Holiday chaos got your workouts on pause? This 24-minute dumbbell circuit from trainer Joe Bronston is a total upper-body game-changer. Just two dumbbells, six moves, and barely any rest—your biceps, triceps, chest, back, and shoulders get hit hard. No gym, no problem—just grab a mat or towel for floor moves. Do each exercise for 40 seconds, rest 20, repeat the circuit 2-3 times. Quick, sweaty, and you’ll feel it the next day! #Fitness #FitnessHacks #QuickWorkout
