Isometric exercises in comparison with dynamic exercisesfrom wiki.
Isometric exercises have some differences in training effect as compared to dynamic exercises. While isometric training increases strength at the specific joint angles of the exercises performed and additional joint angles to a lesser extent, dynamic exercises increase strength throughout the full range of motion.[citation needed] Generally speaking however, people who train isometrically don't train through a full range of motion as the strength gained at the training joint angle is where they require it. Interestingly, a study has shown that while dynamic exercises are 5% better at enhancing the twitch force of a muscle than isometric exercises, isometrics are 32% better than dynamic exercises at increasing maximal muscle power.[7]
ok.Originally posted by eagle:If you have been to the army, they will teach you three ways of training chin ups, of which, one is isometrics. You hang there with your arm at 90 degrees.
The other way is just do the chin ups
And the final way, which I have forgotten the name, is to do a chin up (assisted if cannot do), then slowly let yourself down. Slowly.
