How much should it cost you to work out?

How much do you spend per year on, say, a gym membership, your own exercise equipment, a personal trainer, or your favorite yoga class?

Once you have a number, think about how that amount compares with what your friends spend. If, for example, your buddy pays $1,000 per year and you pay only $100 per year, you might assume that your approach is smarter.

But hang on. If your friend works out 365 days a year (yes, really), and you break a sweat just once a month, take a closer look at your "cost-per-workout." For you, it's $100/12 or $8.33. For your pal, it's $1,000/365 or $2.74.

To find out if your cost-per-workout is worth it, ask yourself two questions, says Rachel Sanborn, a certified financial planner at LearnVest Planning Services. "Does my routine get me moving? Can I afford it?"

If you're paying a lot, but you can afford it and you're seeing great results, it's worth it. But if you're struggling to pay the bills and you're not working out often, try a new exercise strategy.

"To cut back, get rid of any fixed costs, such as a monthly gym membership fee. Then do free workouts — follow routines on YouTube or Hulu, rent fitness DVDs from the library, or walk or run outside. If that's not enough, make a small, one-time purchase that'll help you get in shape. For instance, buy a $20 kettlebell, as opposed to an expensive rowing machine," says Sanborn.

To get an idea of where your spending habits fall, we asked 10 real people to share their cost-per-workout. Meet the woman who does yoga three times a week — and pays six cents per workout — and the guy who spends $15,649 a year on fitness. (And see how he's lost 20 pounds doing it ...)
