Dead Bug For Runners
This exercise will improve core stability.
Lie on your back with your legs and arms off the floor. Keep your ribs down and low back close to the floor. Brace your abs and form a 90-degree angle at your hips, knees and shoulders — pretend you’re a bug, dead on its back. Next, move your legs and arms slowly in the air as if you’re running. Keep your low back from arching off the ground. Perform three sets of 60 seconds.
