"This abdominal exercise is excellent for several reasons: It is an extremely functional exercise, it works your entire core region, front and back, while sculpting great-looking abs at the same time," says Tom Holland, an exercise physiologist and author of Beat the Gym: Personal Trainer Secrets Without the Personal Trainer Price Tag.
To do it: Assume a push up position, making sure your body forms a straight line from your shoulders down to your toes. Raise your right hand and left leg out to form a straight line with your body, hold for two counts, then return to plank position and repeat with the other arm and leg. That’s one rep. Holland recommends doing 2-3 sets of 10-20 reps, several times per week for best results.
