Key takeaways

The ProSendr Widener is a training aid that straps to the lead arm and presses a curved "U"-shaped bar against the lead shoulder.
It was designed by GOLF Top 100 Teachers David Woods and Sean Foley to widen the swing arc and encourage external rotation of the trail arm.
Wyndham Clark has used the Widener with every club in his bag, including the driver, during a stretch of three wins in four months.
That run includes his second U.S. Open title and last week's BMW Championship victory.

A training aid called the ProSendr Widener has become a regular sight in Wyndham Clark's practice sessions this year, during a stretch that has made him one of the hottest players on the PGA Tour.

What is the ProSendr Widener?

The Widener attaches to the golfer's lead arm with a strap positioned just above the wrist. From there, a curved arm extends into a "U" shape that presses against the lead shoulder, with enough range of motion to allow the hands to move above the head. The design is meant to create width in the swing by pushing the hands away from the body — a longer arc in the full swing, and a shallower one in the short game.

An S-curve in the shape lets the trail arm rest against the club normally while encouraging that arm to rotate externally, which is intended to add stability through the swing. The device was created by David Woods and Sean Foley, both members of GOLF's Top 100 Teachers.

How has Wyndham Clark used it?

Clark has been seen working with the Widener across his full bag, from wedges to driver, throughout a run that includes three PGA Tour victories over the past four months — his second U.S. Open title among them, plus last week's BMW Championship.

A wider arc keeps the hands the same distance from the body throughout the swing, which is the mechanism the Widener is built to reinforce.

Reviewers who have tried the device say the fixed width helps stabilize the low point of the swing, particularly on shots around the green where a consistent strike matters most.

Frequently asked questions

What does the ProSendr Widener do?

It straps to the lead arm and shoulder to keep the arms a fixed width apart during the swing, which is designed to create a wider, more consistent arc in both the full swing and the short game.
