Feeling dreary? Here is why you have off days at gym

No matter how often you exercise, we all have that weird experience where a routine will feel great one day and horrible the next. There are many factors at play, but The Wall Street Journal lists these as the six most common reasons for an off day:

Sleep: A bad night of sleep can affect workouts for up to 48 hours.

Water: If you don’t get enough water before or after a workout, it can lead to inconsistency in workout.

Drinking alcohol: If you've ever tried to exercise after a night of beers, this is pretty obvious. Drink lots of water and you’ll be back on track.

Boredom: There's a good chance you’ll feel sluggish out of pure boredom. Mix it up and try new exercises.

Eating: Exercising demands a lot of energy, so if you're not eating the right foods, you might feel sluggish because you simply don't have the energy to really work out.
