If your patients have trouble sleeping after an evening workout, offer them these tips from Shape Magazine.

Go Low-Impact
Save your truly heart-pounding workouts for the days when you have more free time in the morning, and use your evening exercise slots for less-intense options, like a walk or super-easy run or—even better—vinyasa yoga. In fact, no matter what you do, consider ending nighttime workouts with a few poses, like Happy Baby or Corpse pose. The soothing movements and focus on breath will help you wind down, preparing you for bed.
