To supercharge your core (and make the traditional side plank even more powerful) try the rotational plank from SELF’s Best Bodies Challenge. This toning exercise engages your obliques, the muscles that run along the sides of your waist, explains Los Angeles-based trainer Astrid Swan.
The key to mastering the move is to keep your abs tight and hips driving up (no sinking to the floor!). Watch Astrid demo the move below:
Start in side plank with left forearm on floor and right arm extended to ceiling. Keeping hips lifted, rotate torso, bringing right arm under body then twist back to neutral. That’s 1 rep. Do as many reps as possible for 45 seconds, then switch sides.
The mega-toner is part of SELF’s Best Bodies Challenge Best-Ever Abs Workout. (And with a name like that you know the rest of the moves are just as good as this souped-up side plank). Score the rest of the routine—plus six additional free workouts and seven days of heathly recipes—by signing up here. Abs, activated.
