BOSTON ( TheStreet) -- Summer's here.Which means it's time to admit to yourself that most of your New Year's resolutions went by the wayside sometime around Groundhog Day. Here's a look at some of the most popular resolutions that Americans haven't kept -- financial and otherwise -- and the money they're wasting. We resolved to work out more Thanks in large part to suckers who joined a gym in January, the fitness-club industry garnered revenue of $24 billion in 2009, and it's expected to keep growing over the next five years, according to market-research firm IBISWorld. Some 45.5 million Americans belong to a health club, according to the International Health, Racquet and Sports Club Association. But the association also reports that members go to their gyms only 101 days a year. Factor in the gym nuts who work out twice a day and you're left with a whole lot of people who join a gym and never go. If you've pretty much quit working out, consider benching the membership. While many gyms charge hefty fees for canceling the membership entirely, some allow members to put their memberships on hold temporarily, especially in the event of an illness or job loss. We resolved to lose weight It would seem logical that eating less food would result in spending less money. Yet the weight-loss services industry booked revenue of $3.9 billion in 2009, led by the likes of Weight Watchers International ( WTW) (with 18.7% of the market) and NutriSystem ( NTRI) (14.6%), according to IBISWorld. Meanwhile, two-thirds of Americans are overweight and nearly a third are obese, according to the National Center for Health Statistics. Don't give up the fight. But if your monthly fee for an online weight-loss service hasn't yielded results in the past six months, maybe it's time to consider that eating a branded frozen dinner, while logging calories on a computer, might not be as effective as taking a long walk with a carrot. We resolved to quit smoking By now, we know that the surgeon general has determined that smoking is bad for your health, but the tobacco industry still produces revenue in excess of $1.5 billion, according to IBISWorld. Philip Morris' ( PM) Marlboro remains the market leader, with sales greater than its five leading competitors combined, according to the Centers for Disease Control. If you tried -- and failed -- to quit smoking in the first half of 2010, you may want to try again in the second half, especially if you're a New Yorker. First, the Family Smoking Prevention and Tobacco Control Act, signed into law a year ago, finally went into effect last week. Cigarette companies are now required to cover half of the front and rear of each pack with warning labels, making the health risks harder to ignore. Second, the New York legislature just passed a law that adds $1.60 in state taxes to every pack of cigarettes. The law, which goes into effect July 1, will push the average price of a pack to $9.20 -- and close to $11 a pack in New York City, which adds its own tax, according to the New York Times. For two-pack-a-day Manhattan dwellers, that adds up to $8,030 a year for cigarettes. Do the math, keep that resolution and get out of debt.
