Why is isolation work frowned upon so much? There isn’t any benefit in them, but… what really is any downside to doing it? I don’t see any, unless someone’s spending too much time doing isolation work where their workouts are being dominated by isolation work, and that time could be better used in place of compound exercises.
Other than that… why not curl?
I think most track athletes have a limited amount of time and limited amount of physical resources. Isolating your biceps with curls adds absolutely no benefit to your ultimate goal…to run fast. Most on this forum believe you should spend the least amount of time and physcial resources needed to best prepare yourself. If you’re doing more, or using exercises less suited to you’re overal goal, you’re wasting resouces that could be better spent with more productive training.
