The YY Elastic Bands are training and resistance bands which allow you to strengthen and stretch your muscles, and increase your flexibility. Made of high quality silicone, and with 5 different weight resistance options these bands are perfect for training, stretching or warming up before a session. Research shows that strength gains from using resistance bands are similar to training with dumbbells - but with the added benefit of being able to easily transport them. Perfect for packing in your crag bag for every day sessions, or to take away on foreign trips. (Sold separately).
