Daily Halacha - Shabbat Laws, 6th of Iyar 5777

Is it forbidden to run on Shabbat?

One's walking on Shabbat should not be like one's walking on weekdays, as it is stated "and honor it by not following your ways." Therefore, one should not run on Shabbat, and one should not jump on Shabbat [Shulchan Aruch 301, and Mishnah Berurah].

Is exercise permitted on Shabbat?

Exercise such as walking or using equipment to strengthen muscles for health or pleasure, if one does not intend to sweat, is technically permissible according to the basic law, but it is proper to be stringent [Responsa of the Rishon LeZion 2, p. 152].
