If the cold, dark weather is keeping you from working out, one fitness trainer has some motivating tips.

“If you work out, it’s a mood booster, so not only will you make yourself look good, but you’ll feel better,” said Niki Glor, a trainer at Crunch in New York City.

Tip 1: Work out with a friend – It’s much more fun to work out with a friend then alone.
“Make play dates with buddies, so instead of going to a movie, go to a yoga class together," Glor said. And, some gyms offer complimentary sessions with your membership with a trainer.

Tip 2: Get a trainer
It’s harder to let someone else down, then it is to let yourself down, Glor said. So if you have a trainer – you won’t be likely to cancel on them.

Tip 3: Put on your sneakers and go
“Put it on, and before you know it, you are going to be like, ‘Well, I’m already dressed, I might as well go,’” Glor said.

Tip 4: Don’t watch the clock
“My trick, and what I tell my classes, is we're just gong to work out for 15 minutes. After 15 minutes if you don't feel like it, go home,” Glor said. “Most of the time when you are there, you're blood gets flowing and you want to stay for half hour,  45 minutes or a full hour."

Tip 5: Multitask
No matter the season – everyone’s biggest excuse is finding time to work out.  Glor’s tip? Do two conditioning moves at once and cut your work out in half.
