1 - Anchor a resistance band behind you near floor level, then lie on your back holding the band with both hands.
2 - Extend your arms straight up over your chest with light tension in the band, and lift your knees over your hips with your knees bent to 90 degrees.
3 - Brace your core by gently pressing your lower back toward the floor and keeping your ribs down.
4 - Slowly extend one leg forward toward the floor while keeping the opposite knee bent and maintaining steady band tension.
5 - Pause briefly before your heel touches the floor, then return the leg to the starting position without letting your lower back arch.
6 - Alternate sides for the desired number of repetitions while keeping your arms stable and your breathing controlled.
