As runners we are great at moving our body forward in the sagittal plane over LONG periods of time. On top of that, most of us strengthen by performing squats, lunges, bench press, etc. which promotes mostly the sagittal plane of motion. What we don't realize is how much side bending (frontal plane) and rotation (transverse plane) our body goes through while running.
Here is a series of exercises which focus on the frontal and transverse planes of motion we use while running. These exercises have a foundation based on lunges and squats by using our arms to drive motion in other planes of motion. Using our arms as a driver also strengthens the core and upper extremity.
These exercises can be performed prior to a run ( after stretching) for muscular activation. When performed prior to a run, do not use any weights. For strengthening use between 5 - 10 lbs., depending on the exercise. This helps to build muscles in all three planes of motion.
In addition to tri- plane exercises, I perform more traditional strengthening exercises such as squats ( 135 lbs!!), pull ups, power cleans and dead lifts. However, lack of strength and endurance of muscles which control the accessory motions (frontal and transverse plane) contributes to fatigue leading to injuries. Adding tri plane exercises to your strength routine will help reduce fatigue, and as a result, decrease your susceptibility to injury.
These are basic tri-plane exercises but can be made more complex as the athlete becomes familiar with the techniques.
I perform 10 repetitions, typically 3 rounds using 5- 10 lbs.
FORWARD LUNGE WITH OVERHEAD REACH
Yes, this exercise is done in the sagittal plane. However, this exercise is powerful because bringing our arms overhead enhances extension of the core muscles. Lifting our arms overhead also creates an eccentric load through our abdominals which is how it contract while running.
Take a step forward while bringing both arms overhead. This creates extension through the trunk and the hip flexors. To make the exercise more similar the running, bring the same arm overhead as the leg stepping forward ( as shown in the front view). Bringing the same arm overhead will help create a rotational movement in the upper body similar to the arm swinging back.
SIDE LUNGE WITH SIDE REACH
This exercise helps to promote the frontal plane motion which occurs while running. As the leg swings forward our body weight shifts laterally over the front leg. Bringing the arm out to the side drives a rotational motion in the thorax eccentrically loading the abdominals.
Take a side step while bringing the same side arm to the out and behind. ( similar to a throwing motion). Focus on sitting back through the glutes, having your torso shift over your knee and keeping your foot facing forward.
BACKWARDS CROSSOVER LUNGE AND CROSS REACH
This backwards lunge helps to promote gluteal activation in the frontal plane while using the arm to drive upper torso rotation.
Reach backwards and across the stance leg while reaching the same side hand in front of the forward leg.
SPLIT SQUAT WITH CROSS BODY ARM SWING
This exercise focuses on rotation of the trunk and loading the hip in a transverse plane of motion.
Place one leg in front and as you squat down swing the same side arm behind, As you come up swing the arm cross body. Stop the motion with the other hand.
FORWARD LUNGE WITH CROSS BODY REACH
This lunge helps to generate the transverse motion of the core and glutes using the opposite arm as the driver.
As you lunge forward reach opposite arm in front of the knee. As you step back bring arm up and out to the side.
To increase the challenge as you step back, step through so the swing leg is behind the stance leg.
BALANCE WITH TRI-PLANE ARM REACHES
A running training program is complete without balance exercises. Balance on one leg - reach both arms up forward, up backwards, right side, left side, right rotate and left rotate. This represents the different cardinal planes of motion. To increase the difficulty alternate reaching one arm at a time. I recommend switching the balancing leg each time so your arms aren't fatigued when it's ready to switch sides.
PLANKS WITH PELVIC DRIVER
Last but not least planks! I don't perform my planks with a hold. I use my pelvis to drive my body in the 3 planes of motion. Use the pelvis to drive up towards the sky, down towards the ground ( drive with your pelvis, don't let your belly sag), side to side and twist to both sides. To change the exercise and challenge your muscles differently, change the foot position or hand position. I put my feet so they are touching. You can put your feet wide, turn your toes in, hands together, the patterns are endless.
As in all exercise programs, if it hurts don't do it! Consult a professional!
