The New Science of Throwing Faster: 5 Proven Drills for Junior Pitchers (Backed by Coaches)

If you’ve ever watched a baseball game and thought, “How do those pitchers throw so fast?” — you’re not alone. Every young pitcher dreams of firing that baseball past the batter with blazing speed. The good news? It’s not just about strength anymore. Thanks to new research and smarter training, we now know that throwing faster is a mix of science, mechanics, and a few key drills. 

Let’s break it down in a simple way, so even junior pitchers (and their parents or coaches) can understand how to boost throwing velocity — the smart way. 

The Science Behind Throwing Fast 

Throwing a baseball isn’t just an arm movement — it’s a whole-body motion. When you pitch, energy starts from your legs, travels through your hips, and flows up your torso before exploding through your arm. 

Think of it like cracking a whip — the handle (your legs and core) starts the motion, and the tip (your hand and the ball) releases that energy at top speed. 

Modern coaches now use biomechanics and slow-motion video to study how top pitchers move. The goal isn’t to throw harder but to throw smarter — using your entire body efficiently to reduce stress on your arm while increasing speed. 

Why Old-School Training Doesn’t Work Anymore 

In the past, pitchers were told to “just throw more” to get faster. The problem? That often leads to overuse injuries. 

Now, coaches use science-backed drills that improve movement, coordination, and strength — all while keeping players healthy. These drills don’t just make you throw faster; they make you throw better. 

The Top Five Proven Drills for Junior Pitchers 

Below are five coach-approved, science-based drills to help junior pitchers build velocity safely. 

Let’s look closer at each one. 

Pivot Pickoff Drill 

This one is a favorite among pitching coaches. Stand sideways like you’re pitching, lift your leg, then rotate your hips and throw the ball — but only using your lower half and upper torso. 

It teaches your body to generate separation between your hips and shoulders — the secret to speed. The more your hips lead, the faster your arm can whip through. 

Long Toss 

Long toss isn’t just about throwing as far as you can. It’s about feeling your body move naturally and smoothly through each throw. 

Start short and gradually move farther back with each toss. You’ll strengthen your arm and learn how to use your legs and core for power. 

Just remember: form matters more than distance. 

Towel Drill 

This classic drill might look funny, but it works wonders. Instead of a ball, use a towel and snap it toward an imaginary target. 

Why a towel? It forces you to focus on mechanics — your stride, your follow-through, and your release point — without the pressure of throwing a ball. 

Bonus: it’s easy to do indoors! 

Med Ball Rotation 

Grab a medicine ball (or even a basketball if that’s all you have) and stand sideways. Rotate your hips and throw the ball against a wall or to a partner. 

This drill builds explosive core rotation, which is where much of your throwing power comes from. 

Think of your core as the engine — the stronger and quicker it turns, the more power your arm gets. 

Reverse Throws 

This one’s a hidden gem for keeping arms healthy. Hold a light ball or resistance band, and throw it backward — as if you’re rewinding your throwing motion. 

It strengthens the small stabilizing muscles in your shoulder that protect your arm from injuries. Coaches love this drill because it builds durability — the kind that keeps pitchers in the game all season long. 

Putting It All Together 

Doing these drills once won’t magically make you throw 10 mph faster. But practicing them regularly, with good form, will build real results. 

Here’s a simple weekly plan to start: 

Remember, your goal isn’t just speed — it’s efficiency. When your mechanics improve, the speed naturally follows. 

Tips from Real Coaches 

• Warm up first: Never throw cold. Always stretch and do light throws first. 

• Record yourself: Watching your motion helps fix small mistakes. 

• Don’t overtrain: More is not always better. Listen to your body. 

• Stay patient: Building velocity takes time — even the pros work on it constantly. 

The Bottom Line 

Throwing faster isn’t magic — it’s science, practice, and patience. With the right drills and smart coaching, any junior pitcher can increase velocity safely while improving control and confidence. 

So next time you pick up a ball, remember — you’re not just throwing; you’re unlocking a chain reaction of power from the ground up. 

Train smart, throw fast, and most importantly — have fun doing it.
