On what basis are isometric exercises better? You might as well say that standing is better exercise than running. For injury prevention? Maybe. For health and fitness? Not so much.

- pringlepong 4y agoHave you ever held a plank for, say, 60 seconds? I can't imagine someone who has suggesting that planks are to situps like standing is to running.
- scoot 4y agoYes. Ten minutes is my record. (That was the target, didn't aim for longer). The point is that static exercise only builds strength at the particular muscular extension tested by the exercise. With planks your core remains weak for anything that doesn't resemble a plank, just as standing doesn't meaningfully improve your running.
