In general, it is not even bad, I would advise everyone to take a large 30 kg at once, so that there would be room to grow. The forearms almost do not strain, but the brush can be worked out

Works amazingly! What is needed for armlestling!

Sent in a little more than a month. Packed in foam film, condition is excellent. Looks pretty. Like all spring simulators, the effort builds towards the end. You can train both pronation and supination. 30 kg with some margin for the future, but it's good that I didn't take 20 kg, it would be clearly not enough.

An excellent trainer for the forearms, you can pump the pronators and support the forearms, as well as the adductor and brush muscles. 30 kg is the same, less-it will be rather weak. Instant delivery, 12 days before Novgorod

For his own money performs the functionality required of him. One of the few truly worthwhile exercise machines! Recommend!
