Warning: You may need a tissue or two when watching this mother and daughter completely crush their weight-loss challenge.
The video is one of the many inspiring installments in GiveIt100, a campaign that invites beginners and experts alike to practice anything—from making healthier choices to learning killer dance moves—for 100 days. Participants record their progress on video so that by the end of the challenge, they have glorious visual proof of how far they've come. And for this mom and daugther, the strides they were able to make side-by-side are what have encouraged them to keep going—for even more than 100 days (hence the tears).
What healthier choice would you make if you knew you only had to do it for 100 days? Let us know in the comments, or tweet us @greatist.
