Core for Christmas Challenge!! There is exactly 5 weeks until Christmas! So instead of summer abs we are going to get Christmas abs! This week we are starting easy with 5 mins of core with 5 exercises each lasting 30 seconds with 30 seconds rest in between each exercise! ( for more challenge double it) To Enter the challenge 1) Post a video or picture of you doing the core on your story or posts. 2) Tag me and hashtag #coreforchristmas For every week you do it your name will get put in, so if you do all five weeks you will get entered 5 times! I will pick two winners to get a Nike/Xendurance Christmas present! #core #coreworkout #abs #workout #training #fitnessmotivation
