Though gutting it out to the end of a workout may feel demanding, reaching your destination requires going the distance. Overcome physical humps with these tips:

• Chant persistence: Repetition drives momentum, so if the last mile taxes your spirit, recite short mantras in rhythm with each step and breath: “I’m almost there — I’m closer now — I’m almost there — I’m closer now.” Keep focused on the words and cadence. Think The Little Engine That Could.

• Inject melody: Studies show that working out to music can hustle you over hurdles. But you don’t need headphones. Research shows that just thinking about a song can cue emotional triggers. So crank up the volume on your mental boom box and call to mind favorites for personal significance or popular inspiration. Try the Chariots of Fire and Rocky theme songs, or the Olympic fanfare.

• Reward progress: Sometimes a dangling carrot can encourage tenacity. Think of that cold glass of tea or refreshing shower that awaits after your jog, or the delicious healthy dinner you promised yourself for doing that last lap in the pool.
