Crux ARO Hard Handtrainer

ARO hard has a resistance of 27 kg. As the stiffer version, it is ideal for a more advanced phase of finger and forearm warm-ups, or for training grip strength.

To make your warm-up more progressive, you can start by using ARO soft and then increase the resistance with ARO hard.

Depending on your strength, you should adjust the type, soft or hard and the way you use it to achieve an appropriate warm-up or training session.

To warm up before climbing, squeeze it repeatedly to progressively activate tendons and muscles, reducing the risk of injury. It is recommended to do this with low resistance.

Changing your grip position, speed, or rest intervals will allow you to gradually increase resistance to effort, increasing muscular and tendon stress as the warm-up progresses.

If you want to train grip strength and forearm muscles, it is better to do fewer repetitions with more resistance, and when you open your hand, do it slowly. Instead of doing many sets in one day, it is better to do 3 sets with each hand several times per week.
