Crunches are out, standing abs are in! Certified trainer Britany Williams says ditch the floor and grab some dumbbells for a core workout that actually mimics real life. Moves like overhead marches, windmills, and standing ab chops not only spice things up but also help with balance, posture, and even carrying your groceries. Plus, you can easily level up by adding more weight. Who knew working your core could be this fun (and not require lying on the floor)? #Fitness #FitnessHacks #CoreWorkout
