommend these to anyone wishing to further their health and keep a proper balance to the normal wear and tear of aging.

Cumple con lo que dice, materiales de muy buena construcción, bastante difícil de cerrar y trae agarres alternativos

I sent this back. Although I train on weights regularly, I could at best manage only seven reps and with that I could feel the strain on my wrist tendons. Not worth an injury just to keep up with the boys on supplements. Seriously, you need to have gorilla level strength to work this device. I cannot even fathom the strength needed to work the 150 or 200 lb devices. I might try the 50 pounder. Apart from the above, it seemed to be a well-designed unit.

Works as intended. The insides of the black grips do fray tho

Great quality product. 100 lb resistance certainly provides workout for grip strengthening.

Feeling a bit cocky I ordered the 250 suspecting the levels might be inflated (like flimsy grips). But this grip is for real; it is kicking my backside. Very well made.

Should've went one lbs less than what I bought.

It was an excellent product until after a week of use 2 out of 3 of the grip strengtheners stared to make really annoying creaking sounds
