Muy buen producto

Beware
It does not seem to be as hard to bend as it was made out to be. I even bend it in reverse.

It works as intended, but i definitely don't see the 130lb resistance advertised. It would be very helpful if the kit included some instructions for different workouts. But its a good piece of equipment to keep around the house to play with while you are watching TV.

Decent resistance
My son uses this during baseball season. It offers decent resistance, but I've found that he really prefers to work with bands. I think this doesn't offer enough versatility in exercises for him.

For bigger arms you need bigger forearms
Was browsing around Amazon and passed over this. Then I realized I've been looking for an alternative forearm workout. Went and ordered this and this does what I've been looking for. For those that don't know, the size of your upper arms (biceps & triceps) are limited by the strength of your forearms. In other words, if you can't pick up and hold the weights, you can't use them to work out with. Or conversely, if your forearms tire before your upper arms, you've just wasted your time because you didn't take your upper arms to exhaustion. 👉NOTE - I am NOT a trained professional. The following information is for entertainment purposes only! I do not feel comfortable using only one spring, it doesn't feel like it is in proper alignment with my body in any way. I start with the twister in front of me, elbows at the sides, gripping the rounded ends. The force adjustment buttons are set to the inner ones to begin with. Now, keeping your elbows at your sides as still as possible, move the ends towards each other in front of you. If you can't do this, try the force buttons at their outer position (more leverage = less force). I shoot for reps until exhaustion while keeping form. Reduce the force (outer buttons) and repeat. Then I go back to the inner buttons and instead of reps, I do a timed hold. Repeat for the outer buttons and that's it for me. Do what works for you. Just remember to keep your form. If you need someone or something to help get past the initial start position, there's no shame in that, just watch and keep your form. If you're wondering what happens if the outer grips are too easy for somebody, they just go to the inner ones. That's where the 130lbs of force is if you didn't know. For what it's worth, I'm still doing my biceps and triceps with free weights. I don't feel that this piece of equipment allows my body to be in the right position for maximum muscle growth. It doesn't allow me to do the movements I want without engaging other muscles due to the layout of this twister. In conclusion, this is exactly what I was looking for for targeting my forearms. I wasn't interested in doing fingertip curls or anything similar to that. I may have to change it up down the road at some point but it's working for me right now so I'll ride with it. ... show more

Way too much resistance for my flabby arms
This came in a cardboard box unassembled. Assembly takes just a couple minutes as there are only 4 pieces. The problem I had with this was very similar to the other one I tried - it had WAY TOO MUCH resistance to even bend it reliably. They need to make a wimpy version of this product. If you're already pretty strong, you should be ok as it comes out of the box, but if you're an average American, probably going to have issues. ... show more

Not easy in the beginning, but once you get used to it, it definitely gives a great workout. Give it a try!
