By doing physical exercise, here I'm writing about relatively intense exercise, like running, doing strength exercises like push ups, doing sports, a martial art, and so on, one will be strengthening one's Mangala (Mars) and Venus (Shukra). Here I'm not writing about low effort level exercises, like walking.
So to do this it will strengthen Mangala (Mars) because doing physical exercise is the realm of him. Mangala (Mars) is about war, competition, physical strength, etc. One strengthens Shukra (Venus) because by doing exercise one will be beautifying one's body, because this is a result of exercising, this will happen especially if one is also careful with one's diet and also takes care of the beauty of one's body. So beauty is the realm of Shukra (Venus).
The astrological benefits of this is that it will help to delay aging, one's confidence will increase, one's courage and strength will also increase. One will become more difficult to defeat. One's mental strength will also increase.
This will also help in one's beauty, one's facial features might become more beautiful or not degenerate so much with age. One will attract romantic love. If one is married this will benefit the marriage. It one is a man and is single, the chances will increase for him to get a beautiful partner.
