Ab workouts do not always have to be done lying down on a mat. Exercises where you are standing place less of a strain on the neck and are just as effective, improving strength and stability.
Start by holding a dumbbell in both hands above your head and left shoulder, pointing your right foot out to the side. Hold your abs in – always to protect your lower back, then in one movement draw your elbows down as you bend your knee into your chest. Return to start position and repeat 12-16 reps 2-3 sets.
