Great Core Routine
Before our run today we had a stretch clinic to go over some basic streches and core exercises that are essential to preventing injuries while running and to make us more effective runners. I found a great core training program in Runner's World magazine last month that Team USA does to get ready for the marathon, it is simple, easy to learn, and takes about 10 minutes, 3 times a week. I have been doing it for the past 3 weeks and already notice a difference.
There are two phases, base and dynamic. You do the base routine for 4 weeks, and the dynamic after that. Here are video instructions of the 4 base routines to show you how to do them. If you are looking for an easy and attainable way to build your core, give these a try!

Plank/Side Plank
Lie in a push-up position with your forearms on the ground, keeping your body in a straight line, your elbows directly below your shoulders, and your abdominals pulled in (top, right). Hold. Shift to your side, keeping the elbow directly under your shoulder and both feet on the floor, top foot in front. Lift your hips until your body is in a straight line. For all variations, start with 30 seconds, build to 2.5 minutes.
PHASE TWO
Hold plank as you have been, but lower and lift into a side plank for four sets of six reps, holding each rep for a count of four. The plank was originally used to test lower-back strength, says Kline, and if you can hold it for two-plus minutes, your likelihood of having lower-back problems is low.
PAYOFF
Develops abdominal and lower-back muscles that support and stabilize the middle of your body.
Bird Dog (My favorite)
Start on your hands and knees, back flat. Raise an opposite leg and arm to hip and torso height. Hold for 10 seconds, build to 30.
PHASE TWO
Perform four sets of six reps, with each side, holding each rep for a count of two.
PAYOFF
Strengthens the muscles along the spine, the upper back, and the glutes.
Back Extension (this can be done at home while rolling a mat on the floor and holding)
Start face down on a Roman chair with your legs hooked and lift your torso up until it's parallel to the ground; your back should be straight, not arched. Hold. Start with 45 seconds, build to three minutes. (The focus is on muscular endurance, not pure strength, so don't add additional weight.)
PHASE TWO
Do four sets of six reps.
PAYOFF
Improves strength and muscular endurance of the erector spinae and other back extensors.
Swiss Hip Extension (can be challenging at first, but don't be discouraged!)
Swiss Hip Extension
Start sitting upright on a stability ball, then walk your legs forward so the ball travels up your spine until it reaches your shoulder blades. With your arms extended out to the sides, lift your hips up until your torso is parallel to the floor. Then lift one knee about 45 degrees, lower it, then lower hips toward the floor, and repeat on the other side for one set. "Don't be frustrated if you can't do this well at first," says Kline. Do three sets of five to seven reps, with two minutes rest between sets.
PHASE TWO
Same as above.
PAYOFF
Mimics the running motion, but on an instable surface (the ball), engaging the hip flexors (psoas, iliacus) and extensors (the glutes) to work together with the abs and back to stabilize the body
