Intensity: Light to moderate
Rest: 30-90 seconds between sets
Starting position: Lie on a mat on your back with both knees bent and feet flat on the floor. Rest your arms at your sides.
Movement: Slowly lift your right foot off the floor and straighten your leg while keeping your knees level. Pause, then slowly lower your foot to the starting position so that both feet are flat on the floor. Finish all reps, then repeat with the left foot. This completes one set.
Tips and techniques:
- As you lift your foot, straighten your leg as much as possible without locking the knee.
- Maintain neutral posture with your shoulders down and back.
- Exhale as you lift.
