The more promising avenue may be employers. Ms. Royer hopes to later demonstrate not just that commitment contracts work to get employees to the gym, but also that they save employers enough through improved health to be worth paying for.

更靠谱的途径可能在于雇主。罗耶随后希望证明，承诺合约不仅可以颇有成效地促使雇员去健身房，还可以通过改善员工的健康，为雇主省下足够多的钱，从而让雇主的投入物有所值。

For now, you can use a service like Stickk to set up your own commitment contract: Promise to go to the gym, and set aside money that will be given to charity if you don’t. For extra incentive, you can even use an anti-charity: If you don’t work out, your money will be given to a cause you hate. That’s more likely to keep you working out through beach season than simply paying up front for a gym membership.

目前，你可以用Stickk等服务制定自己的承诺合约：承诺去健身房，并留出一些钱，如果不去便捐给慈善机构。如果需要额外的激励，你甚至可以利用自己不喜欢的机构：如果不锻炼，你的钱就会捐给你讨厌的某项事业。和预先花钱办健身房会员卡相比，这种做法更有可能让你在整个去沙滩游玩的季节坚持锻炼。
