2 surprising moves that could prevent back problems

On this Fit Life, if you're worried about lower back problems you might want to focus on something surprising, your abs. KY3's Paul Adler visited with Zach Dudenhoeffer of 10 Fitness to learn about 2 exercises to potentially help you out.

On the first one, we're using a medicine ball to do what's called a Russian Twist. Bodybuilding.com explains the Russian Twist this way, "Lie down on the floor placing your feet either under something that will not move or by having a partner hold them. Your legs should be bent at the knees. Elevate your upper body so that it creates an imaginary V-shape with your thighs ." See Paul's video for examples.

Zach recommends 2 sets of 20.

The second exercise is a standard plank. WomensHealth.com explains the plank this way, "Start on the floor on your hands and knees. Lower your forearms to the floor with elbows positioned under your shoulders and your hands shoulder-width apart. If someone looked at you from the side, your arms would form a 90-degree angle. Step your feet back, one at a time. Maintain a straight line from heels through the top of your head, looking down at the floor, with gaze slightly in front of your face. Now, tighten your abs and hold."

Zach recommends holding the plank for 1-2 minutes for 2-3 sets.

As always, you should consult a doctor before starting any exercise program.
