60 Seconds of Oblique V-Crunches Follow the instructions below to really target those obliques, doing as many reps as you can for 30 seconds before switching sides. Lie on your right side, with your left hand behind your head and your right hand on the floor. Press down into your right hand as you raise your straight legs off the floor, bringing your torso toward your legs. Lower yourself back to the floor with control. This completes one rep. Do as many reps as you can in 30 seconds, then repeat on the other side. Image Source: POPSUGAR Photography
