ARO soft has a resistance of 18kg, and being the softest version, it allows you to do a gentler warm-up of fingers and forearms before your climbing session. To make your warm-up more progressive or improve your strength, combine it with ARO hard. Depending on your strength, you will have to adapt the type (soft/hard) and the way you use it to perform a proper warm-up or training. To warm up before climbing, squeeze it repeatedly to make a progressive activation of the tendons and muscles, thus reducing the risk of injury. It is advisable to do it with little resistance. Changing your grip posture, speed, or rest intervals will allow you to gradually increase your resistance to exertion, thus increasing muscle and tendon stress as the warm-up progresses. If you want to train grip strength and forearm muscles, it's best to do a few reps with more resistance, and when you open your hand, do it slowly. Instead of doing many sets in one day, it's best to do 3 sets with each hand several times a week.
