What is gonna be more effective to building mass quickly if you have to choose between isometric vs. isotonic contractions?
Can you give me examples of which one would be better when it comes to bicep exercises for example
and what would also be better on a day that your muscles are more sore? I don't want to do an exercise that will actually end up hurting me
