Pennsylvania’s Ringing Rocks Park is packed with boulders which create a unique sound when struck with a hammer. The percussionists of Square Peg Round Hole decided to use the park to record an original song using only rocks and hammers as their instruments.
Work out like a caveman with these prehistoric style dumbbells, kettlebells, ropebells, clubbells, and gripbells made from hunks of granite. Their handles are made from Finnish birch wood. (Thanks Kema!)
