Time to work the abs and core! V-ups are an intermediate to advanced exercise but can be modified for beginners by doing only arms or legs independently. Also known as a jacknife situp, this ab/core exercise will burn baby burn! Click here for a video and explanation of the exercise on Bodybuilding.com. For the really advanced, add a medicine ball pass (see photo) to increase the intensity.
THE CHALLENGE: Do three sets of 10-15 reps, 3 times in the next week. Ready, set…V-UP!
