Introducing the smallest of our strength training aids - The Bison Grips Stumpy's! Used as a pair, these 'coke can' sized holds are perfect for climbers who are just starting their training journey. Hang them over beams, bars or branches and preform exercises such as; Pull ups, dead hangs and lock offs. Our Stumpy's are also a great warm up aid at the crag, and being so small you can throw them in your day sack and not think twice. With 65mm of girth, its gives you a similar feel to a pull up bar - yet softer on your skin!
