Two moves, two weeks: You got this! Every day you'll do either a forearm plank or a glute bridge hold for a set amount of time, starting with 30 seconds and working your way up to a full minute, with a daily email — featuring advice from personal trainer Rob Sulaver, C.S.C.S., founder of Bandana Training — to guide you through each exercise. You'll strengthen your butt and core while getting into the habit of doing something physical every day — it's a win-win!
