On those days you second guess yourself for setting a 6am alarm to hit the gym, or skip happy hour in favor of a run, come up with and recite your own fitness personal mantra. Since it’ll be based on your own ideals and values, it’s a powerful reminder to keep you motivated.
A mantra is a sacred word, phrase, sound, or a group of words in Sanskrit that is normally used in meditation and spiritual activities. It doesn’t need to make literary sense, but it’s often spiritually and personally meaningful.
