Two-Handed Bowling Technique Explained

Two-handed bowling is a ten-pin bowling style in which the bowler uses both hands to control the ball through the swing but takes the thumb out of the ball entirely, releasing off the fingers only. Removing the thumb frees the wrist and fingers to impart far more revolutions on the ball, which produces a bigger, sharper hook and more powerful pin action than most one-handed deliveries.

Once seen as a gimmick, the two-handed style is now a legitimate, tour-winning technique, thanks largely to professionals like Australia’s Jason Belmonte, who used it to win multiple major titles. It is fully legal under United States Bowling Congress (USBC) rules. Here is exactly how the technique works, what makes it so powerful, and how to start learning it.

How the technique works

Despite the name, two-handed bowling is not about throwing the ball with two hands at the moment of release. The bowling hand does the actual delivering; the non-bowling hand is a guide and support. The sequence looks like this:

1. Setup and grip. The ball rests in the fingers of the bowling hand with the thumb out of the ball. The opposite hand cups the ball for support.
2. Backswing. The non-bowling hand steadies and helps lift the ball into the backswing, taking weight off the bowling arm and shoulder.
3. Downswing. As the ball comes down, the support hand stays with it, keeping it stable and behind the wrist.
4. Release. Just before the ball reaches the bottom, the support hand comes off, and the fingers of the bowling hand roll up the back of the ball, imparting heavy revolutions.

Because there is no thumb to clear, the fingers stay in the ball longer and lift more aggressively, which is where the extra revolutions, and the big hook, come from.

Why it creates so much hook

The amount a ball hooks depends heavily on its rev rate, the number of revolutions it makes travelling down the lane. A thumb-in, one-handed release has to time the thumb exiting the ball cleanly, which naturally limits how much the fingers can load. With no thumb, a two-hander’s fingers do all the work and can generate a very high rev rate, so the ball stores energy and then hooks hard into the pocket. That aggressive entry angle is what makes pins scatter so violently.

For a deeper look at why a hooking ball strikes more often than a straight one, our guide to how to hook a bowling ball covers the physics that two-handers exploit to the extreme.

The pros and cons

The style is powerful, but it is not free of trade-offs. Weighing them honestly helps decide whether to try it.

Factor	Two-handed	Traditional one-handed
Revolution potential	Very high	Moderate to high
Hook / entry angle	Large, aggressive	Controllable, generally smaller
Physical demand	High (core, balance, legs)	Lower
Accuracy learning curve	Steeper early on	More forgiving to start
Wrist/thumb strain	Less thumb strain	Thumb fit is critical
Equipment	Drilled without a thumb hole	Standard thumb + finger holes

The headline trade is power for effort and precision. Two-handers can create huge hook, but they need more athleticism to repeat their delivery, and it takes real practice to control all that extra movement accurately.

Equipment differences

A two-handed bowler’s ball is typically drilled with just the two finger holes and no thumb hole (or a balance hole where the thumb would go, subject to current specifications). Because the thumb is not inserted, the fit and layout are built around finger positioning and the desired reaction. If you are experimenting, a coach or pro-shop fitter can set up a ball that suits a no-thumb release rather than converting a standard one-handed layout. Choosing the right specification matters just as much here as it does when picking what weight bowling ball to use.

How to start learning it

Two-handed bowling rewards patience. A sensible progression:

• Build the base. Work on balance, posture and a stable slide; the extra revs demand a solid platform.
• Learn the finger release. Practice rolling off the fingers with the thumb out, feeling the hand stay behind and under the ball.
• Add the support hand. Introduce the non-bowling hand only once the release feels natural, so it guides rather than throws.
• Start slow, build speed. Accuracy first; power second. Many new two-handers over-hook and spray the ball early on.
• Get coached and fitted. A USBC-certified coach and a proper ball fit shorten the curve dramatically.

Remember that the lane itself matters too, oil patterns and lane dimensions shape how much a heavy hook actually helps, as our overview of bowling lane dimensions explains.

The bottom line

Two-handed bowling trades a bit of simplicity for a lot of power. By removing the thumb and using the off-hand as a guide, bowlers unlock revolution rates and hook that are hard to match with a traditional release, which is why the style now wins at the highest levels of the sport. It asks for more athleticism and more practice to control, but for players chasing maximum pin action, it is a proven, fully legal way to bowl.
