by AllCdnBoy: link Stand up straight with an exercise band under one foot. Ensure that you have a good grip on the exercise band and that you have a good amount on tension on the exercise band.
Inhale and lift the foot slowly, resisting against the band, until your hip and knee are at approximately 90 degrees.
Exhale and push your foot back down until it touches the floor. Enure that you maintain good posture throughout the exercise.
Repeat 10-12 times, the switch legs.
