Struggling to Find Motivation to Work Out? These Apps Can Help

Charity Miles is an app that helps you track your walking, running, or biking distances — and it shows you how much money your exercise is accumulating for charity! Similarly to marathons and 5Ks, you can ask people to pledge for your cause. The amount of money that you can earn for charities is unlimited, and you don't have to be running a specific race to have sponsors; you can be earning every single day, just from your morning run.
