Need an ab workout with a little cardio twist? Do this sequence once to break up your time spent sitting or repeat it up to 5 times with 30-60 seconds of rest between each repetition.
It’s important whenever you complete ab exercises that you really try to lift your shoulders off of the floor and keep your gaze into your belly button. When you try to use just your neck to do ab work and gaze up at the ceiling throughout a sequence, you put a lot of strain on your neck. Be nice to your neck and let your abs do all the work for you! They may be sore tomorrow, but trust me, ab soreness trumps neck strain any day.
