LASER Isolation Drills. Step-By-Step Explosive Core Power Drill Checklist

LASER Drill Basics

Isolating Explosive Core Power

The following Isolation Drill checklist covers the basics of LASER drills to isolate and improve explosive core power on deeper contact zones. We recommend to minimize your stride when training LASER Blast or LASER Whip drills for the first time as to reduce the influence of the extremity muscle groups (arms and legs) so you can focus on swinging with your core. If your’e not keen on the idea of a short stride you can train LASER drills with a bigger/longer stride if you choose.

Step 1

Back foot pointing straight

If the back foot is open it takes longer to rotate to the baseball and may result in being late with your swing.

Step 2

Stride out a few inches past shoulder width

Stride out to shoulder width apart


Isolate the foot down position and to help with balance. If you’re too narrow with your stance you’ll fall off-balance when you swing.

Step 3

Make sure your front foot is pointing straight

If you start with your front foot open you’ll land with your front foot open and pull off the ball, especially on the outside pitch.

Step 4

Take the weight on the inside balls of your feet and lean slightly forward (get off you heels). Imagine you’re squeezing a big stabilizing ball between your knees


Helps you to stay short and balanced with your stride, prevents lunging and improves power. This movement engages your core via your groin muscles, as opposed to bending over your knees forward, resulting in your legs taking the weight as you disconnect from your powerful core muscles.

Step 5

Relieve upper body tension. Begin with your back elbow down, relax your upper body and focus on seeing the ball


Reducing upper body tension and minimizing movement will improve your powerful core swing. By focusing on the ball you’ll avoid over-thinking and invoke your natural reactive swing.

Step 6

To begin your swing pick up your front foot and turn you knee in. To keep your shoulders square tilt your front shoulder toward the ground

Improves power by initiating internal rotation of your hips as your knee turns in to your center axis. Lifting and turning your front foot of the ground (lateral hip rotation) can trigger a dip in your back shoulder and wrapping (turning your shoulders too much). To prevent this you can work on a counter-balance movement to keep your shoulders on a level plane, in this case tilting your front shoulder toward the ground.

Step 7

Load against your back leg as opposed to loading your all your weight back toward your back leg.

Loading against your back leg


Loading against your back leg keeps your core engaged with your swing, helps you to stay centered and stay back. Loading with your weight on your back leg will reduce bat speed and increases the likelihood of jumping out at the baseball, dipping the back shoulder and spinning off the ball.

Step 8

Hips rotate first and your hands stay back until you decide to swing

Hips rotate first - hands stay back


Leading your swing with your hips as opposed to leading with your hands will improve bat speed, power and allow you to hold up on your swing at the very last moment. This also prevents drifting with your hands and dragging the bat through the zone.

Step 9

Allow the ball to travel before committing to your swing

Allow the ball to travel


Letting the ball travel will improve bat speed and power, prevent lunging, casting and give you a better batter’s eye.

Step 10

Spin on your toes by rotating your back foot from your core (back hip joint) as opposed to rotating your back foot from your knee

Spinning on your back toe when hitting


The faster your back foot rotation the faster your swing. Rotating from your core (back hip) will improve bat speed and power.  If you turn your back foot from your back knee it’s physically impossible to spin on your toes and you’ll reduce bat speed.

Step 11

Stay Connected with your swing. Hands inside the baseball and head down at contact

Staying connected with your swing


The scientific definition of “hands-inside-the-baseball” is keeping your back arm close to your torso during your swing. It’s vital your back elbow stays as close to your hips (core) until you decide to commit to your contact zone (the spot where the bat meets the ball). Failure to stay connected with your back elbow, as it rotates around your axis results in a “long swing” and you’ll lose bat speed & power. This is commonly referred to as reaching or casting.

The Laser Strap Bat Speed Trainer helps you to stay connected during your swing. Functional resistance binds your back elbow to your core, along with an extra boost in bat speed as the main elastic strap accelerates your bat through the zone, training your body and mind to swing a quick bat.

Step 12

Both arms strapped drills. Higher and deeper contact zones avoid lifting on the follow through and keep 2 hands on the bat all the way.

How To Get More Bat Speed


Hitting a high pitch with a flat bat plane will lift the ball for you, therefore you don’t need to lift on your follow through. Lifting on your follow through with the high and deep contact zone will knock your head off the ball, cause you to fall off-balance as you over-rotate on your back foot and fight against your natural swing path. Releasing your top-hand from your swing will also fight your natural swing path, as a result you’ll fail to hit the up-and-inside pitch effectively.

Step 13

Back arm strapped drills. Lower and extended contact zones release your top-hand when you feel pressure on your back shoulder.

Low and away opposite field hitting


Hitting a low and extended pitch and releasing your top-hand will allow to you stay through the ball and hit the low ball for power. Keeping two hands on the bat will result in pulling off the ball as your top-hand fights against your natural swing path causing you to roll over on the ball.
