One of the most simple exercises you can do for your core and abdominal muscles is the standing side body crunch, or as I like to call them, side-to-sides. Workout #5 of my 5 minute fat burning video series does just that – burns your abs with several instructional and easy-to-follow sets of side-to-sides. So if you’re looking to firm your mid-section and reduce your waistline, whether or not you already have a good core & abdominal program, consider adding these 5 minutes of core & abs to your day. Everyday!
