Banded Kneeling Concentration Curl
Kneel on the floor and bring your right leg in front of you, knee bent. Secure one end of a resistance-band loop around your right foot and hold the other end in your right hand. Hinge forward from your hips, and place your right elbow against your right thigh just above your knee and extend your arm straight. Bend your elbow and pull the band toward your chest, keeping your elbow pressed into your thigh. Slowly lower to the start. Complete all reps on one side, then switch.
