If your New Year’s resolution is to lose weight, here’s something that may add extra motivation.

This video captures LaKeisha Shurn, as she goes to the gym for 100 days in a dogged attempt to lose weight.

Whatever she did worked – Shurn dropped 18 pounds in the 100 days and more than 50 in the last year.

It's pretty amazing stuff and quite a victory for Shurn, who is also battling some emotional issues.
