band one arm overhead biceps curl

Stand with your feet shoulder-width apart and place one end of the band under your foot.

Hold the other end of the band with your arm fully extended overhead, palm facing forward.

Keeping your upper arm stationary, curl your forearm towards your shoulder, squeezing your biceps.

Pause for a moment at the top, then slowly lower your forearm back to the starting position.

Repeat for the desired number of repetitions, then switch arms.
