So grab your sister, brother friend or mate, and we'll show you how to get started.
"Any time when you can add a little competition into something, it motivates you," said Adam Bornstein, editorial director of Livestrong.com. "When you have a partner, especially say if it's a significant other or a friend, if they're doing a little bit better than you or moving faster, doing more reps, you want to keep up."
And no gym is required. Bornstein said the best exercises, like squats, lunges and pushups, don't require equipment - a very economical and practical way to go.
"The best way to go is with body weight exercises. It's the safest way. Everyone can do them, and they were proven to be effective," said Bornstein.
Trainers will tell you the single most effective reason why you want to buddy up is accountability.
"What partnering up does, is it gives you that accountability that helps you stay motivated so you can finish your workouts and do them and stay consistent until you see results," Bornstein said.
"I find that when she's with me, I always push myself a little bit harder," said Chris Newton of Redondo Beach.
Newton has to work extra hard, because his wife, Kate, is a dance instructor. But like most humans, she needs a nudge now and again.
"He'll motivate me to get off the couch. You know, I just want to sit there. I just taught for eight hours. And then once I am up, I'm so competitive that I just want to kick his butt," Kate Newton said.
Remember to think outside the box when it comes to your workout routine.
"Side plank is a great way to work your abs, but what's going to happen here is you're adding a little bit of a dynamic movement, so you're working your arms, you're working your back, while also working your abs," said Bornstein.
As the old saying goes, "no pain, no gain." So make sure you feel the burn.
"They say all the time that whatever you're doing, if you like it, do exactly the opposite because it's probably what your body needs the most," Bornstein said.
