The proper resistance profile for strengthening external rotation should have less resistance in fully lengthened and fully shortened muscles and more resistance in mid-range lengthed muscles. While bands are great tools, they aren’t so great for strengthening rotator cuffs.

Bands? Chains? The strength curve? How can this data make you a better lifter and athlete.

Accommodating resistance, which is accomplished by training with bands and chains, has the ability to take your training to the next level.
