Recently while grappling my forearms have been burning out really fast. I don't gas out, just my forearms and it makes gripping and finishing harder. What are some exercises that I can do at home to increase the stamina in my forearms?
Another exercise you can do to build endurance is to rapidly close and open your fingers, for repetitions in the dozens or hundreds.
It doesn't seem like much of an exercise at first, but it does require and develop endurance. Some very, very strong judo men have done it as a part of their training.
