“Any Torah scholar who is not as hard as iron, he is not a Torah scholar.” - Ta’anit 4a
In his classic work, “Orot,” Rabbi Kook writes that the exercise of young Jews in Eretz Yisrael, in order to strengthen their bodies to become mighty sons to the nation, adds overall strength to the Jewish People, which enables the righteous to bring more Divine light into the world.
There are not a lot of Jewish specific strength programs out there, but "Who is wise? He who learns from every man." - Pirkei Avot 4:1
