IronMind Eagle Loops transform basic exercises into finger-strengthening moves par excellence: hitch Eagle Loops over a chinning bar for pull-ups, or connect them to a bar, loading pin or pulleys for deadlifts, rows, static holds and more. You can even hook them up to your sled. Designed to train any combination of fingers, except the thumbs, Eagle Loops might be the missing link in your grip training routine. Eagle Loops are perfect whether you're interested in boosting your 1-RM open-hand strength or want to increase your open-hand stamina.
