Begin by drawing your core in.
Raise each leg to approximately 90 degrees of hip flexion.
Hold it for three seconds before returning it to the ground. One
repetition includes raising and lowering each leg one time.
Complete three sets of 10 to 15 repetitions of this exercise.
Keep in mind the core should remain tight and engaged
throughout the movement of each leg. If you experience any
discomfort in the back with this exercise, you may discontinue or
preferably stay in the zone or range of motion that is
comfortable and doesn’t cause discomfort.
