How to Choose:
To choose the right Captains of Crush number, you need to find out how many times you can compress various grippers of other types.
For example, if you can compress a wrist roller with a load of 40 kg several times, then your working number is either Sport or Trainer.
It's important not to overestimate your abilities too much, but it's also not very useful to stay in one place without progress.
Training:
It's important to find the right place in your training for COC.
It's recommended to structure workouts as follows - either after main exercises at the end of the workout or on rest days.
For those taking grip strengthening even more seriously, you will need a training program with Captains of Crush.
Common Mistakes:
Too frequent training. This approach overloads small muscles, ligaments, and tendons of the wrist, leading to overtraining and stagnation.
Only partial closures of the gripper. This technical mistake hinders progress. Remember to fully close your Captains of Crush occasionally.
Excessive load, in this case, using too large a COC number.
