Side-delt burn that builds all the way up.
Lead with your elbow and pour the pinky slightly higher than the thumb.
Standing on a band and raising your arm out to the side loads the lateral delt against resistance that peaks right at shoulder height, the exact spot where the muscle earns its keep. That rising tension means the top of every rep demands a genuine fight, no coasting through the finish, and the band punishes any hip bump or shrug by simply not moving. It is the accessible route to wider shoulders, with the slight pinky-high tilt keeping the side delt, not the front, in charge.
They load the movement differently and both grow side delts. Dumbbells are hardest through the middle of the raise, the band is hardest at shoulder height where the delt is working most, many lifters find the band version easier to feel in the right place.
To shoulder height and no higher. Beyond that, the traps take over and the shoulder gets cranky, finish at parallel with a brief fight against the band, then lower slow.
Leading with the elbow keeps the upper arm doing the raising and stops the movement becoming a hand-flick. Combined with the pinky tilting slightly higher than the thumb, it keeps tension on the lateral delt instead of shifting to the front of the shoulder.
