Who knew you could fire up your core in just three minutes? This quick six-move circuit is the perfect add-on to any workout—no equipment needed. It hits all the right spots for better posture, balance, and even helps with lower back pain. Just set a timer and cycle through mountain climbers, dead bugs, bird dogs, alternating leg lowers, Russian twists, and a plank—30 seconds each. Your abs will thank you! #Fitness #CoreWorkout #FitnessHacks
