Resistance Bands Lying Biceps Curls

Choose a band with the desired resistance and lie on your back on a mat.
Loop one end of the band around your feet and grab the other with a neutral grip (palms facing your body). You can spread your feet wide to pull the band taut.

Keeping your back, shoulders, head and elbows on the ground, curl the band as far as you can (roughly 90°) without raising your elbows from the ground.

Squeeze the biceps hard at the top of the movement for a second, then return to the starting position.
Repeat for the recommended number of repetitions.
