The ones I do are mostly heavy isometrics. I do weighted dead hangs for the inside forearms and isometric reverse grip barbell curls for the outside forearms. For the curls I’ll hold at about 90 degrees. For both I shoot for more than 20 second holds with as much weight as I can. The specific exercises aren’t as important as doing something that creates a lot of tension on the tendons you want to work, sustaining the tension, and being safe. The last thing you want is to exacerbate the problem.
Can you link to these tendon exercises?
