If you have days where you lack the energy to work out, you’re not alone. Life is busy and everyone gets tired. But if you skip your workout every time you feel tired, you’ll never get off the couch. Plus, regular workouts help boost your energy. So, it’s better to do something, no matter how small, than nothing at all. Even short stints of activity help keep you moving towards your goal. On days when you’re low on energy, take just a 5-minute walk, or stretch during TV commercials, or take the stairs instead of the elevator.
