Sidewinder ProXtreme Original – The Ultramodern Finger, Hand, Wrist, Forearm, Fat Grip Strengthener #3, Adjustable Resistance

This is a VERY well-designed product that oozes quality. It is larger than I expected; looks something like an Olympic torch or light saber from Star Wars. It's clear they used high quality components and it operates very smoothly. I honestly thought it a bit overpriced when ordering, but it was so unique and specific to the training I wanted to do that I proceeded. I am so glad I did. Upon opening it and trying it, at first I thought it wasn't difficult enough as I was able to rotate it on the highest level. I was definitely wrong about that, my forearms have never been worked this hard. The pump you get from this is amazing. Even after one set of ten reps in each direction my forearms were bulging out, it's a rather euphoric sight. The lowest setting of resistance is VERY easy so don't hesitate to order this one vs the lesser models; you can buy this and progress as you go, trust me. The interesting thing about the resistance is that on a given resistance setting if you turn slowly it seems relatively easy. If you rotate it quickly in a very determined, focused manner it is MUCH harder to turn. It's almost as though the resistance isn't linear, but ramps up the harder you rotate it. I do eventually see myself mastering this device and needing more resistance, but that is a LONG time off. At present they don't offer a higher model with more resistance, but that's OK. Honestly once I've conquered this and can do multiple high rep sets in quick succession I have no doubt I will have reached a world class level of forearm strength. In my lifetime I've tried just about every kind of grip enhancing device and forearm workout tool; nothing else compares to this device it is as close to perfect for this type if training as you can get. I highly recommend using this in conjunction with pro grade handgrip training equipment such as Captains of Crush for a well rounded workout. You can't properly utilize forearm strength without strong hands; sort of like a high torque car motor is of no use without a good set of tires to put it down to the ground. In fact, if on a tight budget starting out I'd buy COC grippers first, say a 0.5 or 1.0. Master that for a while and then add in the Sidewinder. My fitness goal with this equipment is to improve my competitive pistol shooting and I have no doubt I'm on the right path with this combination. There is also a huge psychological factor to having visibly strong forearms and hands and a solid grip during a handshake. It may sound infantile, but it is true that men instantly judge one another and respect other men who convey strength during a handshake. No, not try to crush the other guys hand, that truly is infantile and works against you. Rather just a firm solid grip and solid eye contact is a requirement if you want to instantly start off a sales call or meeting on the right foot. I know of many well qualified job interviewees and salesmen who are not successful because they don't understand this age old truism. Women also subliminally judge a man by his perceived strength and particularly the strength of a man's hands and forearms. Trust me, having big biceps but weak hands is not impressive and is not real world usable strength. No matter what your overall size or strength goal always work on the foundation: legs, hands/forearms, and core. The rest will fall into place and focusing on those things will give you a solid, usable level of strength and prevent injuries now and down the road. Kettlebell and sandbag training are perfect ways to get that foundation. One of the hardest things with both of those is you need good grip strength while using them and that's where this product can really raise your game. Best of luck to you in pursuing your own goals!

I did quite a lot of research prior to buying my Sidewinder, and the time I spent has paid off handsomely! I'm amazed by the quality, and the fact that nothing rattles or squeaks regardless of the setting. It is a bit expensive, but IMO well worth the money due to the solid construction coupled with the fact that it provides a fantastic workout. After the first proper session my forearms and wrists were so pumped that I could hardly bend my wrists for about ten minutes, and depending on the arm and wrist position, it also gives other areas such as the shoulders, biceps and deltoids a decent blast as well.I'm sure almost everyone who buys a Sidewinder will turn it up to maximum difficulty and try it, and of course I did too. I could twist it on max setting, but cranking out sets would take more power and stamina than I have...for now anyway! I've been doing gripper training for almost 18 months now and can close a CoC #2.5, so I have decent wrist and forearm strength already and well above average grip strength. Despite this, after a good twisting session I can really feel the burn in parts of my hands that torsion spring grippers don't exercise as much. For now I'm using it set to just over half the maximum setting.My wife has health issues, and one of the effects of this is muscle weakness, particularly in her arms and hands. One of the great things about the Sidewinder is the fact it's adjustable: turned down to the minimum setting, my wife can use it for light workouts and has shown positive results since commencing regular use. The fact that it weighs a few pounds also makes her arms work to support the weight of it and it really seems to be helping her. I think she may secretly be excited by its appearance as well.I noticed some of the reviews mentioned people getting rubber particles on their hands when first using their Sidewinder. I did not have this issue and suspect it happens because the average person's grip can't handle the power their arms generate when twisting it, so their hands slip a bit, generate friction, and remove a tiny bit of rubber - stick with the workouts and this baby will give you the grip strength you need.And finally, the fact that it lets me sit in my favourite reclining chair with a beer while I watch TV and totally blast my forearms is definitely a bonus feature :)

Absolutely fantastic product. Shipped incredibly fast, and when it arrived you can see and feel the quality. It has a good deal of heft to it, and a sturdiness that's sadly rarely seen in products nowadays. Definite 5 stars. Leaves my arms feeling like they just went for a 5 mile hike, and even after only a couple weeks I'm already observing benefits of use.
