Everyone knows college is tough. My professer suggested to me that I should daily do some strenous exercise for at least half an hour. I think he gave that suggestions, so that I could reduce my stress level and after exercise my brain will be fresh so I could study better. I on the other hand don't exercise at all (not because I hate exercise or due to a lack of options) but because I think those 30 minutes are better used studying. So my question is this: Will 30 minutes of strenous exercise daily have a significant beneficial effect on my studies or not? Thoughts?
